摘要

A new insensitive booster explosive based on 2,6-diamino-3,5-dinitropyrazing-1-oxide (LLM-105) was prepared by a solvent-slurry process with ethylene propylene diene monomer (EPDM) as binder. SEM (scanning electron microscopy) was employed to characterize the morphology and particle size of LLM-105 and molding powder. The mechanical sensitivity, thermal sensitivity, shock wave sensitivity, and detonation velocity of the LLM-105/EPDM booster were also measured and analyzed. The results show that both mechanical sensitivity and thermal sensitivity of LLM-105/EPDM are much lower than that of conventional boosters, such as PBXN-5 and A5. Its shock wave sensitivity is also lower than that of PBXN-5 and PBXN-7. When the density of charge is 95% TMD, its theoretical and measured detonation velocities are 7858 m s~(-1) and 7640 m s~(-1) respectively. These combined properties suggested that LLM-105/ EPDM can be used as an insensitive booster.
