摘　　要：用热重-红外(TG-IR)研究了TATB基高聚物粘结炸药(PBX)与硬质聚氨酯泡沫塑料(RPUF)之间在线性升温过程中的相互作用。结果显示,接触体系释出的气相产物组分基本上是两种独立组分释出的总和,没有新的组分产生。用微热量仪得到了140℃下受热10 d内T AT B基PBX与硬质聚氨酯泡沫塑料及二者接触体系的热量变化曲线。用红外和X-射线光电子能谱表征了量热测试前后样品的表面结构和元素含量,显示接触后样品的表面结构和元素环境没有变化,表明TATB基PBX与聚氨酯泡沫塑料的相容性良好。The interaction of TATB based PBX with rigid polyurethane foam （RPUF） in the linear heating-up process was investigated by TG-IR. The results show that the gas phase products released from the contact system are basically sum of the gas phase products released from the two isolated compositions and no new gas products occur. The curves of change in heat output for TATB based PBX, rigid polyurethane foam（RPUF） and their contacted system during the aging by 140 ℃/10 d were obtained by a microcalorimeter. The surface structures and element contents of the samples before and after heated were characterized by IR and XPS, revealing that the surface structures and element surrounding of the samples before and after contacted do not change and TATB based PBX and polyurethane foam have good compatibility.
