CS267656B1 - Waterproof heat insulating material and method of its preparation - Google Patents

Abstract

The waterproof thermal insulation material has a low bulk density, high compressive strength and a low coefficient of thermal conductivity. It contains 30-55% aqueous solution of sodium silicate and solid sodium silicate from 60 to 94%, borax from 1 to 20% and perlite from 5 to 20%. The method consists in the following: solid sodium silicate, borax and perlite (or other material containing amorphous silicon dioxide) are added to the aqueous solution of sodium silicate. It is heated to a temperature of 80 to 250°C in a water bath or in an autoclave until a homogeneous mixture with a water content of 15-60%. The obtained product is solidified at temperatures of 500 to 700°C in preheated metal molds coated with metal phosphate or in other closed spaces ensuring the external shapes of thermal insulation products. Heating is carried out in electric furnaces or in furnaces heated with liquid or gas fuel or in a high-frequency field. The finished products are cooled to a temperature of 20 to 50 °C and released.
