Any type of work on interior decoration rooms that involve painting wooden surfaces 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.

At the moment, experts usually distinguish three types of drying oil: natural drying oil, Oxol drying oil and composite drying oil.

Natural drying oil, the quality of which is strictly regulated by GOST 7931-76, consists of 97% vegetable oil natural origin(linen or sunflower) that has passed a special heat treatment, and 3% from the drying agent.

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

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.

“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.
At the same time, Oxol drying oil is much cheaper natural drying oil and, unlike the latter, it can even be used to treat any surfaces outside the building.
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 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.

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).
Therefore, such compositions are strictly prohibited from being used indoors.
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.

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 relative humidity 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 bodies, then 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 until a thick, homogeneous mixture is obtained.
All work to avoid fire hazards must be carried out away from sources open fire.

Has long been used to protect wood from negative impacts: moisture, – used oil impregnation– drying oil. Treated surfaces wooden structures acquired persistent protective properties. Today's market building materials offers wide choose impregnation

A film-forming liquid product is a product of thermal processing of vegetable oils using additives. Drying oil can be called boiled butter. There are other types of impregnation created from artificial components.

With the advent of effective materials for protecting wooden structures outside houses and buildings, drying oil began to be used only to cover the finishing of wooden fences indoors.

Weight natural oil in open space under the influence of warm temperatures sun rays and oxygen acquires a thick consistency. The substance applied in a thin layer begins to dry slowly, and as a result of polymerization, the coating turns into a film high density. Drying is promoted by polyunsaturated fatty linoleic and linolenic acids (glycerides).

Among large quantity vegetable oils highest ability Hemp oil also has a quick drying properties. Sunflower, poppy seed, nut, rapeseed, castor and other raw materials almost do not thicken due to their low glyceride content. They are not subject to complete polymerization.

To significantly reduce drying time, vegetable oils are heated by adding a drier (metal compound). As a result of heat treatment chemical compounds, affecting the slowdown of the polymerization process, are broken down into inert substances. Using this technology, wood is impregnated - drying oil. Various formulations, applied in a thin layer on wood, or drying (from 6 to 36 hours), form a hard elastic coating. On average, the compositions dry within a day.

The product impregnates upper layer wood, creating a film with high adhesion. It is used to treat surfaces before painting. oil compositions, which significantly reduces paint consumption. The treatment is also carried out before subsequent coating of wooden surfaces with wax.

Building materials factories fill the market with many types of impregnations with different characteristics. They are classified as:

natural;
semi-natural – oxol;
combined;
synthetic;
alkyd and composite.

Natural drying oil is produced according to GOST 7931-76. The product is obtained by thermal processing of natural hemp and linseed oils. The oil must not be diluted with solvents or other chemicals. The use of sunflower oil is excluded. A desiccant is added to the prepared mass - with manganese, cobalt or lead in a volume of 3% of the total mass of the material.

IN industrial production heated raw materials are languished (+300 ˚C) in special tanks for 12 hours. The resulting mass is polymerized or standard impregnation. Sometimes the cooking process is accompanied by air blowing. This impregnation is called an oxidized or oxidized agent.

The impregnation looks like an oily translucent substance of different shades. The liquid product has a faint sweet smell of vegetable oil. Flaxseed oil is much more transparent than its hemp counterpart. Therefore, its quality is assigned premium. All natural liquids reach complete drying within 24 hours.

Oxol contains natural oils or mixtures thereof (sunflower, soybean, corn, etc.), occupying up to 60% of the total volume. Required condition production of oxol - the use of up to 40% petroleum polymer resins in a mixture with drier. When producing semi-natural impregnation, it is allowed to use (GOST 190-78) petroleum-derived dryers containing manganese, cobalt, lead or mixtures thereof.

The composition of oxol includes the following components in % ratio:

oils and resins – 55%;
white spirit or turpentine – 40%;
desiccant – 5%.

Unlike natural products, oxol has a sharp unpleasant smell which can last for a long time. The advantage of the product is low price. The highest quality drying oil is considered to be oxol from linseed oil. The impregnation is characterized by durability, increased elasticity, water resistance and hardness.

The combined compositions are similar in production method to oxol. The difference lies in the proportions of the mixture of oils (70%) and solvents such as white spirit (30%).

The purpose of impregnation is protection, coloring of wood, dilution of thick oil paints. The liquid is applied to the plaster before oil painting. Dries completely in 24 hours.

Combined drying oils are produced in two grades: K-2 and K-3. Each comes in 2 varieties.

The K-3 brand product is used for treating surfaces both indoors and outdoors of buildings and structures. They cover it street poles And wooden buildings for protection against precipitation and the appearance of negative organic formations. The second grade K-3 is slightly darker than the 1st grade, which is completely transparent.

K-2 does not have a strong odor and gives wooden structures a noble fawn tint, which is used before coating surfaces with varnish. Impregnation does not withstand negative atmospheric conditions well, so it is used only indoors.

This type of drying oil contains inorganic substances. They are a product of petroleum refining. Popular synthetic impregnations are shale drying oil and Ansol artificial drying oil.

Shale impregnations are made from petroleum film-forming components. A special catalyst is added to the mixture, and then the mass is diluted with shale gasoline. This product contains:

raw materials from diesel shale oil;
shale gasoline;
raw materials from shale generator oil;
solvent.

The manufacturer adds natural vegetable oils to the impregnation in a volume of up to 20%. A modified drying oil is prepared by mixing all the ingredients followed by heat treatment. Drying time – 24 hours.

Ansol is a completely synthetic product without the inclusion of vegetable oils. Impregnation is prepared from petroleum products. Petroleum-polymer drying oil is diluted with a solvent to bring it into technical condition. Because of this, drying oil has a sharp, unpleasant odor. To get rid of this faster, you need to ventilate the premises well. Over time, treated surfaces cease to emit an unpleasant odor.

The undeniable advantage of synthetic impregnation is its low price.. Due to intolerance to sunlight, Ansol is used only for interior works. The product performs well upon completion plastering works. Drying oil reliably impregnates the porous surface of the plaster and strengthens it before painting. If we compare the economic benefits of using different types drying oils, then Ansol claims first place.

The choice of impregnation type is influenced by several factors. The following items can be included in this list.

To treat surfaces made of expensive wood, impregnations made from linseed and hemp oil are used.
It is better to treat the surfaces of enclosing wooden structures from the outside with oxol or combined compounds.
Synthetic liquids are suitable for coating wooden surfaces in non-residential premises. They process wood supporting structures roofs.
Treating large areas with Ansol brings significant savings.
It is better to take drying oil in a transparent or translucent container. If sediment is detected, it is better not to buy such a product.
The cost and type of solvents are of considerable importance. When using a spray gun, the impregnation is diluted with a solvent in a 1:1 ratio.
When purchasing, it is better to contact a construction supermarket, where you can get information about drying oil from professionals.

Cost - from 200 rubles per liter. Containers with a volume of up to 10 liters are available for retail sale.

If you have a home workshop, you can prepare drying oil yourself. Drying oil good quality obtained from linseed oil. But if there is nowhere to get it, they make a homemade impregnation from natural sunflower oil - this is a publicly available and cheap raw material.

The impregnation preparation process includes three stages:

preparing the oil base;
preparation of drier;
final production of drying oil.

The container is filled halfway with oil and placed on the stove. When the base is heated to 110–120˚C, the water will evaporate and foam will begin to appear.

Then the foam will subside. Continue cooking for 3–5 hours, increasing the heating temperature to 270˚C. If the edges of the pigeon feather curl up in the oil, then the heating level is sufficient.

Drying agent is an auxiliary reagent that sharply reduces the drying time of drying oil. The substance is also added to oil paints.

You can make a desiccant like this:

100 parts by weight of rosin are melted at a temperature of 150 ˚C in a separate container.
5 parts of manganese peroxide are gradually added to the molten mass after the foam settles again.
The mixture is brought to 200 ˚C and kept for 3 hours. The material should become transparent.

The drier is carefully introduced into the oil base over low heat, monitoring the foam level. After the foam has completely subsided, the mixture is boiled for 5–10 minutes. Then the container is removed from the stove and the mixture is left to cool.

The storage conditions for viscous impregnation are simple. Store drying oil in open areas for no more than 3 days. The impregnation must be contained in a closed container. In conditions warehouse drying oil retains its qualities for about three years. If during this period sediment appears at the bottom of the vessels, then the product becomes suitable only for ignition. Temperature Drying oil storage ranges from –40 to +40 ˚C.

Any type of interior decoration work that involves painting wooden surfaces with oil paints cannot be done 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 whose answers will help you get a perfectly painted surface.

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 drier.

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

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. They differ from natural compositions in that volatile 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.

Drying oil Oxol belongs to the group of semi-natural compounds used to protect wood, produce 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 everything specifications Oxols. 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 evaporate from the room sufficiently for 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.

Since Oxol has a pungent odor and belongs to the group of toxic oil compounds, when working with it we adhere to certain mandatory rules. Firstly, we carry out the planned painting activities wearing a respirator to protect our hands rubber gloves and thick overalls. In this case, there is a danger of poisoning by drying oil vapors and getting its drops on skin decreases significantly. 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. The immediate scheme for processing wooden structures with Oxol looks like this:

1. We clean the product from the old coating (varnish, paint, etc.). Remove from the surface greasy spots, dust and other contaminants.
2. Dry the cleaned structure. If there are significant roughnesses on its surface, we additionally sand the wood.
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. Using a brush or roller, apply drying oil to the product. Make the layer not very thick.
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.
