摘要:
选用键合剂LBA-1和热塑性弹性体(TPE)对RDX进行表面包覆改性，并应用于CMDB推进剂中。采用扫描电子显微镜(SEM)表征了RDX包覆前后颗粒表面的变化情况，同时，分别测试了RDX包覆前后和制备的CMDB推进剂的摩擦感度和撞击感度，并且对含包覆RDX的CMDB推进剂的力学性能和燃烧性能进行了表征。结果表明，经包覆改性后降感效果均明显，其中键合剂包覆的RDX，摩擦感度降低了68%，对应的CMDB推进剂，摩擦感度降低了37.5%。两种材料包覆改性RDX对推进剂的力学性能均有明显的改善，其中经热塑性弹性体包覆改性后，RDX-CMDB推进剂的抗拉强度提高了4.72 MPa，延伸率提高了19.67%；对推进剂的燃烧性能有一定的影响。
Abstract:
RDX was surface coated and modified with bonding agent LBA-1and thermoplastic elastomer(TPE), and then was applied in the CMDB propellant. Scanning Electron Microscopy (SEM) was used to characterize the particle surface of RDX before and after coating.The friction and impact sensitivities of the RDX before and after coating and RDX-CMDB propellant were studied. Furthermore, the combustion and mechanical properties of the RDXCMDB propellant were characterized. The results show that, compared with the uncoated RDX, the friction sensitivity of the coated RDX with bonding agent and corresponding RDX-CMDB reduce by 68% and 37.5%, respectively. Whats more, surface coated RDX had a significant effect on the mechanical properties of the propellant.For example, the tensile strength and elongation of the RDXCMDB were increased by 4.72 MPa and 19.67%, respectively, after coating of RDX with thermoplastic elastomer; and RDX coated with these two materials also exhibited a certain effect on the combustion properties of the propellant.
