Abstract

The invention discloses a high-energy density explosive compound and a preparation method thereof. The preparation method comprises the following steps: mechanically activating aluminum powder, polytetrafluoroethylene and nano copper oxide into high-energy ternary composite particles through high-energy ball milling process; reducing the diffusion distance between aluminum powder, and polytetrafluoroethylene and copper oxide, shearing and mixing with a single-compound explosive to enhance the reaction activity and completeness of the explosive, nano copper oxide, aluminum powder and polytetrafluoroethylene, and finally adding an adhesive and a desensitizer for kneading to form the high-energy-density explosive compound. The explosive compound disclosed by the invention is prepared from thefollowing components by mass: 14.8 to 28.8% of hexanitrohexaazaisowurtzitane; 42%-50% of spherical aluminum powder; 18-22% of polytetrafluoroethylene; 10-12% of nano copper oxide; 1-2% of butadiene rubber; and 0.1-0.2% of graphite. The explosive compound is suitable for explosive charging of an ultrahigh-speed warhead and a penetration warhead.

Description

technical field [0001] The invention relates to a high-energy-density explosive compound and a preparation method thereof, which are suitable for penetrating warhead charges. Background technique [0002] In recent years, with the modern complex combat environment, countries around the world have highly recognized the importance of solid defense targets for protecting important strategic facilities, and related protection technologies are constantly being updated and developed. It will be further strengthened, and the overall development will show a trend of strengthening, deepening, and large-scale overall structure. The penetrating warhead is an effective means of attacking solid defense targets. In order to achieve the requirements of damage and strike, the research and development of "high-density and high-energy explosive technology" is the goal that all countries have been pursuing, and it has become one of the cores of the development of a new generation of penetratin...
