Abstract
A compactable composite explosive consisting of 90 weight % to 95 weight % of a raw explosive material being RDX, 5 weight % to 10 weight % of ethylene vinyl acetate copolymer resin containing vinyl acetate in a content of 10 % to 20 % and 0 weight % to 0.5 weight % of dioctyl adipate (D.O.A.) or graphite. This composite explosive is usable as a main charge or a booster of a highly precise arms system. The invention also provides a method for producing a compactable composite explosive, which comprises the steps of dissolving a binder of ethylene vinyl acetate copolymer resin in a solvent of toluene to prepare a solution, injecting the solution into RDX dispersed in a water, forming a granular product from the obtained mixture, distilling primarily the product, *adding toluene into the product, and distilling secondarily the product. The amount of added toluene is 1.0 time to 3.0 times the amount of the binder measured after the primary distillation. The grain size of a final product can be freely controlled according to the amount of added toluene.
