Description

The invention relates to the preparation of paints and varnishes. In the production of oil paints as a film-forming substance, vegetable oils are used (solar, flax, hemp and others). The known modification of vegetable oil structured in the process of polymerization at 200-280 with rubber, which allows replacing up to 50% of vegetable oils in the production of drying oil Cl. However, the process of polymerization of plant oil and rubber is carried out at a high temperature, which requires high energy consumption, and also leads to a decrease in some indicators characterizing the quality of the drying oil produced. It is known that raw tall oil, processed with lime or many atomic alcohols, allows replacing up to 30% of vegetable oil in the case of production of C27 drying oil. However, dark-colored drying oils are obtained, which can be used to make oils. colors only dark colors. It is known to use in organic oils of silicone compounds for the purpose of replacing vegetable oil C3. However, the highest quality drying oil is obtained when it contains no more than 5% of silicone compounds. The increase in content, last in drying oil leads to a decrease in the quality of drying oil. The closest to the technical essence and the achieved effect to the invention is ma, sweet-composite linseed oil f4 of the next soetaw, wt.% Sunflower oil 50.2 Lac oil-rosin 5.0 Sikkativ NF-16.5 White spirit 38.4 A disadvantage of the known varnish is the use in its composition of up to 50% of the food product — sunflower oil, as well as a scarce and expensive product — rosin. In addition, the process of obtaining oil-rosin linseed is a multi-step process and includes, in addition to the oxidation of sunflower oil, the following stages: the preparation of rosin resinate, the preparation of oil-rosin and lacquer. The aim of the invention is to reduce the consumption of vegetable oil, improve the color of linseed oil and simplify its production technology. The goal is achieved by the fact that linseed oil, including oxidized sunflower oil, oil siccative and white spirit, contains lead-manganese and cobalt siccativa as an oil sikkativ, and the following ratio of components, wt. oxidized sunflower seeds 29,00-44,00 Polyterpenes or hydroxypolyperpenes5,0-20,0 Lead-manganese dryers 4,5,5,5 Cobalt dryers 0,5-1,5 White spirit 44-46 Polyterpenes are produced by polymerization of terpene hydrocarbons included in the composition of turpentine G5L. They are a clear, oily liquid from light yellow to brown in color with no irritating odor, a density of 0.940 g / cm and a kinematic viscosity. at 800–900 cSt, containing 75–90% of dimers with molecular weight of 272 and 10–25% of solid polyterpenes with a degree of polymerization of 3-5 and a molecular weight of 400–680. The average molecular weight of polyterpenes is 300-420. Hydroxypoliterpenes are a clear, oily liquid from light yellow to brown in color with a faint turpentine odor with a density of 0.945-0.980 g / cm and kinematic viscosity at 20 ° C 2600-3200 cSt, containing 75-90% of the product of dimer oxidation of molecules with a molecular weight of 288- 304 and 10-25% of the product of oxidation of solid polyperpenes with a degree of polymerization of 3-5 and a molecular weight of 416-710. The average molecular weight of hydroxypolymerins is 320-450, Hydroxypolyperpenes are obtained by the oxidation of polyterpenes C6J. The proposed drying oil is obtained as follows. The oxidized sunflower oil, polyterpenes or hydroxypolyperpenes, svijtso-manganese and cobalt driers and mineral spirits are loaded into the reactor. The resulting mixture is stirred until a homogeneous mass is obtained, the stirrer is turned off and the resulting drying oil is put on the TPP. Example 1. The reactor (conical flask) equipped with a stirrer is charged with the components in the following ratio of may.%: Sunflower oil oxidized 44.0. Hydroxypoliterpenes or psaliterpenes 5,0 Oil desiccants: lead-manganic 4.5 cobalt L, 5 White spirit 46,0 At the end of the batch, turn on the stirrer and mix for

5 MIN to obtain a homogeneous mass. At the end of the stirring, the stirrer is switched off. The resulting drying oil is put on type.

Example 2. In a reactor (conical flask) equipped with a stirrer, the components are charged in the following ratio (% by weight,%:.

Sunflower oil oxidized, 39/0 Oxy Loliterpenes or polyterpenes. Mild lead-manganese driers. 5.0 cobalt1.0

In tab. 1 shows the properties,. an alcohol containing polyterpenes and oxypoliterpenes.

As can be seen from the table. 1, the introduction of polyterpenes or oxypolyperpenes

0 in the formulation of drying oil allows significantly (by 2-3 times) to reduce the color of drying oil in comparison with the known one, which makes it possible to use it for the preparation of paints of light tones

5 to reduce the consumption of oxidized sunflower oil and completely eliminate the use of rosin, which is an expensive raw material.

The proposed slifa can be used as a binder

0 for pigmented matt coatings of light colors, which are currently used in widespread demand. Drying oil has a wide range of applications and can be used to prepare thick-rubbed paints ready for use.
