Abstract
Using CL-20 as the main explosive, three types of acrylic rubber (ACM)(AR-71、AR-12、AR-14) and Estane 5703 as binder and dioctyl adipate (DOA) as plasticizer, the molecular dynamics simulation was conducted and then six kinds of CL-20-based PBXs were prepared by solution-water slurrying method and characterized by FE-SEM, XRD and DSC, and their impact sensitivities were tested.The results show that the plasticizer and ACM are coated on the surface of CL-20 crystal and the particles are spherical or ellipsoidal.CL-20 crystal is still ε type after being coated.The thermal stability of CL-20 is the best when CL-20 is coated by AR-71.The critical temperature of thermal explosion of CL-20 coated by AR-71 is 2.07℃ higher than that of CL-20 coated by Estane 5703.At the same time, the thermal stability of CL-20/AR-71 system is better than that of CL-20/AR-12 and CL-20/AR-14 in three types of CL-20 coated by the ACM.The binder AR-71 plays a very good role on reducing the sensitivity of CL-20.The introduction of plasticizer can effectively improve the thermal stability of CL-20/AR-71 and CL-20/Estane 5703 composite particles.The thermal stability and thermal safety of CL-20/AR-71/DOA system are the best, while the plasticizer also makes the mechanical sensitivity of CL-20/AR-71 and CL-20/Estane 5703 composite particles decrease.关键词
