RAW MIXTURE AND WAY OF PRODUCTION OF FOAMED SILICATE HEAT INSULATION MATERIAL Russian patent published in 2012 - IPC C04B28/26 C04B40/00 C04B111/27 

FIELD: production of building materials.

SUBSTANCE: invention refers to production of building materials, in particular to production of flameproof heat insulating plate materials. The raw mixture for production of foam silicate heat insulating material including liquid glass, microsilica, additionally contains a filler - basaltic flakes, mica or talc and silicone oil from the range of polyalkylene hydrid siloxane and/or polyalkylene siloxane with the following component ratio, weight %: microsilica 2-15, silicone oil 0,1-10, the mentioned filler 0-5, liquid glass the rest. The way of production of foam silicone material with the use of the above mentioned mixture includes mixing of the components, heating of the mixture at the temperature of 75-100°C until it gets thickened, its graining, drying of the obtained grains up to the moisture level of 30-38 % with subsequent high-temperature processing in the closed mould at 250-450°C within 30-40 min.

EFFECT: ensuring of the even texture, decrease of water absorption and increase of water resistance.
