SU392037A1 - POLYMERCEMENT SOLUTION - Google Patents

Description

The invention relates to compositions of polymer solutions used, for example, for flooring.

A known polymer polymer solution is a solution that includes a polyvinyl acetate emulsion, a mineral filler, water, and Portland cement.

The purpose of the invention is the reduction of water conductivity, amelioration, increase in strength and resistance to abrasion and aggressive media.

This is achieved by the fact that the solution additionally contains the SCS-65 GP latex at the following components matching by weight. including:

Polyvinyl acetate emulsion 0.1-0.2 Nanofiller - quartz sand 1.5-2.5 Water 0.5-0.6

Portland Cement1

Latex SKS-65 GP0.01-0.02.

When using the proposed composition for arranging the floors of livestock breeding, it is envisaged to use lightweight thermal insulation materials such as expanded clay sand, slag, etc., as a filler.

The polyvinyl acetate emulsion used contains 50% solids, and the SCS-65 GP latex - 40% solids.

Example. The solution is prepared as follows. Separately in a concrete mixer

2

a mixture of Portland cement sand is prepared with thorough mixing, and in a separate container an aqueous solution of polyvinyl acetate emulsion is prepared, which is then poured into a concrete mixer and the whole mixture is not displaced for 3-5 minutes, after which latex is added to the mixture again; 2 minutes. P | M1 prepared solution is poured into the tank and taken to the place of work. The solution is put into the process at a temperature not lower than 5 ° C.

Polymer cement solution has the following H1, not physicomechanical properties (and 28-day old):

Subject of the Invention A polymer solution, for example, for a NOLOV device, comprising a polyethylene acetate emulsion, mineral aggregate, water and portland cement, which is different. By the fact that, in order to decrease water permeability, increase strength and resistance to abrasion and aggressive media, it additionally contains latex SKS-65 GP at 5 with the following ratio of components to weight. including: 4 Polyvinyl acetate emulsion 0.1-0.2. Filler - quartz sand 1.5-2.5 Water 0.5-0, In Portland cement 1 Latex SKS-B5 GP 0.01-0.02.
