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 effect of six kinds of additives on the sensitivity of RDX / PU under impact and the suppression of explosive reaction were studied, and the essence of the influence of additives on RDX explosion reaction under impact was analyzed. The effect of additives on the thermal decomposition of RDX was studied by differential thermal analysis. The results show that the additives can reduce the impact sensitivity of RDX / PU to varying degrees. The influence of additives on the pyrolytic properties of RDX is related to the impact sensitivity.
