NON-REUSABLE THERMOSTABILISING MATERIAL Russian patent published in 2009 - IPC C09K5/02 

FIELD: chemistry.

SUBSTANCE: invention relates to non-reusable thermostabilising material, which consists of a mixture which contains water as an active component, and agar-agar as binder, benzoic acid and calcium sulphate semihydrate, with the following ratio of components, wt %: calcium sulphate semihydrate 31 to 40; agar-agar 5 to 8; benzoic acid 0.05 to 0.2; water - the rest; and layers of aerosil and sealant, deposited successively on the top surface of the said mixture in the following ratio, in mm: aerosol 0.2 to 1; sealant 0.4 to 1.

EFFECT: obtaining non-reusable thermostabilising material which can keep temperature of an electronic component at up to 150°C for a long period of time, where the said component can be a memory module for an on-board recorder of flight information from thermal effect of a low-temperature (260°C) flame, and prevention of dehydration during storage.
