摘要： A nonazide gas generant that may be used in an inflation device, such as a vehicle passenger restraint system, comprising a hydrated or anhydrous mixture of nonazide fuel, an oxidizer and a quantity of copper phthalocyanine, otherwise known as Monarch Blue and/or azodicarbonamidine dinitrate. Specifically, the nonazide gas generant composition of the present invention may include phase stabilized ammonium nitrate (PSAN), high bulk density nitroguanidine (HBNQ), one or more nonazide fuels, a quantity of copper phthalocyanine and/or azodicarbonamidine dinitrate and optionally a binder. The gas generant composition of the present invention is capable of self-sustained burning at low or ambient temperatures and pressures, important for use in dual stage "smart" inflator automotive passenger restraint systems, while exhibiting a relatively high gas volume to solid particulate ratio upon combustion at acceptable flame temperatures. The composition also exhibits a tailorable burning rate and properties to preclude catastrophic events during cook off tests.

摘要： A pyrotechnic gas generant composition includes a high oxygen balance compound or fuel, preferably, azodiformamidine dinitrate, which is the resulting reaction product of an aminoguanidine salt and nitric acid. Specifically, the high oxygen balance compound or fuel of the present invention is the resulting reaction product of aminoguanidine salts, such as aminoguanidine nitrate, aminoguanidine bicarbonate, or aminoguanidine sulfate with nitric acid. Preferably, the aminoguanidine salt is aminoguanidine bicarbonate. The resulting reaction product is a yellow precipitate that can be used alone, with or without oxidizers or other additives, for very rapid self-deflagration or in combination with oxidizers and additives. In each instance, the gas generant composition provides both high gas output and low production of solid combustion products. Further, the precipitant is relatively non-hygroscopic and has a high burn rate. The gas generating composition is useful as a gas generator for an air bag of an occupant restraint system for an automobile, gun propellants, inflation and expulsion devices, flotation devices, pyrotechnics, fire suppression devices and smokeless, reduced smoke and smokey rocket propellants.

摘要： Gas generative compositions especially useful in inflators for protective passive restraint devices (e.g., motor vehicle air bags, escape slide chutes, lift rafts, and the like) include a nitrogen-containing fuel and an oxidizer selected from copper (II) oxide (CuO), cupric nitrate, basic copper nitrate (Cu(NO.sub.3).sub.2.3Cu(OH.sub.2), strontium nitrate (Sr(NO.sub.3).sub.2) and mixtures thereof. Most preferably the nitrogen-containing fuel is azodicarbonamidine dinitrate (AZODN) and/or 2,4,6,8,10,12-hexanitro-2,4,6,8,10,12-hexaazaisowurtzitane (CL-20). The compositions of the present invention provide high burning rates with acceptable burning rate pressure exponents which allow their operation at lower pressures, thereby resulting in the use of less costly, lower weight, and lower strength materials for design and manufacture of the inflator pressure vessel.

摘要： Solid gas generant compositions produce low particulates (e.g., condensed ash) when ignited. The solid gas generant compositions most preferably include a nitramine, at least one oxidizer selected from nitrates of strontium or cerium, in admixture with or without potassium perchlorate, and a binder. Graphite may optionally be employed. The gas generant compositions are usefully employed in inflatable vehicle occupant passive restraint systems (e.g., air bag systems).

摘要： Multicomponent pyrotechnic gas generating compositions are provided which comprise a single or multiple nonazide fuel. The single and multiple fuels are selected from guanidine, azole, and other high nitrogen aliphatic, aromatic, and/or heterocyclic compounds. The fuels are blended with single and multiple oxidizers. Other materials are added to the compositions for processing, aiding ignition, enhancing ballistics, reducing particulates, and scavenging undesirable gaseous decomposition products. A significant amount of nontoxic gas is formed at acceptable flame temperatures when these compositions are combusted, which allow their use in automotive air bag safety systems.
