THERMAL DECOMPOSTION OF 2, 4, 6, 8, 10, 12-HEXANITRO-2, 4, 6,.8, 10, 12-HEXAAZAISOWURTZITANE (CL-20) WITH HIGH ENERGY INGREDIENTS

摘要

Thermal decomposition characteristics and interaction of 2, 4, 6, 8, 10, 12-hexanitro-2, 4, 6, 8, 10, 12-hexaazaisowurtzitane (CL-20) with other high energy ingredients are investigated by differential scanning calorimetry (DSC)-thermogravimetry (TG). The results show that the starting decomposition temperature decreases and the height of exothermic peak increases than pure CL-20 or Glycidyl azide polymer (GAP) in CL-20/GAP. Furthermore, the decomposition temperature of these two materials can be effected by each other. The height of the exothermic peak of CL-20/GAP/NG/BTTN is higher than that of GAP/NG/BTTN. It means that the first exothermic peak is assigned to the breaking of O-NO2, N-NO2 and -N3, while the second one is caused by the oxidation of RCHO. The decomposition heat is improved whereas the decomposition temperature is decreased by the present of CL-20.
