AMMONIUM NITRATE BASED SOLID-FUEL GAS-GENERATING COMPOSITION Russian patent published in 2011 - IPC C06B31/32 C06D5/06 

FIELD: chemistry.

SUBSTANCE: invention relates to gas-generating techniques, particularly to high-energy solid-fuel gas-generating compositions and can be used in different fire-extinguishing systems based on gas-generators, standalone systems for lifting sunken objects, airbags in cars and oil well stimulation systems. The solid-fuel gas-generating composition contains an oxidising agent, fuel-binder and an energy additive. The oxidising agent used is GV ammonium nitrate, the fuel-binder used is methylpolyvinyl tetrazole and the energy additive used is nitraminopropionitrile, with the content of components in wt %: 60-70 GV ammonium nitrate, 5-20 methylpolyvinyl tetrazole, 20-25 itraminopropionitrile.

EFFECT: composition does not contain toxic compounds in combustion products, has low sensitivity to detonation and mechanical action, high gas throughput with low temperature of combustion products, good inflammability of compositions with high rate of their combustion under normal conditions.
