摘　　要：研究了不同颗粒形态的LLM-105对HMX的降感作用以及HMX/LLM-105基炸药配方用的黏结体系和钝感体系。设计出一种HMX/LLM-105配方,采用机械感度和冲击波感度以及板痕试验和圆筒试验对其安全性能和爆轰性能进行了测试。结果表明,LLM-105可作为含能钝感剂用于HMX基PBX炸药,该种含LLM-105的HMX基PBX爆速约8700m/s、爆压34GPa以上、比动能为1.560kJ/g,冲击波感度比JOB-9003炸药低10%,是一种新型的低感高能炸药。The desensitizing effect of morphology of LLM-105 particles on HMX was studied, and binder system and desensitizer system for formulation based on HMX and LLM-105 were selected. A formulation based on HMX and LLM-105 was designed. The safety of the new formulation was characterized with friction, impact sensitivity and shock sensitivity, and the plate dent test and cylinder test were conducted to characterize its performances. The results indicate that LLM-105 can be used in main charge as an energetic desensitizer. The HMX-based PBX containing LLM-105 has high energy which detonation velocity is above 8 700m/s and detonation pressure is more than 34 GPa, and specific dynamic energy is above 1. 560kJ/g, the shock sensitivity is ten percent less than that of JOB 9003 explosive. This formulation is a new style low sensitive high energy explosive.
