Beschreibung
Zusammenfassung:	Disclosed is a gas generant composition for a gas actuator used for activating a safety device, which contains (A) a nitrogen-containing organic compound, (B) a metal nitrate and/or a perchlorate, (C) a water-soluble polymer binder, and (D) a magnetic material. When compared with the conventional gas generant compositions, this gas generant composition is excellent in combustibility under low pressure conditions and reduced in CO gas generation during combustion. In this gas generant composition, (D) the magnetic material is preferably composed of a magnetic iron oxide. It is also preferable that (A) the nitrogen-containing organic compound is composed of one or more substances selected from nitroguanidine, guanidine nitrate, bitetrazole, azobistetrazole and 5-aminotetrazole; (B) the metal nitrate is composed of a metal salt selected from alkali metals and alkaline earth metals, while the perchlorate is composed of ammonium perchlorate or potassium perchlorate; (C) the water-soluble polymer binder is composed of a mixture of hydroxypropyl methylcellulose (HPMC) and a polyacrylamide; and (D) the magnetic iron oxide has a spinel crystal structure.
