FIELD: chemistry.
SUBSTANCE: invention relates to foundry production. The heat insulation mixture contains the following, wt %: magnesium aluminosilicate binder 7-10, tripoli 8-12, low-decomposition peat 5-60, quartz sand - the balance.
EFFECT: combination of peat and tripoli in the heat insulation mixture improves strength properties, mouldability and heat insulation properties of the mixture and also reduces its susceptibility to crumbling.
