Abstract

The invention relates to a preparation method of a high-nitrogen modified ammonium nitrate explosive crystal doped with a 2D conjugated structure. The method comprises the following steps: a high-nitrogen amino compound and an organic solvent with high boiling point are mixed, then an ammonium nitrate explosive and an aldehyde compound are added, and a 2D conjugated structure material is obtained;the ammonium nitrate explosive grows on the 2D conjugated structure, and the insensitively modified ammonium nitrate explosive crystal is obtained. The method is simpler, structure and performance ofthe final material can be controlled precisely through reaction conditions and doping amount, product yield is high, cost of raw materials is lower, and industrial production is easy to realize. Further, HMX is higher in energy, so that energy density cannot be reduced substantially by doping of a small quantity of a high-nitrogen 2D material, instead, crystal rigidity and molecular organized bulk density are increased, and detonation performance of the explosive crystal is improved.

Description

technical field [0001] The invention belongs to the technical field of energetic materials, and relates to a preparation method of a high-nitrogen two-dimensional conjugated structure doped modified ammonium nitrate explosive crystal. Background technique [0002] Efficient damage capability and high survivability are the main goals pursued by modern weapons. To achieve these goals, energetic materials as weapon energy carriers must meet the requirements of high energy density, low vulnerability and environmental adaptability. Therefore, improving energy while ensuring safety has always been a major goal in the development of energetic materials. Continuously designing and synthesizing new energetic materials has become one of the main research topics of synthetic chemists. However, due to the constraints of cost, energy density and safety contradictions, new energetic materials have been unable to replace existing high-energy explosives such as Orc Tojin (HMX) or insensit...
