The invention relates to a pyrotechnic solid substance for generating gas, a pyrotechnic composition and a gas generator, comprising an effective composition, the effective composition comprising, by weight, 40%-50% of guanidine nitrate, 6%-48% of basic copper nitrate, 1%-5% of alumina and 5%-15% of at least one coolant prepared from hydrated oxalate, and the pyrotechnic solid substance does not contain a binder component. The pyrotechnic solid substance has the beneficial effects that the pyrotechnic solid substance capable of generating gas, which is composed of the effective compositions, has the characteristics of high gas production rate, high combustion rate, low combustion temperature, low pressure index, small toxicity of released gas and the like, and is particularly suitable for an in-vehicle safety airbag as a passenger protection system.

    本发明涉及的一种产生气体的烟火固体物质、烟火药剂和气体发生器,包括有效组合物,所述有效组合物以重量百分比表示,包括:40%‑50%的硝酸胍、6%‑48%的碱式硝酸铜、1%‑5%的氧化铝以及5%‑15%的至少一种由水合草酸盐制备而成的冷却剂,且所述烟火固体物质中不含粘结剂成分。本发明的有益之处在于:通过上述有效组合物组成的产生气体的烟火固体物质,具有产气量高、燃烧速率快、燃烧温度低、压力指数低且释放的气体毒性小等特点,特别适用于车内安全气囊,作为乘车人员保护系统。
