Embodiment 1

[0029] At 20°C, add 20ml of ethyl acetate into a three-necked flask, then add 0.438g of CL-20 and 0.217g of MTNP under stirring, when CL-20 and MTNP are completely dissolved, filter to obtain a co-crystal solution. Put the co-crystal solution in the spray tank, then adjust the spray pressure to 0.15Mpa, open the valve and spray the co-crystal solution into non-solvent water, rapidly precipitate crystals, filter, and dry to obtain micron-sized CL-20 / MTNP co-crystal explosives. .

Embodiment 2

[0031] At 25°C, add 15ml of acetone into the three-necked flask, then add 0.438g of CL-20 and 0.217g of MTNP under stirring, when CL-20 and MTNP are completely dissolved, filter to obtain a co-crystal solution. Put the co-crystal solution in the spray tank, then adjust the spray pressure to 0.25Mpa, open the valve and spray the co-crystal solution into non-solvent water, rapidly precipitate crystals, filter, and dry to obtain micron-sized CL-20 / MTNP co-crystal explosives.

Embodiment 3

[0033] At 30°C, add 25ml of acetonitrile into a three-necked flask, and then add 0.438g of CL-20 and 0.217g of MTNP under stirring. When CL-20 and MTNP are completely dissolved, filter to obtain a co-crystal solution. Put the co-crystal solution in the spray tank, then adjust the spray pressure to 0.3Mpa, open the valve and spray the co-crystal solution into non-solvent water, rapidly precipitate crystals, filter, and dry to obtain micron-sized CL-20 / MTNP co-crystal explosives.

Abstract

The invention discloses a preparation method of a hexanitrohexaazaisowurtzitane and 1-methyl-3, 4, 5-trinitro pyrazole eutectic explosive. The method includes the steps of: 1. preparation of a CL-20 and MTNP co-crystallization solution; 2. preparation of a CL-20 / MTNP eutectic explosive: placing the CL-20 and MTNP co-crystallization solution in a jet tank, then adjusting the jet pressure to 0.1-0.5Mpa, opening a valve, jetting the co-crystallization solution into nonsolvent water, rapidly precipitating crystals, and conducting filtering and drying so as to obtain the CL-20 / MTNP eutectic explosive. The invention also provides a CL-20 / MTNP eutectic explosive. The CL-20 / MTNP eutecticccrystal prepared by the method provided by the invention has high energy density and low sensitivity, can be used as a main component of explosive formula, and has good application prospect in insensitive ammunitions.

Description

technical field [0001] The invention relates to the technical field of energetic materials, in particular to hexanitrohexaazaisowurtzitane (CL-20) and 1-methyl-3,4,5-trinitropyrazole (MTNP) eutectic explosive and its Preparation. Background technique [0002] As the energy source of weapon system, energetic materials are the key basic materials of national defense. However, the contradiction between energy and safety exists in energetic materials, which seriously restricts their development and application. People have been looking for energetic materials with high energy and low sensitivity, but no effective breakthrough has been made so far. Therefore, it is urgent to study new modification methods to reconcile the contradiction between energy and safety. [0003] The development of eutectic technology provides a new way to construct new energetic material molecules and regulate their properties. The formation of eutectic energetic materials can effectively adjust the ...
