GAS GENERANT COMPOSITIONS CONTAINING AMINE NITRATES PLUS BASIC COPPER (II) NITRATE AND/OR COBOLT (III) TRIAMMINE TRINITRATE

摘要

A gas generant composition comprises between about 30 andabout 85 wt.% of A) fuel, and between about 15 and about 70 wt%of B) oxidizer based on total weight of A) plus B). At leastabout 60 wt%, up to 100 wt% of the fuel A) comprises an nitratesalt of a polyamine of the general formula selected from thegroup consisting of:(I) ZHN-CO-NHZ,(II) (see fig.I),(III) ZHN-CO-NH-CO-NHZ,wherein in formulae (I) - (III) the Zs are the same or differentand are selected from H and NH2,(IV) C2-C3-alkyl diamine, and mixtures thereof.At least about 60 wt%, up to 100 wt% of the oxidizer B) comprisesbasic copper(II) nitrate, i.e. Cu(NO3)2~3Cu(OH)2 and/orcobalt(III)triammine trinitrate, i.e., Co(NH3)3~(NO3)3.
