Abstract
An ignition enhancer coating composition for pyrotechnic propellants comprised of about 60 to 95 wt. % of an inorganic oxidizer; about 5 to 20 wt. % of an oxygen-containing polymeric compound; about 0 to 10 wt. % polyethylene; about 0 to 10 wt. % of a transition-metal oxide; and about 0 to 5 wt. % carbon black. This invention also relates to a pyrotechnic propellant coated with said ignition enhancer composition.
Claims10
An ignition enhancer composition for pyrotechnic propellants which comprises;
- (a) about 60 to 95 weight percent of an inorganic oxidizer selected from the group consisting of sodium chlorate, potassium chlorate, sodium perchlorate and potassium chlorate;
- (b) about 5 to 20 weight percent of a combustible oxygen-containing polymeric compound selected from the group consisting of polyacetal resins and polyvinyl acetate resins;
- (c) about 3 to 7 weight percent of a transition metal oxide;
- (d) about 1 to 5 weight percent of a polyethylene resin having a particle size equal to or less than 150 microns;
- and
- (e) from 0 to 5 weight percent of carbon black, wherein all weight percents are based on the total weight of the composition.
A pyrotechnic propellant composition suitable for use in inflating an inflatable device, said composition normally possessing less than desirable ignition properties, said composition being coated with an ignition enhancer composition comprising:
- (a) about 60 to 95 weight percent of an inorganic oxidizer selected from the group consisting of sodium chlorate, potassium chlorate, sodium perchlorate and potassium chlorate;
- (b) about 5 to 20 weight percent of a combustible oxygen-containing polymeric compound selected from the group consisting of polyacetal resins and polyvinyl acetate resins;
- (c) about 3 to 7 weight percent of a transition metal oxide;
- (d) about 1 to 5 weight percent of a polyethylene resin having a particle size equal to or less than 150 microns;
- and
- (e) from 0 to 5 weight percent of carbon black, wherein all weight percents are based on the total weight of the composition.
