Description

one

The invention relates to a paint coating: a juicy coating, in particular to paints and varnishes used for painting floors. The paintwork materials for the floor have a number of specific requirements determined by the operating conditions; first, the coatings must have high hardness, increased wear resistance, good gloss and a satisfactory decorative appearance. Since these materials are widely used for domestic purposes, they must contain a minimum amount of solvent.

Famous floor paint on. based on drying oils (flax, tung oil), pigments, desiccant solvents.

The positive quality of such paints. is a low solvent content of l. The disadvantage is low hardness, insufficient resistance to abrasion, low gloss, and unsatisfactory filling.

The closest to the technical I of the present invention is a floor paint based on a combined varnish K-5,

which is a mixture of sunflower and tung oils with SPP petroleum resin, desiccant, solvent (white spirit) and pigments 2.

Known paint also has insufficient hardness, water resistance, abrasion resistance, gloss.

The purpose of the invention is to increase the hardness reached, water resistance, resistance to wet abrasion, film gloss.

The goal is achieved by the fact that 5 paint for the floor, including the nave. thermal polymer resin, vegetable oil, pigments, desiccant and organic solvent, as vegetable oil contains oxidized vegetable oil and additionally a mixture of one-and-two-alcohols and dioxane and pyran esters, which are by-products; the product of the production of dimethyldioxane at, the following ratio of components. nanovy, wt.%:

As a petroleum resin, a product of thermal or catalytic polymerization of olefin-containing components of the pyrolysis resin is used (fraction 130-200 C).

a mixture of mono- and dihydric alcohols and dioxane and pyran ethers is obtained as a by-product of the production of dimethyldirk: I ::::::;: L :::: I;

Resin properties

Sanitary and commercially available under the name T-bb flotation agent (TU 38 103243-74); The product is a mobile liquid from yellow to brown in color with T kip. and is used as a surfactant. Mono- and dihydric alcohols and ethers of the dioxane and pyran series are represented mainly by the following components: trimethylcarbinol, 3-methylbutene-3-ol-1V 4, 4-dimethyl-5-methyloldioxan-1, 3; 2-methyl-4-tert-butoxybutanol-2; methyl tert-butyl ether-et al.).

Table 1 presents the characteristics of 5 petroleum resins used in the proposed composition.

Sample paint 1 is made on resin A / obtained from the fraction enriched in alicyclic fractions. Sample paint 2 is made on resin B obtained from the fraction.

Component Name Sample 1 j Sample Sunflower oil

Paints enriched with aromatic unsaturated compounds. Samples, paints 3 and 4 are made on resin B, obtained from a fraction containing: aromatic and alicyclic unsaturated hydrocarbons. The composition of paints is given in table 2. Table 2 2 Sample 3 Sample 4 The paint can be applied either by simple cold mixing of the oxidized vegetable oil with petroleum resin and subsequent dispersion of the pigment part, or by combining the pre-oxidized vegetable oil with the petroleum resin at 80-150 C.

The oxidized sunflower oil, the solvent (white spirit) is loaded into the mixer and, with the stirrer running, the petroleum resin is introduced in portions and mixed until the components are fully aligned. Then, the pigment part is introduced into the mixture and the T-bb flotation reagent (a mixture of alcohols and dioxane and pyran esters) and desiccant are loaded before dispersion. Dispersing is carried out in a bead mill until the desired degree of dispersion is achieved.

The paint can be prepared as follows.

A 70% solution preliminarily oxidized at a viscosity of 23 s according to VZ-4 is loaded into a mixer in white spirit sunflower oil, white spirit.

The mixture is heated to stirring, after which a petroleum resin is introduced in portions for 3 hours. After loading at the specified temperature, the mixture mixes with another 2 hours until the components are fully combined, Drying time at, 4 Film hardness after 72 hours (Film thickness 30-35 µm) Satisfied Blend Film Shine ..% Percentage of sediment,% after 24 h 120 h. Film durability to abrasion, kg / μm Water resistance for 20 min at 20 ° С Flexural strength according to SHG-1, mm Adhesion using a sieve method, fresh cut

The process of oxidizing sunflower oil is carried out in a heated oxidizer by blowing through a mass of air at 150-170 seconds. The oxidation depth is controlled by the viscosity of a 70% solution of oxidized oil in white spirit.

The dispersion of the pigment part is carried out in a 1.5 liter bead mill.

Ocher, zinc white, iron red pigment, yellow lead crowns, binder are loaded into a bead mill. A mixture of dioxane and pyran alcohols is served here and 800 g of grinding bodies are loaded with glass siberier with a diameter of 1.5-2mm):

Dispersing is carried out until a milling degree of 40 µm is achieved. Duration of dispersion is 40-45 minutes. When this degree of dispersion is achieved, the ink is transferred to a container equipped with a mechanical stirrer, where lead-manganese siccative is introduced 64.

After thorough mixing, the paint manufacturing process is considered complete.

Table 3 presents the comparative properties of floor paints according to the invention and known.

Thus, the floor paint according to the invention has improved physicomechanical properties as compared with the known, which allows expanding the scope of its application.
