ABSTRACT For developing a new explosive formulation, a compatibility of polymeric binder with energetic compound is of most important in the pre-formulation stage. In this article, differential scanning calorimetry (DSC) method, according to STANAG 4147, was used to examine compatibility of diglycidyl ether of bisphenol A (DGEBA) with selected explosive compounds especially 1,3,5-trinitro-1,3,5-triazinane (RDX), l,3,5,7-tetranitro-1,3,5,7-tetrazocine (HMX) and 2,4,6,8,10,12 hexanitrohexaazaisowurtzitane (CL-20). Furthermore, the thermal decomposition behavior of the binary mixture was also studied by thermogravimetry. Results show that the epoxy resin (ER) possessed a good compatibility with both HMX and CL-20, while it showed a bad compatibility with RDX, according to STATNG 4147. The kinetics for the thermal decomposition reaction was also investigated through the Kissinger method using peak temperature obtained from DSC curves at different heating rates. The apparent activation energy for the RDX/ER, HMX/ER and CL-20/ER samples was obtained around 273.9, 299.3 and 166.3 kJ mol−1 with pre-exponential factor (A) value of 1.8 × 1029, 1.9 × 1028 and 9.3 × 1016 s−1, respectively.

环氧树脂与某些含能化合物的相容性和热分解行为

摘要对于开发新的炸药配方，聚合物粘合剂与含能化合物的相容性在预配方阶段是最重要的。在这篇文章中，根据 STANAG 4147，差示扫描量热法 (DSC) 方法用于检查双酚 A 的二缩水甘油醚 (DGEBA) 与选定的爆炸性化合物，尤其是 1,3,5-trinitro-1,3,5-三嗪烷 (RDX)、1,3,5,7-四硝基-1,3,5,7-四唑辛 (HMX) 和 2,4,6,8,10,12 六硝基六氮杂异武兹烷 (CL-20)。此外，还通过热重法研究了二元混合物的热分解行为。结果表明，根据 STATNG 4147，环氧树脂 (ER) 与 HMX 和 CL-20 均具有良好的相容性，而与 RDX 的相容性较差。还通过 Kissinger 方法使用从不同加热速率下的 DSC 曲线获得的峰值温度研究了热分解反应的动力学。RDX/ER、HMX/ER 和 CL-20/ER 样品的表观活化能分别为 273.9、299.3 和 166.3 kJ mol-1，指数前因子 (A) 值为 1.8 × 1029、1.9 × 1028 和分别为 9.3 × 1016 s−1。
