FIREPROOF COATING Russian patent published in 2009 - IPC B32B5/02 B32B5/06 B32B5/10 A62C2/00 B65D90/22 

FIELD: protective devices.

SUBSTANCE: proposed coating consists of heat-protection layers with a component with shape memory effect fixed between them, which has a convolute (curled) form under temperatures higher than the transition phase temperature and made in the form of fibres based on equiatomic titano-nickel alloy. The fibres are linked between themselves and fixed between the heat-protection layers of connective strands. The alloy of the fibres of the specified transition phase at a specified temperature in a chaotic convolute three-dimensional form is given. Heat-protection layer and connective strands are made from heat-resistant aramid composite.

EFFECT: neutralisation of hot spots without separating highly smoking and harmful products, possibility of multiple use.
