The present invention provides a gas generator propellant, in particular for airbags, which contains (A) at least one carbonate, hydrogen carbonate or nitrate of guanidine, aminoguanidine, diaminoguanidine or triaminoguanidine, (B) at least one alkali-metal or alkaline-earth-metal nitrate or ammonium nitrate as oxidizing agent, and (C) at least one carrier substance selected from silicon dioxide, alkali-metal silicates, alkaline-earth-metal silicates or aluminosilicates and/or at least one oxygen-supplying carrier substance selected from iron(III) oxide, cobalt oxides, manganese dioxide and copper(II) oxide to moderate burn-up and improve slag formation. This gas generator propellant has improved burn-up behaviour and slag formation.
Un combustible générateur de gaz, notamment pour sacs gonflables, contient (A) au moins un carbonate, carbonate d'hydrogène ou nitrate de guanidine, aminoguanidine, diaminoguanidine ou triaminoguanidine; (B) au moins un nitrate alcalin ou alcalino-terreux ou nitrate d'ammonium comme agent oxydant; et (C) au moins un support sélectionné parmi le dioxyde de silicium, les silicates alcalins, alcalino-terreux ou aluminosilicates, et/ou au moins un support qui fournit de l'oxygène sélectionné parmi l'oxyde ferrique, les oxydes de cobalt, le dioxyde de manganèse et l'oxyde cuivrique, afin de modérer la combustion et d'améliorer la formation de cendres. Ce combustible générateur de gaz a une combustion et une formation de cendres améliorées.
