| Abstract: |
| In order to study the interaction between cyclotetramethyltetramethylnitramine (HMX) and 2,4, 6-trinitrotoluene (TNT), 2, 4-dinitroanisole (DNAN), 3, 4-dinitrofurazan oxyfurazan (DNTF) with low melting point and high volatile energetic materials. The compatibility and thermal stability of mixed explosive were studied by DPTA and DSC. The result is DPTA study showed that HMX was compatible with TNT/DNAN/DNTF, and the order of thermal stability was HMX/DNTF>HMX/ TNT>HMX/ DNAN, HMX interact with TNT and DNAN to a certain extent, which makes the mixture of HMX, TNT and DNAN become less stable. DSC method of sealed crucible showed that the order of thermal stability was DNTF<TNT<DNAN according to decomposition peak temperature. The order of thermal stability is HMX/TNT<HMX/DNAN<HMX/DNTF, which is consistent with the result of DPTA determination method.HMX has good compatibility with DNTF, but HMX becomes incompatible with TNT and DNAN under high temperature and pressure.In conclusion, HMX/DNTF has good thermal stability and good compatibility in high temperature and high pressure environment. When the main charge of fusion casting-based explosive is HMX, DNTF is more suitable to be used as melting material. HMX/TNT and HMX/DNAN have good thermal stability and compatibility at 100 ℃, but poor compatibility at high temperature and high pressure. |
