Process for the manufacture of high performance gun propellants |
摘要 |
A process for manufacturing a high performance gun propellant containing an energetic thermoplastic elastomeric binder and a high-energy oxidizer is disclosed. The process includes preparing or obtaining a molding powder of the high-energy oxidizer particles coated with the energetic thermo-plastic elastomeric binder and extruding the molding powder into the desired gun propellant configuration. The high-energy oxidizer has a concentration in the range from 70% to 85%, by weight, and the energetic thermoplastic elastomeric binder has a concentration in the range from 15% to 30%, by weight. The molding powder has a particle size in the range from 200 mu to 2000 mu . Typical thermoplastic elastomeric binders include oxetane, oxirane, and nitramine backbone polymers, copolymers, and mixtures thereof. Typical high-energy oxidizers include nitramine oxidizers.
