Embodiment 1

[0035] At 20°C, add 10ml of ethanol and 10ml of ethyl acetate into a three-necked flask, add a sufficient amount of CL-20, start stirring, dissolve, and filter to obtain a saturated CL-20 solution. Then add a sufficient amount of 1-AMTN to the above solution, stir, dissolve, and filter to obtain a saturated solution of CL-20 and 1-AMTN. Transfer the saturated solution of CL-20 and 1-AMTN to a beaker, and slowly volatilize the solvent in a thermostat at 20°C to precipitate crystals, filter and dry to obtain CL-20 / 1-AMTN eutectic explosive.

Embodiment 2

[0037] At 30°C, add 20ml of ethanol and 20ml of acetone into the three-necked flask, add enough CL-20, start stirring, dissolve and filter to obtain a saturated CL-20 solution. Then add a sufficient amount of 1-AMTN to the above solution, stir, dissolve, and filter to obtain a saturated solution of CL-20 and 1-AMTN. Transfer the saturated solution of CL-20 and 1-AMTN to a beaker, and slowly volatilize the solvent in a thermostat at 30°C to precipitate crystals, filter and dry to obtain CL-20 / 1-AMTN eutectic explosive.

Embodiment 3

[0039] At 40°C, add 50ml of ethanol and 50ml of acetonitrile into a three-necked flask, add a sufficient amount of CL-20, start stirring, dissolve, and filter to obtain a saturated CL-20 solution. Then add a sufficient amount of 1-AMTN to the above solution, stir, dissolve, and filter to obtain a saturated solution of CL-20 and 1-AMTN. Transfer the saturated solution of CL-20 and 1-AMTN to a beaker, and slowly volatilize the solvent in a thermostat at 50°C to precipitate crystals, filter and dry to obtain CL-20 / 1-AMTN eutectic explosive.

Abstract

The invention relates to a CL-20 and 1-AMTN eutectic explosive and a preparation method thereof, particularly relates to a hexanitrohexaazaisowurtzitane (CL-20) and 1-amino-3-methyl-1,2,3-triazole nitrate (1-AMTN) eutectic explosive and the preparation method thereof, and belongs to the field of energetic materials. The CL-20 and the 1-AMTN are used as raw materials to prepare the CL-20 / 1-AMTN eutectic explosive by a solvent evaporation method. The impact sensitivity of the CL-20 / 1-AMTN eutectic explosive is greatly reduced compared with CL-20, and the safety performance is greatly improved. Compared with 1-AMTN, the eutectic explosive has significantly improved crystal density and detonation velocity, and shows good detonation performance. The preparation condition is mild, the process issimple, and the operation is convenient. The eutectic explosive is a novel high-energy low-sensitivity explosive, can be used for manufacturing low vulnerable explosives and has good application prospects.

Description

technical field [0001] The invention relates to a CL-20 and 1-AMTN eutectic explosive and a preparation method thereof, in particular to hexanitrohexaazaisowurtzitane (CL-20) and 1-amino-3-methyl-1,2 , 3-triazole nitrate (1-AMTN) eutectic explosive and a preparation method thereof belong to the field of energetic materials. Background technique [0002] The density of hexanitrohexaazaisowurtzitane (HNIW or CL-20) is 2.04g / cm 3 , the theoretical detonation velocity is 9500m / s, and the detonation pressure is 43GPa. It is the single substance explosive with the highest energy so far, but its impact sensitivity is 4J and friction sensitivity is 48N, which are at a relatively high level. The increasingly severe modern battlefield environment puts forward higher requirements for the performance of weapons and ammunition, among which safety performance is the top priority, and the development of high-energy and low-sensitivity energetic materials has become the focus of current re...
