FIELD: chemistry.
SUBSTANCE: invention relates to the industry of construction materials and specifically to compositions for producing heat insulating materials. The composition for producing heat insulating material which contains a silica-containing component - gaize or tripoli, or diatomite, sodium hydroxide and water, also contains pyrolysis soot from burning rubber tyres, filter sediment from sugar production and finely dispersed powder of scrap ceramic brick or expanded clay, with the following ratio of components in wt %: silica-containing component 32.0-43.0; sodium hydroxide 6.7-10.2, pyrolysis soot from burning rubber tyres 4.0-6.4, filter sediment from sugar production 5.0-10.3, finely dispersed powder of scrap ceramic brick or expanded clay 6.3-10.7, water - the rest.
EFFECT: low coefficient of heat conduction, average density and cost of the ready heat insulating material.
