Hydroxylammonium nitrate/water/self-deflagrating fuels as gas generating pyrotechnics for use in automotive passive restraint systems

摘要

Liquid gas generant compositions are aqueous solutions of hydroxylammonium nitrate as the oxidizer and a fuel selected from the group consisting of nitrate salts of amines of the formulae:P PA.sup.1) an amino tetrazole or amino triazole,PPA. sup.2) an amine of the formulae (I) (NHZ).sub.2 --C═O, (II) (NHZ). sub. 2 --C═NZ, (III) HN--(CO--NHZ).sub.2, where the Zs are the same or different and are selected from H and NH.sub.2,PPA.sup. 3) C.sub.2 -C.sub.3 -alkyldiamine, andPPmixtures of the nitrate salts of amines of the above formulae.
