摘　　要：用DSC-TG-FTIR(热红)联用研究了RDX/AP,HMX/AP,RDX/HMX和RDX/HMX/AP混合体系的热分解,测定和比较了它们的热分析特征量和分解气相产物。结果表明,AP与RDX和HMX之间存在强烈的相互作用,尤其是与后者的作用更强烈。在AP(不含碳)分解的温度区间,混合体系的分解也出现CO、CO2和CH2O等碳氧化物,说明体系中RDX和HMX分解的部分产物或残渣与AP同时分解。The thermal decomposition of RDX/AP, HMX/AP and RDX/HMX/AP mixed systems were investigated by DSC, TG-DTG and simultaneous DSC-TG-FTIR. The characteristic values of DSC and TG-DTG curves and the gas products of decomposition for the systems mixed with AP were measured and compared with those for RDX and HMX components and RDX/HMX system. The results show that there is a strong interreaction of AP with RDX and HMX, especially with HMX. The carbon oxides such as CO,CO2 and CH20 also appear in decomposition temperature range of AP that not contain carbon for the mixed systems, showing that the part products or residual of RDX and HMX decompositions are simultaneously decomposed with AP for these mixed systems.
