熔铸载体炸药的研究进展

As the most widely used military composite explosive, the performance of melt-cast explosives is closely related to the choice of carrier explosive. The current research advances of melt-cast explosives were reviewed. The physicochemical properties and detonation performances of 13 representative melt-cast carrier explosives (such as 2, 4, 6-trinitrotoluene (TNT), 2, 4-dinitroanisole (DNAN), etc) were discussed. The molecular structures, synthesis methods, physicochemical properties and detonation performances of 16 newly synthesized melt-cast explosives were introduced (such as bis(1, 2, 4-oxadiazole)bis(methylene) dinitrate (BOM), etc). Their advantages and shortcomings as melt-cast explosives were analyzed. The effects of different functional groups and molecular structures on the properties of the compounds were discussed. The future development direction of melt-cast carrier explosive is to understand the effects of molecular structure on performance of explosives, and to design and synthesize a series of new compounds with excellent comprehensive performance, in order to meet the application requirements of melt-cast explosives.
