摘要
利用1-甲基-4,5-二硝基咪唑(4,5-MDNI)在水中不同温度下的熔化和凝固结晶,通过水悬浮分散包覆工艺将4,5-MDNI包覆在六硝基六氮杂异伍兹烷(CL-20)颗粒的表面,制得外层为4,5-MDNI、内层为CL-20的双层混合炸药;采用扫描电镜观察了包覆前后炸药的显微结构、撞击感度测试表明:包覆后含量为6%的4,5-MDNI可使CL-20撞击感度(2.5 kg落锤)爆炸百分数由100%降低到8%;并通过DSC-TG技术研究了双层混合炸药的相容性。
CL-20 was coated with a little 4,5-MDNI by melting,dispersion and cooling crystallization to CL-20 surface in water,a kind of double-deck composite explosive with low mechanical sensitivity,in which inside layer is CL-20 and outsider is 4,5-MDNI.Microscopic structures were analyzed by SEM with the variety of technical condition of coat.The impact sensitivity（2.5 kg）results show that the composite explosive reduce from 72% to 8% due to 6% of 4,5-MDNI coat.Compatibility of double layer composite explosive was studied by DSC-TG.
