Abstract

The invention discloses an aluminum-containing explosive composition, and aims to solve the problems of high mechanical sensitivity and low energy of a (C6H14N2)[NH4(ClO4)3] compound. The aluminum-containing explosive composition comprises (C6H14N2)[NH4(ClO4)3], ammonium perchlorate, glycidyl azide polymer energetic thermoplastic elastomer, aluminum powder, graphite and paraffin, and is relativelylow in mechanical sensitivity and high in explosion heat energy. The aluminum-containing explosive composition is mainly used for air blasting type weapon ammunition charging.

Description

technical field [0001] The invention relates to a mixed explosive, in particular to an aluminum-containing explosive composition, and the invention is suitable for air blasting weapon ammunition charge. Background technique [0002] (C 6 h 14 N 2 )[NH 4 (ClO 4 ) 3 ] is a perovskite compound that can be used as an energetic material in the field of explosives. Zhang Weixiong and others disclosed this compound in "Use of a Class of Compounds as Energetic Materials" (Patent No.: 201610665880.3, August 12, 2016, P16-18). The theoretical density of the compound (1.98g / cm 3 ) is higher than RDX, HMX, mechanical sensitivity is lower than RDX, HMX, CL-20 (impact sensitivity 28%, friction sensitivity 70%), oxygen balance (in terms of CO 2 According to the calculation, it is -27.87) more negative than RDX and HMX, the detonation heat (5691J / g) is higher than RDX, and the production cost is low. However, the application of this compound in this respect has never been seen in Ch...
