<p>An airbag gas generator which can attain impact ignitability, combustion velocity and gas generation capacity comparable to those of sodium azide base gas generators and a relatively low combustion temperature while inhibiting NOx generation even when use is made of an organic amine which generates ammonia upon heat decomposition, such as azodicarbonamide. The generator comprises an organic amine, an oxidizing agent containing at least 50 wt.% of a nitrate salt and a silicone resin preferably in respective amounts of 20-50 wt.%, 40-70 wt.% and 2-20 wt.% in the form of granules or a shaped article with the silicone resin acting as a binder. Although NOx is generated when an organic amine which generates ammonia upon heat decomposition is oxidized with a conventional oxidizing agent, the use of a nitrate salt as a specific oxidizing agent serves to inhibit the generation of NOx. Since, however, the melting of the nitrate salt before ignition is an endothermic reaction, the silicone resin is added as the binder to compensate for the delay of the reaction, thereby inhibiting NOx generation and maintaining a suitable reaction velocity.</p> |
