Abstract

The invention relates to HMX-based boraxal-containing explosive. The explosive is prepared from the following various ingredients in percentage by patent: 60-68% of HMX, 15-25% of B-A1 composite powder and 14-18% of bonding agent, wherein the mass ratio of powder B to powder Al in the B-A1 composite powder is 1:1. The explosive can be used as the main charge of high-strength and high-security ammunition.

Description

Technical field [0001] The invention relates to the field of energetic materials, in particular to an HMX-based boron-containing aluminum explosive with enhanced aftereffect function. Background technique [0002] The application of active metals in energetic materials can quickly and effectively improve its functional power and explosive power. In the past, the most researched was aluminum powder. The results of the study show that aluminum powder can effectively increase the energy of explosives and enhance the thermal effect of explosives. Many elements in the periodic table are combustible. Aluminum powder is not the material with the highest calorific value among metal combustibles. Boron powder has higher mass and volumetric heat of combustion than aluminum powder, but boron powder has a higher calorific value than aluminum powder. With high combustion temperature, the energy released by the oxidation of aluminum powder can increase the oxidation efficiency of boron powder...
