| 摘 要： | 以LLM-105为主体炸药,EPDM(乙丙三元橡胶)为黏结剂,采用溶液-水悬浮法制备了LLM-105/EPDM造型粉,并将其压制成药柱.用SEM对包覆前后样品的形貌进行了表征,并对其机械感度、热分解特性、热安定性和爆速进行了测试和分析.结果表明,与LLM-105和其他传爆药相比,EPDM/LLM-105造型粉的机械感度有一定程度的降低,热稳定性显著提高;当传爆药柱的装药密度为1.518 g/cm~3时,爆速可达7915 m/s.

| Abstract: | Selecting EPDM(ethylene propylene diene monomer)as binder and 2,6-diamino-3,5-dinitropyrazine(LLM-105)as main explosive,the molding powders composed of EPDM and LLM-105 were prepared by solution-water suspension method and pressed into booster charges.SEM was employed to characterize the raw and coated sample,and the mechanical sensitivities,thermal decomposition characteristics,thermal stability and detonation velocity were measured and analyzed.The results show that compared with that of raw LLM-105 and t... |
