    摘要: An improved thermally stable, storage stable gas generating composition characterized by both an increased burning rate and a decreased pressure exponent for producing a clean, nontoxic, substantially ash- and solids-free gas for inflating inflatable structures such as vehicle airbags is provided. Optimum combustion efficiencies and operating pressures are achieved in the improved gas generating composition by adding an effective amount of a copper or copper compound catalyst to a gas generating composition that is preferably a eutectic mixture or solid solution of ammonium nitrate, at least one highly oxygenated fuel, potassium or cesium perchlorate or nitrate and an optional binder.

    摘要: Gas generant compositions exhibit low autoignition temperatures. In preferred forms, the gas generant compositions include azobisformamidine dinitrate (AZODN) and a eutectic mixture (comelt) of silver nitrate and potassium nitrate. The comelt of silver nitrate and potassium nitrate is most preferably present in the formulations of the invention in an amount to achieve a low autoignition temperature of between about 140° C. (284° F.) to about 160° C. (320° F.). The compositions of the invention may include a variety of auxiliary components typically employed in conventional gas generant compositions for their intended purpose. For example, especially preferred formulations of the present invention will include a powdered metal or metal oxide as a combustion catalyst to speed the decomposition reaction and also as a combustion aid to facilitate the ignition of the primary propellant or gas generant.

    摘要: This invention relates to gas-generative compositions consisting essentially of ammonium perchlorate with a chlorine scavenger, such as strontium nitrate, barium nitrate, potassium nitrate, or lithium carbonate, the combination being present in an amount of about 30 to about 95% by weight, up to about 5% by weight of a binder, up to about 5% by weight of a burning rate catalyst, together with an organic fuel, such as guanidine nitrate. The fuel is in an amount complementary to the combined weight of ammonium perchlorate, burning rate catalyst, chlorine scavenger, and binder, at an oxidation ratio of 0.90 to 0.98. The invention also includes the method of inflating an inflatable device by generating gas employing the noted composition and a gas generator in which the gas-generative composition is that of the present invention.

    摘要: A eutectic solution of ammonium nitrate and either aminoguanidiine nitrate (AGN) or guanidine nitrate (AN) in the form of a present pellet is used to generate a particulate-free, non-toxic, odorless and colorless gas that is useful wherever an immediate source of such gas is required, such as the inflation of an occupant restraint air bag. The use of the material in the form of a eutectic totally eliminates pellet cracking. Moreover, the addition of a minor amount of potassium nitrate to the eutectic solution eliminates the ammonium nitrate phase change due to temperature cycling without adversely affecting the pressed pellets' freedom from cracking due to said temperature cycling.
