摘　　要：CL-20与HMX形成共晶,在能量损失相对较小的前提下有利于降低CL-20的感度,是目前CL-20基共晶材料研究的热点之一。为了促进CL-20/HMX共晶在混合炸药中的应用,采用水悬浮法分别制备了含HMX、CL-20、CL-20/HMX共晶的混合炸药,测试了不同炸药配方的机械感度、密度和爆速。以炸药配方的爆速测试结果为基础,对Kamlet公式进行修正,通过修正Kamlet公式及Urizar公式分别计算了HMX、CL-20、CL-20/HMX共晶的标准生成焓和特征爆速。结果表明,三种混合炸药中,含CL-20/HMX共晶的混合炸药机械感度低于40%,爆速大于8800 m/s,综合性能最好;三种单质炸药中,CL-20/HMX共晶的标准生成焓和特征爆速计算值较大,分别为851 kJ/mol、9335 m/s。The co-crystal of CL-20 with HMX is beneficial to reduce the sensitivity of CL-20 under the premise of relatively small energy loss,which is one of the hot topics in the research of CL-20 based co-crystal materials.In order to promote the application of CL-20/HMX co-crystal in mixed explosives,the mixed explosives containing HMX,CL-20 and CL-20/HMX co-crystal were prepared by water suspension method.The mechanical sensitivity,density and detonation velocity of different explosive formulations were tested.Based on the detonation velocity test results of the explosive formula,the Kamlet formula was modified.Then the standard formation enthalpy and characteristic detonation velocity of HMX,CL-20 and CL-20/HMX co-crystal were calculated by modified Kamlet formula and modified Urizar formula.The results show that among the three types of mixed explosives,the mixed explosive containing CL-20/HMX co-crystal has the best comprehensive performance.Its mechanical sensitivity is less than 40%,and the detonation velocity is greater than 8800 m/s.Among the three types of elemental explosives,the standard formation enthalpy and characteristic detonation velocity of CL-20/HMX co-crystal are relatively large,which are 851 kJ/mol and 9335 m/s,respectively.
