摘　　要：为防止改性双基推进剂在低温状态下出现“脱湿”现象,分别选用3种键合剂对黑索今进行表面包覆。应用光电子能谱分析仪(XPS)检测了包覆产物的元素含量,通过扫描电子显微镜(SEM)观察了包覆前后粒子的表观形貌。实验数据表明:键合剂可以成功包覆于黑索今颗粒表面;同时,对包覆样品的撞击感度和摩擦感度分别作了测试,结果发现包覆后RDX的撞击感度降低,对摩擦刺激的反应没有明显变化。In order to prevent the problems of ＂dewetting＂ in CMDB at low temperature, the coating effects on RDX particles by 3 different bonding agents were studied. The element content of coating particles was characterized by XPS, SEM was used to observe the changes between uncoated particles and coated particles. The testing data indicated that the bonding agent could coat in RDX. The impact sensitivity and friction sensitivity were tested also. The results showed that impact sensitivity of coated RDX was decreased and friction sensitivity of that didn＇t have obvious change.
