Description

. one

The invention relates to polymeric solution mixtures used in the manufacture of building materials and construction.

A polymeric solvent mixture is known that includes a polyester resin, a mineral filler, cobalt naphthenate, and various polymerization co-accelerators. Known compounds are characterized by a relatively long polymerization time, difficulty of work at low temperatures, low alkali resistance even in weak alkalis.

Closest to the invention in its technical essence and the achieved result is a polymer solution mixture comprising a polyester resin, a mineral filler, cobalt naphthenate, hyperises, and a polymerization co-accelerator - lead oxide 2.

The known polymer solution mixture polymerizes at extremely high temperatures, the polymerization time is relatively short; but it has low alkali resistance under conditions of medium alkali, as well as increased fire resistance.

The purpose of the invention is to increase the alkali resistance of the polymer-solvent mixture.

This is achieved by the fact that the polymer solution mixture contains as a co-solvent polymerization - a mixture of aluminum oxide and aluminum hydroxide in the following ratio of components, weight. h Polyether resin10

The filler, resin and components of the initiating system are placed in steel forks with thorough mixing with the addition of the next reagent and compacted at ambient temperature from + 2 + to -7 ° C. After curing, the finished products are removed from the mold. Examples of the composition of the polymeric solution used are shown in Tables 1 and 2.
