GAS GENERATING AGENT COMPOSITION, PREPARATION METHOD, APPLICATION, AND GAS GENERATOR

摘要

The present invention relates to a gas generating agent composition, a preparation method, an application, and a gas generator. The composition comprises the following components in percentage by mass: 30%-60% of guanidine nitrate, 25%-58% of basic copper nitrate, 5.5%-10% of strontium titanate, and 0.6%-10% of talc powder. According to the gas generating agent composition, the strontium titanate and the talc powder are jointly used as a shape keeping agent, and achieve a synergistic effect, so that the shapes of tablets before combustion can be kept well after the tablets are combusted, and gas bags can be prevented from being burnt due to melting and splashing of the combusted tablets; the composition is prepared by a wet process; the preparation process is simple and easy to implement; the gas generating agent composition is mainly applied to gas generators for supplementary restraint systems of automobiles.
