The embodiment of the invention provides a gas generating agent composition, a gas generating agent, a preparation method and application, and relates to the technical field of automobile safety air bags. The gas generating agent composition comprises guanidine nitrate serving as a fuel, basic copper nitrate serving as a main oxidizing agent, an auxiliary oxidizing agent and a slag forming agent; wherein the auxiliary oxidant is ammonium perchlorate. The slag forming agent is at least one zirconate, and the content of each component is as follows in percentage by mass: 40-60% of guanidine nitrate, 25%-50% of basic copper nitrate, 0.5%-7% of ammonium perchlorate, and 1%-10% of a slag forming agent; and the oxygen balance of the gas generating agent composition is 0 to -3%. According to the gas generating agent composition, the gas generating agent, the preparation method and the application, the content of toxic and harmful gas generated during combustion of the gas generating agent and the content of suspended solids in the air meet the limit requirements of USCAR on the content of the toxic and harmful gas and the content of the suspended solids in the air by adjusting the formula components and the proportion of the gas generating agent.

    本申请实施例提供一种气体发生剂组合物、气体发生剂及制备方法与应用,涉及汽车安全气囊技术领域。气体发生剂组合物包括作为燃料的硝酸胍、作为主氧化剂的碱式硝酸铜,以及辅助氧化剂和成渣剂,辅助氧化剂为高氯酸铵,成渣剂为至少一种锆酸盐,按质量百分数计,各组分的含量为:硝酸胍40%~60%;碱式硝酸铜25%~50%;高氯酸铵0.5%~7%;成渣剂1%~10%;气体发生剂组合物的氧平衡为0~‑3%。气体发生剂组合物、气体发生剂及制备方法与应用通过调整气体发生剂的配方组分及比例,以使其燃烧时生成的有毒有害气体含量及空气中悬浮物含量均满足USCAR对有毒有害气体含量及空气中悬浮物含量的限度要求。
