METHOD TO PRODUCE HEAT INSULATION AND INSULANT MATERIAL FOR BUILDING PRODUCTS Russian patent published in 2012 - IPC C04B28/26 C04B40/00 

FIELD: construction.

SUBSTANCE: method to produce heat insulation and insulant material for building products includes mixing of a binder based on amorphous silica with dispersion of 1-10 mm with loose heat insulation filler with dispersion of 0.5-15.0 mm for 3-10 minutes until a homogeneous dry mixture is produced, subsequent tempering of the dry mixture with an aqueous solution of an alkaline component during subsequent mixing for 1-5 minutes and subsequent moulding of products by method of their pressing with force of 5.0-10.2 kg/cm² with subsequent thermal treatment at 150-850°C. The other version of the method includes mixing of the binder with a loose heat insulation filler, introduction of an alkali-containing component into the mixture, subsequent mixing to produce a homogeneous mass and moulding of products by the method of semidry pressing.

EFFECT: production of ecologically pure material with good strength properties, lower heat conductivity, simplified process of production and reduced prime cost of a finished product.
