摘要
以CL-20为主体炸药、EPDM为黏结剂,采用水悬浮法制备了CL-20基PBX炸药,用SEM、XRD和FT-IR对产物进行了表征,并测试了其撞击感度和热安定性。结果表明,该包覆工艺可使EPDM成功地包覆在CL-20表面,在包覆过程中CL-20晶型没有发生变化。与原料CL-20相比,包覆样品的撞击感度明显降低,特性落高由15.9cm提高到40.7cm,热安定性更好。
CL-20 based PBX explosive was prepared by water slurry method using CL-20 as filler,and EPDM as binder.The coated samples were characterized by SEM,XRD and FT-IR,and its impact sensitivity and thermal stability were measured.The results showed that EPDM can coat on the CL-20 crystal surface successfully,and the crystalline polymorph of CL-20 didn′t change during the coating process.Compared with raw CL-20,the impact sensitivity of coated sample was reduced significantly.The characteristic drop height was increased from 15.9 cm to 40.7 cm.The thermal stability was better than raw CL-20.
