摘要
Thermal decomposition study of diammonium 5,5′-bistetrazole-1,1′-diolate (ABTOX) was investigated by using DSC. The result showed that ABTOX is less thermal sensitive than TKX-50. The kinetic parameters ( E = 139.82 kJ mol −1 and lg A = 12.75 s −1 ) for thermal decomposition reaction of ABTOX were obtained. The compatibility of ABTOX with 1,3,5-trinitro-1,3,5-triazacyclohexane (RDX), 1,3,5,7-tetranitro-1,3,5,7-tetraazacyclooctane (HMX), 2,4,6,8,10,12-hexanitro-2,4,6,8,10,12-hexaza-isowurtzitane (CL-20), 3-nitro-1,2,4-triazol-5-one (NTO), 1,1-diamino-2,2-dinitroethene (FOX-7), 2,6-diamino-3,5-dinitropyrazine-1-oxide (LLM-105), aluminum powder (Al), Estane-TPU-5702 and two kinds of fluoropolymers (F-2311 and F-2603) were evaluated by using DSC. The results showed that CL-20/ABTOX, FOX-7/ABTOX and F-2603/ABTOX were exhibiting good compatibility and RDX/ABTOX and Al/ABTOX had moderate compatibility. In addition, the compatibility of ABTOX with Estane-TPU-5702 and F-2311 was not good. HMX/ABTOX, NTO/ABTOX and LLM-105/ABTOX had poor compatibility. Furthermore, the self-accelerating decomposition temperature was calculated to be 152 °C and 150 °C in commercial wooden and PE cylinder, respectively.
