Abstract
A gas generating composition is obtained in which an amount of a combustion residue based on a unit amount of a gas generated is reduced. A gas generating composition comprising nitroguanidine, guanidine nitrate or a mixture thereof as a fuel and further an oxidizing agent. The oxidizing agent is a perchloric acid salt, a nitric acid salt or a mixture thereof, and when the oxidizing agent is ammonium perchlorate, a chlorine neutralizer is further incorporated.
Claims8
An inflator system for an air bag system comprising a gas generating composition in the form of an extrusion-molded article, said gas generating composition comprising a blend of a fuel comprising nitroguanidine, guanidine nitrate, or a mixture thereof,
- an oxidizing agent comprising a mixture of potassium perchlorate and strontium nitrate, and
- a binder comprising sodium carboxymethylcellulose and Japanese acid clay,
- wherein said extrusion-molded gas generating article is produced by extrusion molding processing.
A gas generating method using a gas generated by burning a fuel, in which a gas generating composition comprising a fuel comprising nitroguanidine, guanidine nitrate, or a mixture thereof, an oxidizing agent comprising a mixture of potassium perchlorate and strontium nitrate, and a binder comprising sodium carboxymethylcellulose and Japanese acid clay is formed into a gas generating article by extrusion molding and subsequently employed as a fuel in an air bag system, thereby decreasing an amount of a combustion residue and improve a gas output.
