Abstract

The present invention relates to a preparation method of HMX / ANPyO eutectic under the confinement doping condition of a two-dimensional material. Triaminoguanidine nitrate (TAGN) is mixed with dimethyl sulfoxide (DMSO), and then HMX and ANPyO are added and waited for Dissolve completely, add glyoxal to obtain a two-dimensional conjugated structure material; grow HMX / ANPyO on this two-dimensional conjugated structure, and obtain HMX / ANPyO co-crystal under confined doping conditions. The method of the invention is simpler, the final material structure and performance can be precisely controlled through reaction conditions and doping amount, the product yield is high, the cost of raw materials used is low, and industrial production is easy to realize. Secondly, under the confinement doping conditions of two-dimensional materials, its crystal stiffness and molecular order packing density are improved, thereby improving its detonation performance. Finally, under the confinement doping conditions of 2D materials, HMX and ANPyO can form co-crystals in any ratio, and the experimental conditions are easy to control.

Description

technical field [0001] The invention belongs to the technical field of energetic materials, and relates to a preparation method of HMX / ANPyO eutectic under the condition of confined doping of two-dimensional materials. Background technique [0002] Low-fragility propellants show good stability against severe external stimuli such as heating, impact, and shock waves, and can greatly improve the battlefield survivability of combatants and weapons and equipment. There is an essential contradiction between the energy and safety of energetic materials, and the lack of high-energy insensitive energetic materials is the main bottleneck technology for the development of low-vulnerability propellants. [0003] Researchers continue to design and synthesize new energetic materials to obtain new high-energy insensitive explosives, such as 1,1-diamino-2,2-dinitropyrazine (FOX-7), 4,10-dinitro-2 ,6,8,12-tetraoxa-2,10-diazaisowurtzitane (TEX), 2,6-diamino-,3,5-dinitropyridine was also suc...
