THERMAL INSULATING MIXTURE Russian patent published in 2009 - IPC C04B28/26 C04B18/14 C04B14/10 C04B35/66 C04B111/40 

FIELD: chemistry.

SUBSTANCE: invention relates to construction materials and can be used for making products meant for thermal insulation of thermal furnace units and power equipment with operation temperature of up to 1150°C. The thermal insulating mixture, containing liquid glass, granulated blast furnace slag, Cambrian clay, crushed glass, shard, stone screening dust and dolomite, contains liquid glass of density 1.4-1.5 g/cm³, granulated blast furnace slag M_"кр"=2.0-2.8, Cambrian clay, crushed glass, shard , stone screening dust and dolomite in the following ratio of components, wt %: said liquid glass 30.5-37.0, said granulated blast furnace slag 45.0-48.0, Cambrian clay 12.7-15.0, crushed glass 0.7-0.9, shard 1.0-1.2, stone screening dust 1.8-2.2 and dolomite 1.8-2.2.

EFFECT: reduced thermal conduction while providing for strength sufficient for practical use.
