Drying oil - description of species, tips for choosing and instructions for self-cooking. Olif Oksol. Characteristics and features of the application Purpose, precautions, method of application of oxol drying oil intended for retail trade

Any kind of work on interior decoration rooms that are associated with painting wooden surfaces with oil paints cannot do without the use of drying oil. Even despite the recent emergence of new, more advanced formulations that perform the same tasks. What is drying oil? Why is it needed and how to use it correctly? - these are the questions, the answers to which will help to get a perfectly painted surface.

Drying oil types

At the moment, it is customary for experts to distinguish three types of drying oil: natural drying oil, drying oil "Oksol" and composite drying oil.

natural drying oil

Natural drying oil, the quality of which is strictly regulated by GOST 7931-76, consists of 97% vegetable oil of natural origin (linseed or sunflower), which has undergone special heat treatment, and 3% of desiccant.

1. Such drying oil reliably protects wood, however, it can only be used indoors.
2. In addition, natural drying oil has enough high cost by today's standards.

Drying oil "Oksol"

Drying oil "Oksol", the qualitative composition of which must comply with GOST 190-78, is a substance that has a slight odor and consists of 55% vegetable oil (linseed or sunflower), 49% white spirit and 5% desiccant.

1. "Oksol", on a par with natural drying oil, perfectly copes with its main task, namely, it protects wooden surfaces, forming a dense water-resistant film that does not blacken for a long time.
2. At the same time, Oxol drying oil is much cheaper than natural drying oil and, unlike the latter, can even be used to treat any surface outside the building.
3. The best is the Oksol drying oil, which has linseed oil in its composition, so it costs a little more than the one made on the basis of sunflower oil.

Composite drying oil

Composite drying oil is the cheapest drying oil with a characteristic pungent odor. It does not have a GOST number, so the composition of such a substance is not regulated at the legislative level, and production is carried out exclusively according to specifications.

1. Composite drying oils, as a rule, contain various chemical components, in particular, products of the petrochemical industry that are harmful and toxic to the human body (for example, petroleum polymer resins).
2. Therefore, such compositions are strictly prohibited for indoor use.
3. The smell of composite drying oil remains for a long time even with good ventilation in the room. this is the cheapest drying oil with a characteristic pungent odor.

Features of the use of drying oil "Oksol"

Drying oil "Oksol" is a quick-drying substance that has an increased hardness and forms a glossy coating on the surface of the material processed by it. It penetrates well into the pores of the tree, thereby emphasizing its structure.

• Drying oil "Oksol" is for sale in containers of various capacities, completely ready for use.
• It is necessary to apply such a substance on a dry surface, which, if necessary, is sanded in advance and thoroughly cleaned of dust or grease. Only after that do they move on to polishing.
• First, the composition is well mixed, if the drying oil has thickened during storage, it can be diluted with white spirit, nefras, and also, if desired, a solvent for varnishes and paints (oil and enamels).
• The drying oil is applied in a thin layer with a brush or a special roller. At the same time, all work must be carried out in a room that is well ventilated with an air temperature of at least 15 degrees Celsius and a relative humidity of 80%.

• The drying time of drying oil "Oksol" is approximately 24 hours, so the interval between each subsequent layer should be approximately a day.
• The rest of the unused drying oil can be stored for a year in a tightly closed container. For this, a dark, dry place inaccessible to children is suitable.
• To protect your hands during the polishing process, it is recommended to use rubber gloves. It is also important to avoid getting drying oil in the eyes. If drying oil has got on open areas of the body, then they are cleaned with rags or a rag soaked in vegetable oil. Then thoroughly wash everything with warm soapy water.
• With the help of drying oil "Oksol" it is also possible to putty small cracks by mixing it with sawdust until a thick homogeneous mixture is obtained.
• All work to avoid fire hazards must be carried out away from sources open fire.

Subject to all the recommendations, the work on polishing is quite simple, so almost anyone can do it. To learn more about the process of professional wood processing, you can watch the following video: [

Wood is very often used in construction and everyday life, but Oksol drying oil will help protect it from the destructive effects of insects and time. Let's get acquainted with the features of this composition, its characteristics and, of course, dwell on the practical part.

Purpose and principle of operation of drying oil

The principle of operation is that most oils, upon contact with oxygen, heat and light, thicken very intensively, and a thin layer completely hardens. This is due to fatty acid glycerides, because their amount and the degree of iodine number (an indicator of the number of double bonds in the carbon chain) are directly proportional to the rate of setting of the agent. Linen and hemp compositions of drying oil Oksol (GOST 190–78) are most effective, since the oils of these plants have 80% and 70% of glycerides of linoleic and linolenic acids, respectively, and the iodine number exceeds 150.

It should be noted that in its natural form, any vegetable oil freezes for quite a long time, and in order to accelerate this property, it is subjected to heat treatment. When heated, the hardening-retarding substances decompose, and salts provoke rapid oxidation. In addition, special compounds are introduced that contribute to its rapid drying (driers). As a result, the film deposited on the surface becomes solid within 6 to 36 hours.

Types of drying oils and their features

There are several varieties. Natural 97% consist of plant oils (sunflower or flax), the rest is occupied by a desiccant. Their main purpose is to dilute paints and treat wooden surfaces in rooms. Such drying oils are divided into oxidized and polymerized. The latter have a darker color, and products treated with it age faster.

Characteristics of drying oil Oksol (GOST 190–78) practically do not differ from natural. It is applied to internal and external works. But the composition also includes a solvent, which gives a pungent odor. Also, this type is cheaper than the previous one. Drying oil Oksol is produced in two grades - "V" and "PV". The first are created on the basis of flax or hemp oils. To create the second, petroleum polymer resins and other technical oils are used. Therefore, when working with drying oil, especially the PV brand, you should be extremely careful, wear respirators and protective gloves.

Often Oksol is marked "combined", "composite" or "semi-natural", which once again proves its origin. But sometimes it makes a fundamental difference for those who care about composition. Combined Oksol received rapeseed oil as a natural component, while sunflower oil was mainly used for production. But the situation was complicated by the fact that the new component belongs to the class of non-drying ones. Then it was pre-oxidized, and as a result, the combined Oxol received the same characteristics as the original version of the composition.

In the broad sense of the word, combined drying oil is obtained by mixing oils of several plants or those that have undergone different processing, the addition of synthetic substances and a solvent is also allowed.. The use of this option is more common in the preparation of paints. Drying oil of several brands is produced. In the designation, the first is the letter "K", followed by a number. If the marking indicates an even number, then the mixture is used for internal works, and odd - for coloring outdoor objects.

The last type is synthetic compounds. The basis for paints is alkyd drying oil, its cost is much lower than oil, which is a definite plus. Another type is compositional compositions. Their quality is not high enough, and due to increased toxicity, use is limited only to outdoor work. When choosing synthetic drying oils, one should be extremely careful, since if at least a small deposit of natural oils is present in them, then the layer after painting may not dry out for a very long time. The presence of such inclusions can be determined visually. This mixture has a reddish tint and a black precipitate.

Specifications - we study GOST

Drying oil Oksol (GOST 190–78) is characterized by the following properties. Due to the solvent, it has a pungent odor that does not disappear immediately. The time of complete drying is no more than a day. In addition, drying oil Oksol is highly flammable and toxic, therefore, when working with it, all safety rules should be followed.

According to GOST 190–78, marking is carried out depending on the composition, for example, drying oil “B”, which has excellent properties, is made only from hemp and linseed oil. It can be used both for breeding and for making oil paints. It is also acceptable to carry out external and internal painting work. Drying oil "PV", created on the basis of other technical vegetable oils(sunflower, grape, soybean, corn, etc.), but its use is limited to indoor work only.

Both types of Oksoli cannot be used for painting floors.

The technical characteristics of drying oil Oksol are indicated in GOST 190–78, but nevertheless we will dwell on them in more detail. The acid number for type "B" is no more than 6 mg KOH/g, and for "PV" - 8 mg KOH/g. The exception is drying oil based on sunflower oil, in which case this figure can reach 10. It is unacceptable for the sediment to exceed 1%, transparency must be complete. The mass fraction of non-volatile substances ranges from 54.5 to 55.5%, regardless of the brand. The flash point in a closed crucible is above 32 °C.

Drying oil Oksol is stored mainly in metal containers, but it is strictly forbidden to open it with tools that give a spark. When transporting, it is necessary to use the transport marking, namely the “Keep away from heat” sign. In more detail, all the characteristics of the composition, as well as safety requirements, test methods and acceptance rules are described in GOST 190–78.

The wisdom of coloring products with Oksol

Now consider the features of the use of drying oil Oksol. In general, there is no great difficulty in this, but we want to highlight some of the nuances, so we will analyze the order of work.

How to paint products with drying oil Oksol - a step by step diagram

Step 1: Preparatory Stage

Due to the pungent odor and toxic emissions, special attention should be paid to safety. All work is carried out in overalls, respiratory organs also need special protection, so you should prepare a respirator in advance, and rubber gloves are put on your hands. If the composition has got on the skin, then it is necessary to immediately wipe it off with a rag moistened with vegetable oil, and wash the damaged area well with warm water and soap. Avoid getting drying oil in the organs of vision. In addition, open flames are prohibited in the premises where work is carried out. And all lighting sources and electrical equipment must be reliably protected from explosions. And make sure you have good ventilation.

Drying oil or "boiled oil" (as it was called in ancient times) is a liquid composition that forms a film, which is formed as a result of the processing of vegetable oils (by oxidation or prolonged heat treatment) or fatty alkyd resins, also called desiccants. Drying oil is used as a protective impregnation for a variety of surfaces, as a primer before painting, as a basis for different types paint and even acts as a coating for interior decor.

Based on the components, drying oil is classified into the following types:

1. natural;
2. semi-natural;
3. synthetic.

The most widespread at the moment are the following types: natural, oxol drying oil and combined. In addition, alkyd, and even composite ones are often used.

According to GOST, the product in question must consist of at least 97% natural vegetable oil (drying or semi-drying, as well as mixtures thereof, mainly flax oil, occasionally sunflower, soybean, hemp oil).

During production, oils are subjected to prolonged exposure to high temperatures(not less than 300°C) for 12 hours, the next step is to use air blowing.

As a result, we get an oily, opaque, thick liquid consistency of rich brown, and sometimes greenish color with a slight smell of the base oil.

Drying oil based on flax oil looks like a light-colored liquid, transparent and oily.

Its main purpose is to perform the following tasks:

• priming of various surfaces: wood, metal or previously plastered;
• production and obtaining the required consistency of light-colored thick paint, putty, grease paste;
• as a paint compound light color used indoors and outdoors for painting metal structures, windows and doorways, flooring.

For complete drying room temperature it will take no more than a day.

Drying oil from hemp oil is dark in appearance and due to this it is mainly in demand, as well as drying oil from linseed oil, but when dark tones are required. Dries similarly for no more than a day.

Drying oil from sunflower oil dries much worse and it will take much more time than a day to dry completely. In addition, the film turns out, although quite elastic, but loses to the drying oils discussed above. according to indicators such as:

• hardness;
• strength;
• water resistance.

Table 1. Indicators of oil drying oils.

Representatives of this species also received their second name "oxol", technologically they are also made from oils, but subjected to oxidation, with the addition of solvents and desiccants. In this case, in percentage terms, the oil occupies 55%, the solvent (the most commonly used white spirit) is at least 40%. Due to this composition, the liquid has a rather unpleasant and pungent odor, which can last for some time even after drying.

At cost, oxol is much more cost-effective than natural, but at the same time it has practically no differences in basic properties and is almost identical in appearance.

Oxol made from flax oil is most valued - the film of such a product is distinguished by its hardness, elasticity, water resistance and, what is remarkable, the greatest durability.

For even greater reduction in cost, they are also produced from sunflower oil, but its film is much lower in terms of characteristics than from flax oil.

Drying oil combined

This type of drying oil is almost identical to semi-natural, except for the percentage: the percentage of oil is about 70% and 30% remains on the solvent. They are obtained by polymerization and dehydration of drying and semi-drying oils. The main direction for the use of this product is the production of thick paints. Industrially produce grades K-2, 3, 4, 5. The time of complete drying does not exceed a day.

Table 2. Indicators of combined drying oils.

Drying oils alkyd

The thermochemical processing of the semi-drying and non-drying oil gives the resulting alkyd drying oil a high drying capacity. In addition, in terms of the totality of properties, it has higher values ​​for hardness, durability, water resistance and weather resistance than oxol drying oils. Thereby this species is considered as more promising, since it allows to reduce the cost of vegetable oil for production. The only drawback can be called thickening during storage, which is due to the fact that free fatty acids, of which a large number react with mineral pigments and insoluble metal soaps appear. This does not allow using the product for the manufacture of thick paint, but does not prevent mass use for diluting them to the required consistency.

This type is currently considered the cheapest and this is what made it quite widely used. After all, the main component is not natural oil or resin, but their substitutes, most often various products obtained during oil refining. The composition of such drying oils may be different, since they are produced not on the basis of GOST, but according to technical conditions. In their appearance, they also differ significantly - the color is often light, the transparency is much higher than that of oil-based formulations. Also, the disadvantages include a very pungent odor and a longer drying process. The most common representatives are slate drying oil and, of course, ethinol.

Oil shale oil looks like a liquid of a darkish color, as it was noted, there is a pungent smell and is a derivative of the process of oxidation of shale oil with further dissolution in xylene. Dries a little more than a day. It has good weather resistance. The main direction of use is dark tinting, dilution of paints to the required consistency, which are used mainly for outdoor work and sometimes indoors for painting surfaces of their metal, wood and covered with plaster. It is forbidden to use this drying oil for application on floor materials and objects used in everyday life.

Drying oil ethinol, on the contrary, looks like a transparent liquid of a lightish tone, with the same specific smell and is made from waste obtained in the manufacture of chloroprene rubber.

The film dries quickly after application, is glossy, very hard, resistant to alkali and acid, but, unfortunately, with poor weather resistance.

Often this species is used as an additive to other drying oils, but not more than 15%. The main direction was the manufacture of paints and primers for metal on its basis.

Table 3. Indicators of synthetic drying oils.

Drying oil application

Work procedure

1. Before starting work, it is required to clean and degrease the surface to be treated.
2. If the composition on semi-natural drying oil is used in the work, then it is recommended to apply it only on a dry surface.
3. When using drying oil and paint products based on it, it is recommended to apply with a brush, roller or paint sprayer.

The average operating expense when using semi-natural drying oil is from 150 to 200g. on cubic meter. As already noted, the duration of drying during natural drying will take no more than a day.

Drying oil storage

Based on the fact that the drying oil contains oil and solvents, it belongs to explosive and flammable materials, therefore, in the room where work is performed, natural ventilation or equipment is required forced ventilation in explosion-proof execution. In case of contact with human skin surfaces, it is necessary to wipe off and rinse well with soapy water. When storing drying oil, it is required to ensure that the container is tightly closed and protected from moisture and sun rays, was located far from the fires and electrical appliances. When thickening, it is allowed to dilute the drying oil with any solvent available to you suitable for oil paints in a ratio of 1:10.

The choice of drying oil

Before you buy drying oil, you need to carefully consider what is in the container. First, you should determine by color whether it corresponds to the declared type of product. In addition, you should carefully read the description of the components and check whether it complies with GOST, if you buy semi-natural or natural drying oil. They will have a certificate of conformity, and for a composite one - only hygienic. In general, you should be careful with the use of the latter, since it is toxic and it is important to note that it should not contain oil residues (the so-called fuse) and osprey (oil refining residues), otherwise the drying process will become endless. And finally, it should be noted - carefully inspect the liquid for uniformity, sediment or mechanical particles should not be present.

As noted earlier, the main purpose of these products is to treat various surfaces, they are also indispensable in the production of paints. If you stop at surface treatment, then drying oil for wood is great. It is used both for impregnation of products and walls in general. But for external work, it is recommended to apply drying oil only for preparation before further painting. And it would be more optimal to use oxol or alkyd drying oil. natural better fit for interior work (due to environmental friendliness and lack of smell) and to obtain the required consistency of paints.

In the manufacture of paints, almost all types are involved. So, natural becomes the basis for thickened, and alkyd is an excellent base for oil. Only composite is not used due to low quality.

This paint opens up more possibilities for you, and you can paint wooden flooring when it suits you, not when the weather permits.

Fashion on natural materials in construction, furniture production, interior decoration has already become a tradition. And it is wood that continues to be in trend due to its environmental and aesthetic properties. But, unlike artificial materials, wooden coatings and structures can deteriorate under the influence of adverse environmental factors, such as moisture, direct sunlight.

Currently drying oil application decreased significantly, perhaps due to the appearance on the construction market, a large number of funds with a new composition. Although there are still consumers who have not abandoned the use of drying oil in repair and construction work.
Now three types of drying oil are produced: natural, combined and oxol.

natural drying oil

Natural drying oil consists of: 97% vegetable (linseed) oil, 3% desiccant. It is an opaque thick liquid, dark Brown, has a slight odor. It is mainly used for dilution of paints and impregnation of wooden surfaces. For work indoors, natural drying oil is ideal, it is practically odorless, easy to use, does not emit toxins. For outdoor work, the use of natural drying oil is not beneficial.

Drying oil oksol

The purpose of oxoli is to work indoors, it can process wooden and plastered surfaces, it improves the adhesion of paints and fillers. For outdoor work, do not forget that the oxol is intended for temporary preservation of the material; varnish, paint or enamel should be applied on top. Sunflower oil-based oxol can be a good alternative to the buyer; it is also used when working indoors.

Composite drying oil

Composite drying oil: its composition varies to some extent, but mostly these are synthetic substitutes, or rather, oil refining substances. Therefore, it is less costly. The difference between composite drying oil and natural and oxol in the external factor. It is liquid and lighter, sometimes has a reddish tint. A pungent smell and a long drying time also distinguishes composite drying oil from all the others. It is not used to work indoors, this drying oil is very toxic and harmful. In addition, even after drying, composite drying oil continues to smell for many more years. It has not found application in the paint and varnish industry, since the resulting coating is of poor quality.

We study the label

For processing and impregnation of wooden surfaces, all types of drying oil are used. The resistance of drying oil to weathering, loses to other paints and varnishes. In the end, it must be said that when purchasing drying oil, you need to be very careful. Pay attention to packaging and drying oil color. Examine the label, which should contain all information about the manufacturer of this product, the number of GOST or TU. Read about the composition of the product, instructions for its use. Check the availability of a certificate of conformity and a hygiene certificate. The first is issued for natural drying oil and oxol, the next for composite drying oil. The degree of drying oil quality can be determined by its homogeneous composition, it must be without mechanical additives and without sediment. The weaker the smell, the better.

Description

Drying oil "Oksol" refers to universal means for protecting wood from external influences or processing plastered surfaces. Order material at manufacturer's price for thinning paints, creating primer coats before using oil-based paints. After applying the composition, a coating is formed, which is characterized by wear resistance, moisture resistance. When applied this tool the consumption of paint and varnish products is significantly reduced.

Features of drying oil for coloring "Oksol"

The composition is a mixture of various vegetable oils (sunflower, soybean, etc.) with the introduction of solvents, such as turpentine, white spirit, desiccant (to speed up drying).

The material is flammable and toxic. When using it, be sure to ventilate the room, use respiratory and skin protection products.

The drying period of the coating is more than 24 hours at +20 degrees Celsius.
