NITROGEN-GENERATING PYROTECHNICAL COMPOSITION Russian patent published in 2015 - IPC C06D5/06 C06B35/00 

FIELD: chemistry.

SUBSTANCE: invention relates to field of pyrotechnics, in particular, to pyrotechnical compositions, intended for obtaining low-temperature gaseous nitrogen in pressure containers, and can be used in automation systems, safety devices, for overflow of aggressive liquids, extinguishing 0f fires, preparation of respiratory mixtures, etc. Nitrogen-generating pyrotechnical composition contains, wt %: sodium azide - 85-91, copolymer of tetrafluoroethylene with vinylidenfluoride - 1-3 as oxidiser, and technical carbon with particle size 0.15-023 mcm - 8-12 as framework-forming substance.

EFFECT: increased volume of pure cold nitrogen output due to complete binding of metal sodium and optimisation of ratio of thermal base components oxidiser/fuel, with displacement towards fuel excess side, which extends technological possibilities of composition application.
