Abstract:

以硝化棉(NC)为粘结剂、黑索今(RDX)为主体炸药, 采用喷雾干燥法制备了RDX/NC超细复合含能微球, 采用扫描电子显微镜(SEM)、X射线衍射仪(XRD)、差示扫描量热法(DSC)对其进行了表征及热分析, 并与RDX原料进行了对比; 对喷雾干燥法细化的RDX/NC和RDX、水悬浮法包覆的RDX/NC、溶剂非溶剂法细化的RDX、RDX原料的撞击感度分别进行了测试。结果表明, RDX/NC复合含能粒子与RDX原料相比, 形貌从块状变为球形, 粒径从50~200 μm减小至0.5~7 μm, 晶型无变化, 但X射线衍射峰明显弱化, 活化能从200.11 kJ·mol-1降至186.87 kJ·mol-1, 热爆炸临界温度从504.98 K升至507.70 K。喷雾干燥细化、球形化和复合的RDX/NC球形粒子的撞击感度降低显著
