THERMOSTABILISING MATERIAL OF ONE-TIME ACTION Russian patent published in 2008 - IPC C09K5/02 

FIELD: chemistry.

SUBSTANCE: thermostabilising material of one-time action is proposed, consisting of inner and outer layers in proportion 10:1 by weight. Inner layer contains malonic acid as an active component with decomposition endothermic effect, boric anhydride as catalyst, boron nitride, and ethylsilicate in proportion as follows, in wt %: malonic acid 80-85, boric anhydride 8-10, boron nitride 2-3, ethylsilicate the rest. Outer layer contains lithium carbonate and ethylsilicate, in proportion as follows, in wt %: lithium carbonate 80-85, ethylsilicate the rest.

EFFECT: widening of thermostabilisation range at expense of heat storage material, combining endothermic effect of melting and endothermic effect of decomposition.
