The effect of ligand bonding agent-603(LBA-603) on the impact sensitivity of sub-micron CL-20/LBA-603 system was studied using the drop hammer impact test of sub-micron CL-20 and sub-micron CL-20/LBA-603 system.The action mechanism of LBA-603 in the composite explosive was investigated.The results indicate that LBA-603 was precipitated on the surface of sub-micron CL-20 and sub-micron CL-20 was coated at the same time because of induction effect between LBA-603 and the group of-NO2 of sub-micron CL-20.LBA-6...
