Abstract

The invention discloses a high-power heat-resistant explosive, in order to solve the problem of (C 6 h 14 N 2 )[NH 4 (ClO 4 ) 3 ]-based mixed explosives have high mechanical sensitivity and poor formability. The present invention consists of (C 6 h 14 N 2 )[NH 4 (ClO 4 ) 3 ], triaminotrinitrobenzene, butyl acrylate-acrylonitrile copolymer, and graphite. The invention has low mechanical sensitivity, high relative molding density, high energy output, and the penetration of perforating bullets is increased by 6% to 12%. The invention is mainly used for the charge of petroleum perforating bombs.

Description

technical field [0001] The invention relates to a mixed explosive, especially a high-power heat-resistant explosive, which is suitable for the charge of petroleum perforating bullets. Background technique [0002] (C 6 h 14 N 2 )[NH 4 (ClO 4 ) 3 ] is a new type of perovskite compound, which 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 and HMX, the mechanical sensitivity is lower than RDX, HMX and CL-20 (28% impact sensitivity, 70% friction sensitivity), the detonation velocity is higher than RDX and HMX (theoretical detonation velocity is 9212m / s), and the decomposition temperature (404℃ ) is higher than RDX and HMX, and the production cost is low. It is a high-temperature-resistant compound and is expected to be used ...
