摘　　要：为获得性能更佳的钝感传爆药,以奥克托今(HMX)原料为基础,采用溶剂-非溶剂重结晶技术,并辅以超声喷雾工艺制备细化HMX,同时,通过试验方法制备以丙烯酸酯橡胶(ACM)、F_(2602)和Viton A等3种材料为黏结剂的包覆HMX,并分别测试分析其安全性。结果表明:经过细化后,HMX的热稳定性和热敏感性降低,而撞击安定性则明显提高。制备包覆HMX时,在黏结剂与原料配比相同条件下,其表观活化能和指前因子均大于细化样品,且ACM包覆HMX会使其热稳定性更好。结合热爆炸临界温度可知:在95∶5的配比下由ACM包覆的炸药性能更佳,而且经撞击感度测试发现其降感效果亦最明显。In order to obtain insensitive booster explosives with better performance,based on HMX raw materials,fine-grained HMX was prepared by using solvent-non-solvent recrystallization technology and ultrasonic spray technology.Meanwhile,coated HMX with acrylate rubber(ACM),F_(2602) and Viton A as binders was prepared by using the experiment method,and its safety was tested and analyzed.The results indicate that after refinement,the thermal stability and thermal sensitivity of HMX are reduced,while its impact stability are greatly improved.When coated HMX is prepared,its apparent activation energy and pre-exponential factors are greater than that of refined samples under the condition of the same ratio of binder and raw material,and moreover,HMX coated with ACM will result in better thermal stability.According to the critical temperature of thermal explosion,it can be concluded that explosives coated with ACM at the ratio of 95∶5 has the best performance,and impact sensitivity test also shows that ACM has the most obvious desensitization effect.
