Flame extinguishing pyrotechnic and explosive composition
First Claim
1. A flame extinguishing pyrotechnic composition which flamelessly deflagrates to produce primarily nitrogen gas, carbon dioxide gas, and a fluoroolefin gas, the composition comprising:
- (a) an azido binder;
(b) an azido plasticizer;
(c) a high nitrogen content solid additive selected from the group consisting of;
Ammonium 5-Nitraminotetrazole, Triaminoguanidinium 5-Nitraminotetrazole, Guanylaminotetrazole Nitrate, Triaminoguanidinium Nitrate, 1,7-Diazido-2,4,6-Trinitrazaheptane, and Nitroguanidine; and
(d) a perfluorocarboxylic acid salt in a flame suppressing amount wherein components (a), (b), and (c) are employed in an amount sufficient to produce nitrogen gas, carbon dioxide gas, and the enthalpy needed to vaporize flame suppressing agent (d) to produce fluoroolefin gas.

Abstract
A flame extinguishing pyrotechnic which flamelessly deflagrates to producerimarily nitrogen, carbon dioxide, and a fluoroolefin. The flame extinguishing characteristic is achieved by reducing the content of oxygen proximate the deflagration as well as through the flame suppressing properties of particular fluoroolefins. The pyrotechnic composition contains an azido binder such as glycidyl azide polymer (GAP), an azido plasticizer, a solid tetrazole, and a perfluorocarboxylic acid salt. This composition is cured to a rubbery composite by the addition of an isocyanate.
