A kind of azide-based composite solid propellant containing combination stabilizer

Abstract

The invention relates to an azido composite solid propellant containing a combined stabilizer. The azido composite solid propellant is prepared from the following components in parts by weight: 7% to12.5% of adhesive, 11% to 18% of plasticizer, 10% to 73% of oxidant, 0% to 60% of energy-containing explosive, 5% to 19% of metal fuel, 0.5% to 1.0% of curing agent, 0.05% of curing catalyst, 0.3% to0.6% of stabilizer, 0.2% of bonding agent, and 0.05% to 0.1% of crosslinking agent. The azido composite solid propellant containing the combined stabilizer has the advantages that the storage propertyis good, and the change rate of mechanical property in the storage process is smaller than 20%.

Description

technical field

[0001] The invention belongs to the field of composite solid propellants, in particular to an azide-based composite solid propellant containing a combined stabilizer. Background technique

[0002] Energetic materials are the source of power and power of weapons, and the material basis for weapon systems to achieve long-range precision strikes and efficient damage. Among energetic materials, the most important use of polymers is as adhesives. Adhesive is an important part of energetic materials. It is the matrix and skeleton of energetic materials. Only other components can be bonded together, so that the energetic material maintains a certain geometric shape and good mechanical properties. In addition, it also provides C, H, O, N and other elements required for combustion of energetic materials at the same time, which has an important impact on the energy performance, combustion performance, and aging performance of energetic materials.
