摘　　要：介绍了乙烯-醋酸乙烯共聚物(EVA)的基本性能,研究了它作为RDX基钝感传爆药的粘结剂对撞击感度、冲击波感度和烤燃特性的影响,并与氟橡胶F2641进行了对比。结果表明,EVA可使RDX的撞击感度和冲击波感度显著下降,并可改善烤燃特性。In this paper, the basic properties of ethylene-vinyl acetate copolymers(EVA) are introduced. The influence of EVA on impact sensitivity, shock sensitivity and cookoff behavior of RDX-based insensitive booster compositions is studied and compared with fluorocarbon polymer F2641. Results showed that EVA can extramely decrease the impact sensitivity and shock sensitivity of RDX, and can improve the cookoff behavior.
