Abstract
Provided are a gas generant composition, a preparation method, and a gas generator containing the composition. The gas generant composition includes components having the following contents, in percent by mass: 40% to 60% of guanidine nitrate, 25% to 50% of basic copper nitrate, 0% to 7% of ammonium perchlorate, 1% to 10% of a slag-forming agent, and 0.05% to 5% of a release agent/lubricant, the slag-forming agent is used as a form-retaining agent, so that the tablets can retain their form before combustion very well after combustion, thereby completely avoiding burning of an inflatable bag due to melting and splashing of the combusted tablets. Moreover, ammonium perchlorate is used as auxiliary oxidizers, thereby reducing the amount of basic cupric nitrate used and reducing molten copper residues. The gas generant composition is mainly used in a gas generator for vehicle airbag.
