The inventive coating composition for coating comprising,%: chlorosulphurized polyethylene 10,1-14, styrolene-indene resin 10,3-15,2, a mixture of 1-aminoethylaminomethyl-2-heptadecyl-2-imidazoline with monoamide oleic acid /Olaza"/ 0,06-0,14, tetraethylthiuram disulfide 0,03-0,07, filler 13-17,7, organic solvent - rest. table 2.

The invention relates to the paint industry, in particular to composite materials based on chlorosulfonated polyethylene coating, equipment, piping, structures, operated in atmospheric conditions, under ground, under water or when exposed to chemically aggressive substances.

Known enamel based on chlorosulfonated polyethylene, structuring agent, pigment and solvent [1]

However, the coatings obtained from this composition, easily destroyed under the influence of mechanical and atmospheric conditions.

The closest in-sulfirovaniu polyethylene, bitumen, filler, an organic solvent and a saturated solution of ferric chloride [2] Coverage on the basis of known composition though and have frost and heat resistance, however, their physico-mechanical properties and chemical resistance are low.

An object of the invention is to improve the weather resistance of coatings in aggressive environments, the improvement of physico-mechanical properties, as well as the reduction of the applied layer of the composition on a substrate.

The technical result is achieved by the fact that the anti-corrosion composition for coatings, including chlorosulphurized polyethylene, filler and an organic solvent, optionally contains styrolene-indene resin, Alisol", representing a mixture of 1-aminoethylaminomethyl-2-heptadecyl-2-imidazoline with monoamide oleic acid and tetraethylthiuram disulfide, in the following ratio, wt.

As styrolene-indene resin is used, the copolymer according to THE 14-6-89-73 representing records. As tetraethylthiuram disulfide-use powder white or yellow color, produced according to GOST 739-74. "Olaza" is methodoloy a mixture of 1-aminoethylaminomethyl-2-heptadecyl-2-imidazoline with monoamide oleic acid in a mass ratio (9:1), respectively, produced according to TU 6-01-03-72-87. In the song he performs as a corrosion inhibitor and hardener.

The composition was prepared as follows. Chlorosulphurized polyethylene is dissolved at 60oC in an organic solvent, thus obtaining a varnish 12-18% concentration. Separately prepare 10-50% solution "Olusola" and tetraethylthiuram disulfide in an organic solvent, in this case, "Olusola" take 2-2,5 h, 1 h of tetraethylthiuram disulfide.

Before applying the composition to the substrate in the lacquer on the basis of chlorosulfonated polyethylene is injected styrolene-infilterate disulfide with "Olusola in an organic solvent. The composition is thoroughly mixed to a homogeneous state. The viability of the finished composition up to 2 days. During this period, the composition can be applied to the surface either manually (by filling) and mechanically interlayer drying of the coating layers at a temperature of 15-20oC for 15-30 min and dried to a level III within 1.5-3 hours

The specific examples of the compositions shown in table.1;properties of coatings based on the proposed composition in the table.2.

Anticorrosive composition for coatings, including chlorosulphurized polyethylene, filler and an organic solvent, characterized in that it further comprises styrolene-indene resin, Alisol", representing a mixture of 1-aminoethylaminomethyl-2-heptadecyl-2-imidazoline with monoamide oleic acid and tetraethylthiuram disulfide, in the following ratio, wt.

Chlorosulphurized polyethylene 10,1 14,0

Styrolene-indene resin 10,3 15,2

Olaza 0,14 0,6

Tetraethylthiuram disulfide 0,03 0,07

FIELD: chemistry.

SUBSTANCE: invention pertains to obtaining coatings with disinfectant properties, meant for sanitising premises, equipment, preservation and disinfection of water, including drinking water. The method involves the following. First, a derivative of polyhexamethyleneguanidine is obtained in the form of a base or hydrophobic salt, for example, an oleate from polyhexamethyleneguanidine chloride. Further, a solution of the obtained derivative of polyhexamethyleneguanidine is prepared in water or organic solvent and a solution of hydrophobic film-forming polymer from a series of chlorosulfonated polyethylene, polytrichlorobutadiene in an organic solvent. The obtained solutions are mixed with formation of a film-forming interpolymer with defined ratios and concentration of the solutions. The film-forming interpolymer is deposited onto a prepared surface in form of a coating of at least three layers, and possibly in form of a composition with target additives. Each layer is dried in air and then undergoes final hardening. The hardened interpolymer (coating) should have mass ratios of the derivative of polyhexamethyleneguanidine and the hydrophobic polymer in the range of 7.5-45.0 and 55.0-92.5 respectively. An alternative to the method is depositing a coating of a film-forming interpolymer, also obtained by combining a derivative of polyhexamethyleneguanidine, possibly in form of a solution, with an epoxide compound, possibly combined with a hardener, and also possibly in form of a composition with target additives. After hardening of such a coating, the mass ratio of the derivative of polyhexamethyleneguanidine and the epoxide resin should be in the range of 32-34 and 66-68 respectively.

EFFECT: method allows for effective disinfection of premises, equipment, as well as decontamination of water using a non-toxic substance with prolonged effect.
