(54) METHOD OF OBTAINING A COMPOSITION FOR PROTECTIVE INSULATING COATING

I

The invention relates to methods for preparing paint formulations which, after being applied, make it possible to obtain roofing, waterproofing daonne and other coatings.

A method of preparing a composition for a protective insulating coating is known, which includes mixing chloroprene rubber with a vulcanizing agent, chemical plasticizer, stabilizer, softener and filler followed by dissolving the resulting mixture in an organic solvent 1 on rollers.

However, the method does not provide greater tensile strength and an increase in the adhesion of the protective insulation coating.

The purpose of the invention is to increase the tensile strength and increase the adhesion of the protective insulating coating.

The goal has been achieved in that according to the method of preparing the composition for an intrusive coating comprising stirring chloroprene rubber on rollers

with a vulcanizing agent, chemical plasticizer, stabilizer, softener and filler, followed by dissolving the mixture obtained in an organic solvent, an epoxy resin solution with an amine hardener is further prepared in an organic solvent, followed by aging to 1.5–2 times the viscosity increase, after that, the solutions of rubber and zpoxy resin are mixed at the ratio of the components of the composition, wt.%;

The paint composition is applied in different ways (spray paint, roller, brush). It dries within 16-24 hours and forms a coating with a thickness of 50-500 microns per layer (depending on the method of application).

In the examples, the epoxy resin and the mixture of ethylene polyamine are mixed and kept

Irn 25-30 ° to increase the viscosity, respectively, l, 5jl and 2.0 times, then mixed with rubber composition.

The properties of the adhesive coating of the proposed composition are given in the table. As can be seen from the table below, the tensile strength increases by about 5, and the adhesion is about 2.5 times.
