The TATB/HMX cocrystal explosive was prepared by solvent-nonsolvent method under ultrasonic assistance. The influence factors for the forination of TATB/HMX cocrystal were studied. The theoretical density and detonation velocity of TATB/HMX cocrystal explosive were calculated. Its characterization and thermal analysis were carried out by scanning electron microscope (SEM), X-ray diffractometer (XRD) and differential scanning calorimetry (DSC), and its impact sensitivity was tested. The results show that the optimum process conditions of preparing TATB/HMX cocrystal are: [Emim]Ac/DMSO as composite solvent, feed ratio of TATB and HMX as 3:7, temperature as 80℃ and stirring rate as 500r/min. The results show that compared with the raw materials, the structure of TATB/HMX cocrystal molecules changes. The particle size is about 2μm and the morphology is hexagonal. The thermal stability of the cocrystal explosive is better than that of HMX. The characteristic drop height increases by 74cm compared with the raw HMX, revealing that the impact sensitivity is significantly reduced. Its theoretical density is 1.891g/cm3 and theoretical detonation velocity is 8.758km/s, showing that it has good detonation performance. © 2017, Editorial Board of Journal of Explosives & Propellants.
