Abstract

The invention relates to a DAF and DNP eutectic explosive and a preparation method thereof, in particular to a 3,4-diaminofurazan (DAF) and 3,4-dinitropyrazole (DNP) eutectic explosive and a preparation method thereof, and belongs to the field of energetic materials. The DAF / DNP eutectic explosive is prepared by taking DAF and DNP as raw materials and adopting a solvent evaporation method. Compared with DAF, the prepared DAF / DNP eutectic explosive has the advantages that the melting point is greatly reduced, the DAF / DNP eutectic explosive is more suitable for being used as a fusion casting matrix explosive; the crystal density is obviously improved by 6.1%; the detonation velocity is increased by 9.7%, and a good detonation performance is shown. The preparation conditions are mild, and theprocess is simple and easy to operate. The eutectic explosive is a novel high-energy low-sensitivity fusion casting matrix explosive and has a good application prospect.

Description

technical field

[0001] The invention relates to a 3,4-diaminofurazan (DAF) and 3,4-dinitropyrazole (DNP) eutectic explosive and a preparation method thereof, belonging to the technical field of energetic materials. Background technique

[0002] The current fused-cast matrix explosives have inherent defects, such as 2,4,6-trinitrotoluene (TNT) has low charge density, unsatisfactory detonation performance, and easy oil leakage during long-term storage; 3,4-Dinitrofurazanylfuroxan (DNTF) has a poor detonation performance; 3,4-Dinitrofurazanylfuroxan (DNTF) has a too high melting point and is volatile when preparing melting and casting drugs; 1,3,3-Trinitronitrogen The cost of heterocyclobutane (TNAZ) is too high to mass-produce; the synthesis route of 1-methyl-2,4,5-trinitroimidazole (MTNI) is cumbersome and the cost remains high. Traditional fused-cast matrix explosives can no longer meet the requirements of modern weapons for the performance of energetic materials. Therefor...
