Title
(EN) GAS GENERANT COMPOSITIONS COMPRISING MELAMINE OXALATE FOR USE IN AUTOMOTIVE RESTRAINT DEVICES
(FR) COMPOSITIONS GÉNÉRATRICES DE GAZ COMPRENANT DE L'OXALATE DE MÉLAMINE DESTINÉES À ÊTRE UTILISÉES DANS DES DISPOSITIFS DE RETENUE POUR AUTOMOBILE
Abstract
(EN)
A gas generant composition for passive inflatable restraint systems (e.g., airbags) for automobiles is provided that comprises a melamine oxalate compound. The gas generant may be a cool burning gas generant composition that comprises a melamine oxalate compound, a co-fuel, such as guanidine nitrate, and an oxidizer, such as basic copper nitrate. The gas generant composition has advantageous combustion properties, including a maximum flame temperature at combustion (Tc) of ≤ about 1700K (1,427C), a linear burn rate of ≥ about 18 mm per second at a pressure of about 10 megapascals (MPa), a gas yield of the gas generant composition of ≥ about 5.7 moles/100 cm3?, and a linear burn rate pressure exponent of ≤ about 0.35.
(FR)
L'invention concerne une composition génératrice de gaz pour des systèmes de retenue gonflables passifs (par exemple, des airbags) pour automobiles, qui comprend un composé d'oxalate de mélamine. Le générateur de gaz peut être une composition génératrice de gaz à combustion froide qui comprend un composé oxalate de mélamine, un co-carburant, tel que du nitrate de guanidine, et un oxydant, tel que le nitrate basique de cuivre. La composition génératrice de gaz possède des propriétés de combustion avantageuses, comprenant une température de flamme maximale à la combustion (Tc) ≤ à environ 1700K (1.427C), un taux de combustion linéaire ≥ à environ 18 mm par seconde à une pression d'environ 10 mégapascals (MPa), un rendement en gaz de la composition de générateur de gaz ≥ à environ 5,7 moles/100 cm3, et un exposant de pression à taux de combustion linéaire ≤ à environ 0,35.
