PRESSABLE PLASTIC BONDED EXPLOSIVE FORMULATION USING HYTEMP/DOA AS A BINDER ITS PREPARING METHOD

摘要

PURPOSE: Provided is a compressed complex gunpowder composition of which charging density is increased and which is insensitive to an external shock. CONSTITUTION: The compressed complex gun powder comprises: (i) 90-96 wt.% of raw material powder(H.M.X); (ii) 1-3 wt.% of acrylate elastic copolymer(HyTemp-4404) as a crosslinking monomer having reactive hydroxy group; and (iii) 3-9 wt.% of D.O.A. The method comprises steps of: (i) dissolving 15-20 wt.% of the acrylate elastic copolymer(HyTemp-4404) in ethyl acetate at a temperature of 50-60 deg.C to prepare a liquid polymer solution; (ii) dispersing 8.0-11.0 wt.% of H.M.X in water to prepare a slurry solution; and (iii) after injecting the polymer solution into the slurry solution at a temperature of 60-70 deg.C to form a granular body, distilling the granular body.
