Embodiment 1

[0027] At room temperature, add 50ml of absolute ethanol into a three-necked flask, add 0.1095g of CL-20, heat up to 20°C, stir and dissolve CL-20, then add 0.0543g of MTNP, when CL-20 and MTNP are completely dissolved, a co-crystal is obtained solution. Continue to stir the co-crystal solution at 20°C, and then adjust the stirring speed to 50 rpm. During the stirring process, the co-crystal begins to precipitate, and the solution becomes turbid. Filter and dry to obtain micron-sized CL-20 / MTNP co-crystal explosives.

Embodiment 2

[0029] At room temperature, add 70ml of absolute ethanol into a three-necked flask, add 0.2175g of CL-20, heat up to 35°C, stir and dissolve CL-20, then add 0.1085g of MTNP, when CL-20 and MTNP are completely dissolved, a co-crystal is obtained solution. Continue to stir the co-crystal solution at 35°C, and then adjust the stirring speed to 150 rpm. During the stirring process, the co-crystal begins to precipitate, and the solution becomes turbid. Filter and dry to obtain micron-sized CL-20 / MTNP co-crystal explosives.

Embodiment 3

[0031] At room temperature, add 100ml of absolute ethanol into a three-necked flask, add 0.438g of CL-20, heat up to 40°C, stir and dissolve CL-20, then add 0.217g of MTNP, when CL-20 and MTNP are completely dissolved, a co-crystal is obtained solution. Continue to stir the co-crystal solution at 40°C, and then adjust the stirring speed to 200 rpm. During the stirring process, the co-crystal begins to precipitate, and the solution becomes turbid. Filter and dry to obtain micron-sized CL-20 / MTNP co-crystal explosives.

[0032] Such as figure 2 As shown, according to another embodiment of the present invention, this embodiment discloses the CL-20 / MTNP eutectic explosive prepared by the rapid preparation method of the above-mentioned embodiment CL-20 and MTNP eutectic explosive. figure 2 The crystal morphology of the CL-20 / MTNP eutectic explosive of the present invention is shown. Depend on figure 2 It can be seen that the CL-20 / MTNP eutectic explosive in this example is i...

Abstract

The invention discloses a rapid preparation method of a CL-20 (hexanitrohexaazaisowurtzitane) and MTNP (1-methyl-3, 4, 5-trinitro pyrazole) eutectic explosive. The method includes the steps of: 1. preparation of CL-20 and MTNP co-crystallization solution: adding CL-20 into an ethanol solvent, raising the temperature to 20DEG C-40DEG C, performing stirring dissolving, then adding MTNP to obtain the co-crystallization solution; 2. rapid preparation of a CL-20 / MTNP eutectic explosive: further stirring the CL-20 and MTNP co-crystallization solution, adjusting the stirring speed to 50-200rpm, rapidly precipitating crystals during stirring, 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 preparation method provided by the invention has the characteristics of simple process, convenient operation and mild preparation conditions, and is suitable for expanded preparation of eutectic crystals.

Description

technical field [0001] The invention relates to the technical field of energetic materials, in particular to the rapid preparation of hexanitrohexaazaisowurtzitane (CL-20) and 1-methyl-3,4,5-trinitropyrazole (MTNP) eutectic explosive Preparation. Background technique [0002] Eutectic explosives have gradually become a new strategy for constructing new energetic materials and regulating their properties, and have attracted extensive attention from international researchers, and have become one of the hotspots and difficulties in today's international research. At present, the preparation of eutectic explosives mainly adopts the traditional solvent volatilization method, relying on the slow volatilization of the solvent to precipitate crystals. This method has a long preparation period, small magnitude, low efficiency and poor repeatability. In addition, as the amount of solvent increases, it takes longer and it is difficult to scale up the eutectic process. Therefore, the ...
