Title:
GAS GENERATING AGENT COMPOSITION, GAS GENERATING AGENT, PREPARATION METHOD, AND USE
Document Type and Number:
WIPO Patent Application WO/2023/087570
Kind Code:
A1
Abstract:
Embodiments of the present disclosure provide a gas generating agent composition, a gas generating agent, a preparation method, and a use, and relate to the technical field of automobile airbags. The gas generating agent composition comprises guanidine nitrate that acts as fuel, basic copper nitrate that acts as a main oxidant, and an auxiliary oxidant and slagging agent; the auxiliary oxidant is ammonium perchlorate, and the slagging agent is at least one zirconate; in mass percentage, the content of each component is: 40%-60% of guanidine nitrate; 25%-50% of basic copper nitrate; 0.5%-7% of ammonium perchlorate; and 1%-10% of the slagging agent; the oxygen balance of the gas generating agent composition is 0 to -3%. In the gas generating agent composition, the gas generating agent, the preparation method and the use, by adjusting the formula components and proportion of the gas generating agent, the content of toxic and harmful gases and suspended solids in the air that are generated during combustion meet the limit requirements of USCAR for the content of toxic and harmful gases and suspended solids in the air.
