摘要：

The decomposition temperatures of composite explosives (HMX+NOG2Tz) in different mass proportions were measured by differential scanning calorimetry (DSC). The detonation velocities of composite explosives were calculated by an empirical equation. The thermal behavior of the composite explosive 9# (80%HMX+20% NOG2Tz) was studied by DSC at different heating rates. The apparent activation energy and pre-exponential factor of the exothermic decomposition reaction, the temperature (Te0) of the extrapolated onset in heating rate β→0, and the critical temperature of thermal explosion (Tb) were calculated. The results show that the decomposition peak temperature of the composite explosive 9# increases by 2°C and the apparent activation energy by 70 kJ·mol-1over the pure HMX. It indicates that the addition of NOG2Tz (
