A gas generating agent for an inflator is an explosive composition required for expanding an airbag to protect passengers when a car accident occurs. An electrical signal detected by a sensor due to a car crash may cause the ignition and combustion of an igniter, an ignition charge, and a gas generating agent of the inflator in order. Gases and a high-temperature melting compound generated by the combustion of the gas generating agent are cooled and filtered through a filter to expand the airbag. In order for the high-temperature melting compound to be effectively cooled and filtered through the filter, the high-temperature melting compound must be converted into slag. In the present invention, by converting the high-temperature melting compound into the slag by using zeolite [Na4Al4Si4O25H18] or dolomite [CaMg(CO3)2] as a slag forming agent, and allowing an amount of combustion residuals discharged into the interior of the airbag during the operation of the inflator to be equal to or less than 1g, which is a standard value specified in USCAR-24, damage to the airbag can be prevented and passengers can be effectively protected.
气体发生器的气体发生剂是一种爆炸性成分,用于在发生车祸时膨胀安全气囊以保护乘客。车祸导致的传感器检测到的电信号可依次点燃和燃烧气体发生器的点火器、点火炸药和气体发生剂。气体发生剂燃烧产生的气体和高温熔融化合物通过过滤器冷却和过滤,使安全气囊膨胀。为了使高温熔融化合物有效冷却并通过过滤器过滤,必须将高温熔融化合物转化为熔渣。在本发明中,通过使用沸石[Na4Al4Si4O25H18]或白云石[CaMg(CO3)2]作为熔渣形成剂,将高温熔融化合物转化为熔渣,并允许在气体发生器工作期间排入安全气囊内部的燃烧残余物量等于或小于 1g(这是 USCAR-24 中规定的标准值),可以防止安全气囊受损,并有效保护乘客。
