Abstract
The present invention relates to gas-generating pyrotechnic compositions. The compositions according to the invention contain a small amount of epoxy binder, stabilized ammonium nitrate, optionally potassium perchlorate or an organic oxidant containing nitrogen and, characteristically, a reactive organic nitrogen compound selected from nitroguanidine, guanidinium nitrate and oxamide. This reactive nitrogen compound may advantageously be combined with cupric oxide. The compositions according to the invention produce nitrogen-rich gases with very low levels of nitrogen oxides, and find their preferred application in the form of pellets as pyrotechnic charges in gas generators for pyrotechnic extinguishers, for devices designed to inflate external structures or for devices designed to protect the occupants of a motor vehicle.
