GAS-GENERATING AGENT COMPOSITION

摘要

Disclosed is a gas-generating agent composition in which the pressure index and the dependence of the burning rate on pressure are extremely low. The gas generating composition, which comprises a nitrogen-containing organic compound as fuel and an ammonium nitrate as an oxidizing agent, is characterized in that the ratio of the nitrogen-containing organic compound and the ammonium nitrate (former/latter; weight ratio) is no more than 35/65. In the gas-generating agent composition, a copper compound may be further combined in a ratio in the range of more than 0 parts by weight to 30 parts by weight per 100 parts by weight of the total amount of the nitrogen-containing organic compound and the ammonium nitrate. A basic copper nitrate is preferable as the aforementioned copper compound. Additionally, a guanidine derivative, particularly a guanidine nitrate, is preferable as the aforementioned nitrogen-containing organic compound.
