Gas generator compositions
First Claim
1. A gas generator composition, comprising:
- a cellulose acetate acting as a deoxidized agent that generates a predetermined composition of gas upon being oxidized;
a perchlorate acting as an oxidizing agent, the mixture of said cellulose acetate and said perchlorate being the major ingredient of said gas generator composition; and
a metal oxide acting as a combustion temperature controller, said metal oxide being more than 5% by weight and not more than 40% by weight of said gas generator composition.

Abstract
A gas generator composition, primarily containing perchlorate and cellulose acetate is provided to generate a large amount of gas without forming any substantial amount of harmful carbon monoxide. A metal oxide is additionally incorporated in an amount of more than 5% by weight and not more than 40% by weight. For example, 50 to 87% by weight of potassium perchlorate and 8 to 26% by weight of cellulose acetate are incorporated in the composition. The gas generator composition contains 36% by weight or less of bitetrazole metal hydrate, preferably bitetrazole manganese dihydrate, since it forms no corrosive residue after burning. The composition contains a nonmetallic compound consisting at least of nitrogen and hydrogen and containing at least 11% by weight of nitrogen. As such compound, nitroguanidine, guanidine nitrate, etc. is employed. The compounds preferably contains 10 to 83% by weight of nitrogen. The compound is preferably incorporated in an amount of 10 to 45% by weight. The gas generator composition is molded into a desired form, such as pellet, rod and disc and loaded in the combustion chamber of a gas generator. The composition is ignited by firing an igniter and burned to generate a gas.
