Title:
GAS GENERANT COMPOSITION FOR GAS ACTUATOR FOR ACTIVATING SAFETY DEVICE AND GAS GENERATOR FOR GAS ACTUATOR USING THE SAME
Document Type and Number:
WIPO Patent Application WO/2007/129611
Kind Code:
A1
Abstract:
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.
