Abstract

The invention belongs to the field of energetic materials, and particularly relates to a CL-20 and DMMD eutectic explosive and a preparation method thereof. The CL-20 and DMMD eutectic explosive comprises the following raw materials: 1-3 mol of CL-20, 0.5-2 mol of DMMD and a solvent. The preparation method comprises the step of S1, under a 313 K constant-temperature water bath condition, dissolving 1-3 mol of CL-20 and 0.5-2 mol of DMMD in the solvent. The melting point of a CL-20 / DMMD eutectic crystal prepared through the method is increased by 120.9 DEG C compared with the melting point 59.9 DEG C of DMMD, and is increased by 21.5 DEG C compared with the melting point 159.3 DEG C of CL-20, so that the melting point of the eutectic is greatly increased. The temperature of a decomposition heat release peak of the CL-20 / DMMD eutectic is 240.1 DEG C and is increased by 3.5 DEG C compared with the decomposition heat release peak of CL-20, and the preparation conditions are mild, the process is simple, and the operation is convenient.

Description

technical field [0001] The invention relates to the technical field of energetic materials, in particular to a CL-20 and DMMD eutectic explosive and a preparation method thereof. Background technique [0002] The main application of co-crystal technology is in the field of drug co-crystal, materials, and optics. At present, new drugs developed by co-crystal technology have improved drug properties in many aspects and achieved good results. With the continuous development of eutectic technology, this technology is gradually applied to the field of energetic materials. Although the research of eutectic in the field of energetic materials has just started, there are still many gaps and deficiencies, but it has shown great potential and application value. Co-crystal technology is to combine two or more different types of molecules in the same crystal lattice through intermolecular non-covalent bonds to form multi-component molecular crystals with specific structures and propert...
