Drying oil: types and purpose. Choosing drying oil "Oxol Drying oil oxol technical characteristics consumption

Natural drying oil, specifications which differ significantly from other brands of this substance, it does not always turn out the right choice for processing a particular surface. Perhaps a synthetic or combined composition will be much more effective in your case. How to choose the right drying oil? Let's figure it out.

What is drying oil and its use

So, drying oil... A transparent liquid substance with a fairly thick consistency. Color can vary from cherry to yellow. Has film-forming properties.

It is made from vegetable oils that have been thermally processed, or alkyd resins. It necessarily contains a special substance that significantly speeds up the drying time - a desiccant.

There are different types and brands. Some of them can only be used indoors, while others are better indoors. outdoors. But how to choose such a composition so as to reduce costs and not lose technical characteristics?

Types and brands of oil drying oils

Oil formulations are produced through filtration and special heat treatment from vegetable oils. Drying agents are added to the resulting composition in small quantities. They can be salts of various metals, for example, manganese, iron, lithium, zirconium, cobalt and others.

If the drying agent contains compounds of several metals, then the drying oil drying rate increases significantly.

In oil drying oils the content of driers is insignificant, since with their excess the coating very quickly darkens and becomes brittle, i.e. begins to collapse.

Divided into:

natural. GOST 7931-76, natural drying oil (we carefully study its technical characteristics before purchasing), consists of plant oils (flax or sunflower). It contains up to 97% of these oils. The remaining 3% is occupied by the drier. It is divided into polymerized and oxidized (oxidized). Oxidized drying oils have a slightly darker color than polymerized ones, and surfaces coated with them age faster. It has a black-brownish color. It is an opaque liquid with a thick oily consistency and a slight odor. It is used for preparing thickly rubbed paints, as well as for impregnating all wood products inside buildings;

drying oil oxol, its GOST 190 78 (technical characteristics are indicated on the label) - this drying oil differs from natural oil in that it contains a solvent such as white spirit. The oxol contains 55% oil, 5% drier, and the rest is white spirit. She has a very strong and bad smell, which gives it a solvent. It remains on the treated surface for quite a long time for a long time. Externally and in its properties, oxol is almost no different from natural drying oil, but much cheaper. Oxol is produced in the PV and V grades. They differ in that “B” uses hemp or flax oil, and “PV” uses other oils, including petroleum-polymer resins (petroleum-polymer drying oil is by-product petrochemical industry). When using the PV brand, you must wear gloves and a respirator. Drying oil grade B is not used for painting floors. Oxol can be used both inside and outside the building;

combined drying oil. It is obtained by mixing and oxidizing oils from various plants or differently processed, with the addition of a solvent or synthetic drying oils. Drying time is determined according to GOST 19007. Combined drying oil is used mainly for preparing paints, and not for diluting them. This type comes in several brands: K 2, K 4, K 3, K 5, K 12. Even numbers are used for indoor work, and odd numbers can also be used outside. For example, combined drying oil (grade K 3) consists of a small amount of drying agent, solvent (usually white spirit) and drying oils. It is transparent, yellowish in color. Complete drying occurs within 24 hours. Recommended to use in small portions, as it quickly forms a film. Can be used to prepare any oil paints and for impregnation of wooden parts, for mixing plaster. Combined drying oil (grade K 2) is slightly different in color from K 3, it is slightly darker. It is used in the same way as K 3, but for interior work.

They are based on synthetic substances, such as by-products from the processing of shale, oil, gas and other substances with the addition of the necessary components. There is no GOST for them; instead, TU is used.

Alkyd drying oils used as a base for preparing paints. They are cheaper than oil ones, which is often the decisive factor in their favor. Composite drying oils They are rarely used in the production of varnishes and paints, since the resulting coating is of low quality. Due to some toxicity and a pungent odor, they are used outdoors.

Synthetic drying oils differ from natural ones for a long time dry and have no color. But be careful when purchasing such a composition: there may be surprises. If there is even a small amount of fus (precipitate vegetable oil), then the drying time of the paint of which it is a component can take years. Moreover, such paint may not dry at all. The presence of fuse can be determined by its characteristic reddish color and the presence of a dark sediment.

• Natural drying oils are quite expensive; they are used indoors for coating wooden products and in oil paints. The outside of products coated with such compounds will have to be processed again and again, which is very impractical.
• Oxol is cheaper, but it also protects the surface from wood pests worse, although it forms a durable, water-resistant film. The cheapest oxol is produced at sunflower oil. It can be used inside and outside the building. As an alternative - combined.
• Synthetic ones are an option for the budget-conscious, but they have a very unpleasant odor that is harmful to human health, so they can only be used outside, covering surfaces in non-residential buildings. When using them, gloves, an apron, and a respirator are required.

Before purchasing, be sure to thoroughly study the data of GOST or TU drying oils. Then you will not regret your choice.

Drying oils provide excellent protection of wood products from insects, mold and mildew, and precipitation. In the article we will talk about the classification of such compositions and their features, and also describe in detail one of their most popular varieties.

The compositions we are interested in are made from various oils, to which are added solvents and driers - compounds that include strontium, lead, iron, lithium, cobalt, and other chemicals. elements. All drying oils are divided into:

• natural;
• alkyd;
• combined;
• synthetic;
• semi-natural.

The natural composition consists of 97% sunflower or linseed oils, which are subjected to heat treatment. The cost of such drying oils is high. Now they are used quite rarely. They are usually used for dilution paint and varnish compositions. The natural composition can be used to treat any wooden surface, provided that it is located indoors. Flax compositions are also used for the production of special lubrication pastes, putties, dilution of thickly rubbed paints and putties.

Semi-natural and combined drying oils have a more affordable price. From natural compositions they differ in that volatile group solvents (for example, white spirit) are necessarily added to them. The most famous semi-natural composition is Oksol. We will look at it in the next section. Alkyd drying oils are made from solvent-diluted and oil-modified resins. And synthetic compounds, which are often called composites, are made from rubber processing products, materials from the oil and coal industries. They do not contain natural oils. Such drying oils are not used indoors due to their increased toxicity. The only advantage of synthetic solutions is their low price.

Oxol - a composition with special characteristics

Drying oil Oksol belongs to a group of semi-natural compounds used to protect wood, manufacture and dilute paints (on oil based, thickly grated). Let's see what this composition is made of. It contains 55% natural oil, 40% solvent (in most cases - white spirit, less often - nefras or turpentine), 5% drier. The composition is produced in accordance with GOST 190–78. More on its provisions below.

Oxol is divided into two brands. The first - B, is made from hemp and linseed oil. This drying oil can be used for processing wood both indoors and outdoors. The second is PV, made from soybean, camelina, sunflower, grape or corn oil. The composition is used exclusively for internal painting works. Nuance. Both brands of oils are not intended for use on floor surfaces.

Gosstandart 190–78 describes all technical characteristics of Oksol. Let's highlight the most important of them:

• acid index – up to 6 mg KOH/g (grade B); up to 8 (PV);
• Drying period – 20–24 hours
• viscosity (conditional) – 19–25 s (PV), 18–22 (V).

Oxol is characterized by complete transparency, easy flammability and a pungent odor. The latter, after using drying oil, does not disappear from the room for quite a long time. At factories, Oxol is packaged in metal containers (cans of different capacities) or plastic. Important! When opening metal containers, you should use a tool that does not allow a spark to appear (do not forget about the flammability of the composition). Oxol should not be used near operating heating equipment or sources of open fire. If the composition catches fire, it can be extinguished by any means (asbestos cloth, steam and chemical foam, gas, fine water).

Experts advise home craftsmen to use Oxol based on linseed oil. It dries completely in 20 hours and has a less unpleasant odor than drying oils made from other technical oils.

True, the cost of linen compositions is slightly higher. At the same time, Oxol of any brand guarantees a durable, water-resistant film on the treated surfaces that does not turn black for a long time.

Using semi-natural drying oil - how to apply the composition?

Since Oxol has a pungent odor and belongs to the group of toxic oil compounds, we adhere to some mandatory rules when working with it. Firstly, we carry out the planned painting activities wearing a respirator, rubber gloves that protect our hands, and thick overalls. In this case, the risk of poisoning by drying oil vapors and contact of its drops with the skin is significantly reduced. If, nevertheless, Oxol lands on a person’s skin, it is necessary to immediately wipe it off with a clean rag. After this, thoroughly wash the damaged area with soapy water.

Secondly, work with drying oil indoors is allowed only if there is effectively functioning ventilation. Direct processing scheme wooden structures Oxol looks like this:

1. 1. Clean the product from the old coating (varnish, paint, etc.). Remove from the surface greasy spots, dust, other contaminants.
2. 2. Dry the cleaned structure. If there are significant roughnesses on its surface, we additionally sand the wood.
3. 3. Open the jar of Oxol. Mix the composition well. If you are using a container from which the composition was taken earlier, add a little white spirit to the jar. Then we can easily stir the thickened mass.
4. 4. Using a brush or roller, apply drying oil to the product. Make the layer not very thick.
5. 5. We wait 24 hours. Then we re-paint the product with Oxol. If it is necessary to apply a third layer, wait another day. And only after this we treat the surface again with the described composition.

The solvent content in the finished Oxol solution is no more than 40%, and the remaining 5% is the mass fraction of the drier. The solvent contained in Oxoli gives the entire mixture a characteristic unpleasant and pungent odor, which persists for some time even after drying. This drying oil, due to the presence of various components in its composition, is significantly cheaper than natural drying oil, but practically does not differ from it either in appearance or in properties.

The characteristics of drying oil depend on the vegetable oil used in the composition; it is divided into two subspecies. Higher quality drying oil is made using linseed oil. This coating is hard, water-resistant, elastic and has maximum durability. Accordingly, cheaper drying oil contains other oils (sunflower, soybean, corn and others).

Characteristics of Oxoli

Depending on the components used, it is produced Oxol grades B and PV. Drying oil grade B is produced using hemp or linseed oil. It is used in the paint and varnish industry in the production of oil-based paints, as well as for diluting various thick-based paints that are needed in interior and exterior painting work.

Drying oils of the PV brand are based on sunflower, safflower, grape, corn or other oils, and it is also possible to partially replace these oils with petroleum-polymer resins. To produce this brand of drying oil, oils that can be used in the food industry are not used.

Oxol is used for special impregnation of various wooden surfaces or for treating plaster before painting. Drying oil Oxol, the technical characteristics of which are specified by the relevant GOST, dries quickly (no more than a day), has excellent hardness and creates a glossy effect on the surface.

Reminder for those working with Oxol drying oil

The solution should be applied to a surface that has been previously dried and free of dust and dirt. All work is carried out at a temperature not lower than +10 °C. Relative air humidity should not be more than 80%. At this temperature, Oxol dries in no more than a day.. If the solution has thickened, then it can be diluted with nefras, turpentine or white spirit, as well as their mixtures.

This material is a flammable and toxic liquid that is dangerous at elevated temperatures. All these characteristics are determined by the properties of the components (oils and solvents) included in the composition.

Open flames are prohibited in areas where this liquid is used or stored. Electrical equipment and lighting sources must be explosion-proof. The drying oil itself should be stored in a carefully and tightly closed container, protected from direct sun rays, as well as various moisture levels.

When using this liquid, the room where this occurs must be well ventilated. When to use drying oil Oxol PV, the manufacturer recommends protecting your respiratory system with a respirator, and open areas leather - overalls and rubber gloves.

When hit of this material If any contact occurs on the skin, quickly wipe it off with a soft cloth and wash the area with warm soapy water. Do not allow drying oil to get into your eyes!

Any type of work on interior decoration rooms that involve painting wooden surfaces with oil paints cannot do without the use of drying oil. Even despite appearing in Lately new, more advanced compounds that perform the same tasks. What is drying oil? Why is it needed and how to use it correctly? - these are the questions whose answers will help you get a perfectly painted surface.

Types of drying oil

On this moment Experts usually distinguish three types of drying oil: natural drying oil, Oxol drying oil 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 natural origin(flaxseed or sunflower), which has undergone special heat treatment, and 3% from drier.

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

Drying oil "Oxol"

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

1. “Oxol”, along with natural drying oil, copes well with its main task, namely protecting wooden surfaces, forming a dense, water-resistant film that does not turn black for a long time.
2. At the same time, Oxol drying oil is much cheaper than natural drying oil and, unlike the latter, it can even be used to treat any surfaces outside the building.
3. The best drying oil is considered to be “Oxol”, which contains linseed oil, so it costs a little more expensive than that one, which is produced 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, therefore the composition of such a substance is not regulated at the legislative level, and production is carried out exclusively according to technical conditions.

1. Composite drying oils, as a rule, contain various chemical components, in particular, harmful and toxic to human body products of the petrochemical industry (for example, petroleum polymer resins).
2. Therefore, such compositions are strictly prohibited from being used indoors.
3. The smell of composite drying oil lasts 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 "Oxol"

Drying oil "Oxol" is a quick-drying substance that has increased hardness and forms a glossy coating on the surface of the material treated with it. It penetrates well into the pores of the wood, thereby emphasizing its structure.

• Drying oil "Oxol" is sold in containers of various capacities, completely ready for use.
• This substance must be applied to a dry surface, which, if necessary, is sanded in advance and thoroughly cleaned of dust or grease. Only after this do they move on to sanding.
• First, the composition is mixed well; if the drying oil thickens during storage, it can be diluted with white spirit, nefras, and also, if desired, a solvent for varnishes and paints (oil and enamels).
• Apply drying oil 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 Oxol drying oil is approximately 24 hours, so the interval between each subsequent layer should be approximately a day.
• The remainder of the unused drying oil can be stored for a year in a tightly closed container. A dark, dry place out of reach of children is suitable for this.
• To protect your hands during the sanding process, it is recommended to use rubber gloves. It is also important to prevent drying oil from getting into your eyes. If drying oil gets on open areas of the body, they are cleaned with a rag or rag soaked in vegetable oil. Then wash everything thoroughly with warm soapy water.
• Using Drying Oil "Oxol" you can also putty small cracks by mixing it with wood sawdust to obtain a thick, homogeneous mixture.
• All work to avoid fire hazards must be carried out away from open flame sources.
