3,4-双(4'-氨基呋咱基-3')氧化呋咱与其他含能材料的热分解特性研究

Thermal Decomposition Characteristics of 3,4-bis(4'-aminofurazano-3') Furoxan and Other Energetic Materials

采用DSC和PDSC方法研究了3,4-双(4'-氨基呋咱基-3')氧化呋咱(BAFF)与其他含能材料(NC、NC/NG、RDX、HMX和DNTF)热分解反应之间的相互作用;结果表明,在NC/BAFF和NC/NG/BAFF混合体系中,BAFF的固-液相转变可使NC、NC/NG的分解温度向低温移动,且NC和NC/NG的热分解产物能促进BAFF的热分解反应;RDX与BAFF可形成低共熔物,且RDX的热分解产物能促进BAFF的热分解反应;在HMX/BAFF混合体系中,BAFF的热分解产物可以促进HMX的热分解反应;在DNTF/BAFF混合体系中,DNTF的固-液相转变使BAFF的分解温度降低,且彼此的热分解反应之间有较强的相互促进作用。

The interactions of 3,4-bis （4′-aminofurazano-3′） furoxan （BAFF） and some energetic materials such as NC, NC/NG, RDX, HMX and DNTF were investigated by means of DSC and PDSC. The results showed that in NC/BAFF and NC/NG/BAFF mixed systems, the solid-liquid phase transfer of BAFF made the decomposition temperature of NC and NC/NG lower, and decomposed products of NC and NC/NG could promote the decomposition of BAFF. In BAFF/RDX mixed system, the two materials formed a eu- tectic phase, and decomposed products of RDX could also promote the decomposition of BAFF. In BAFF/ HMX mixture, the decomposition of BAFF could promote the decomposing action of HMX. In DNTF/ BAFF system, the solid-liquid phase transfer of DNTF made decomposition temperature of BAFF lower. Moreover, the decomposition of them could accelerate each other.
