Embodiment 1

[0024] In the CL-20 / CBNT eutectic explosive of the present invention, the molar ratio of CL-20 to CBNT is 1:10.

[0025] Add 0.438g Cl-20 and 3.46g CBNT into 5mL DMSO, raise the temperature to 90°C, wait until the two raw materials are completely dissolved, cool down to 35°C, add 15ml of non-solvent water, stir for 0.5h after the addition, and then filter. The filter cake was washed once with 20 mL of water to obtain 3.5 g of CL-20 / CBNT eutectic explosive. The detonation velocity of the eutectic explosive is 9300m / s, and the impact sensitivity (H 50 ) is 35cm.

Embodiment 2

[0027] In the CL-20 / CBNT eutectic explosive of the present invention, the molar ratio of CL-20 to CBNT is 1:1.

[0028] Add 4.38g of Cl-20 and 3.46g of CBNT into 10mL of DMSO, raise the temperature to 80°C, wait until the two raw materials are completely dissolved, cool down to 25°C, add 35ml of non-solvent ethanol, stir for 0.5h after the addition, and then filter. The filter cake was washed once with 20 mL of water to obtain 7.05 g of CL-20 / CBNT eutectic explosive. The detonation velocity of this eutectic explosive is 9350m / s, and the impact sensitivity (H 50 ) is 28cm. Wherein the scanning electron microscope of raw material and this eutectic explosive is as figure 2 Shown; The infrared spectrum of the raw material and the eutectic explosive is as follows image 3 Shown; The powder diffraction of the raw material and the eutectic explosive is as follows Figure 4 Shown; The Raman spectrum of raw material and this eutectic explosive is as Figure 5 Shown; The thermal a...

Embodiment 3

[0031] In the CL-20 / CBNT eutectic explosive of the present invention, the molar ratio of CL-20 to CBNT is 2:1.

[0032] Add 4.38g Cl-20 and 1.73g CBNT into 10mL NMP, raise the temperature to 60°C, wait until the two raw materials are completely dissolved, cool down to 20°C and add 30ml non-solvent water and ethanol mixture (volume ratio is 1:1), Stir for 1 h after addition, then filter. The filter cake was washed once with 20 mL of water to obtain 5.50 g of CL-20 / CBNT eutectic explosive. The detonation velocity of this eutectic explosive is 9270m / s, and the impact sensitivity (H 50 ) is 15cm.

Abstract

The invention relates to CL-20 and CBNT eutectic explosive and a preparation method thereof, and belongs to the field of energetic materials. Hexanitrohexaazaisowurtzitane (CL-20) and 5,5'-nitrate amino-3,3'-bi-carbazole (CBNT) are used as raw materials; a solvent / nonsolvent method is used for preparing the CL-20 and CBNT eutectic explosive. The energy of the prepared CL-20 and CBNT eutectic explosive is equivalent to that of the CL-20; the sensitivity is greatly reduced through being compared with that of the CL-20; the manufacturing cost of the prepared CL-20 and CBNT eutectic explosive is lower than that of the CL-20; the preparation process is simple; the operation is convenient; the conditions are mild; the eutectic explosive is suitable for large-scale preparation. The eutectic explosive is novel high-energy low-sensitive explosive, can be used for manufacturing low-vulnerable cartridge and has good application prospects.

Description

technical field [0001] The invention relates to a high-energy and low-sensitivity eutectic explosive and a preparation method thereof, in particular to a CL-20 and CBNT eutectic explosive and a preparation method thereof, belonging to the field of energetic materials. Background technique [0002] With the continuous development of high technology and the increasingly complex battlefield environment, the requirements for ammunition and weapons in modern warfare are becoming more and more stringent. The warhead is not only required to have the characteristics of long range, high power, and high energy, but at the same time, in order to improve the survivability of one's own combatants, the ammunition system must have the characteristics of insensitivity (that is, insensitivity). Among them, insensitive explosives are the research focus and hotspot of energetic materials in the 21st century. The eutectic technology provides a new technical approach for the preparation of inse...
