EPDM对CL-20的包覆及表征OA北大核心CSCDCSTPCD
Coating of CL-20 by EPDM and Its Characterization
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40.7 cm,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 wa…查看全部>>
