摘　　要：研究了６种添加剂对黑索今／聚氨酯（ＲＤＸ／ＰＵ）在撞击作用下的感度影响和爆炸反应被抑制情况，分析了添加剂对撞击作用下ＲＤＸ爆炸反应传播影响的实质．用差热分析技术研究了添加剂对ＲＤＸ热分解性质的影响．结果表明添加剂可以不同程度地降低ＲＤＸ／ＰＵ的撞击感度；添加剂对ＲＤＸ热分解性质的影响与撞击感度之间有一定的关联．The influence of six additives on the impact sensitivity of polyurethanebonded RDX (RDX/PU),the explosion propagation under impact and the quantity of sample residue after reaction are studied. The formal kinetic parameters of thermal decomposition of RDX and additive mixtures are calculated using the data obtained from DTA The results show that additives can markedly desensitize RDX/PU,but in various degrees.The influence of additives on the decomposition of RDS is compared with role role of desensitization to RDX.Some correlation has been obtained.
