以CL-20为主体炸药、Estane5703为黏结剂、硬脂酸钙（CaSt2）为增塑剂，采用水悬浮法制备了4种复合粒子。用SEM、XRD、DSC对目标产物进行了表征及性能测试。结果表明，水悬浮法可以使硬脂酸钙和 Estane5703成功包覆在CL-20晶体的表面，CL-20的晶型仍为ε型，说明硬脂酸钙不会改变CL-20主体炸药的晶型。加入硬脂酸钙后，CL-20／Estane复合粒子的特性落高从34．8 cm升至39．8 cm，热稳定性有所改善；当硬脂酸钙的质量分数为0．5％时，CL-20／Estane包覆样品的热爆炸临界温度提高了5．81℃。

Four kinds of composite particles were prepared by water slurry method using CL-20 as filler,Estane5703 as binder and calcium stearate(CaSt2 )as plasticizer.The CL-20/Estene/CaSt2 composite explosive was characterized by SEM,XRD and DSC.The results show that the CaSt2 and Estane5703 can coat CL-20 successfully,the crystal type of CL-20 was stillε,showing that the CaSt2 can′t change the crystal type of CL-20 main explosive.Compared with CL-20/Estane5703,the characteristic drop height of CL-20/Extane/CaSt2 composite explosive was increased from 34.8 cm to 39.8 cm and the thermal stability improved.The thermal explosion critical tempertature increased by 5 .8 1℃ when the content of CaSt2 was 0 .5%.
