Abstract

The invention discloses a high polymer material for modifying an explosive, wherein the material is characterized in that the molecule contains a pyrrolidone group, and the material can be prepared bycarrying out copolymerizing vinyl pyrrolidone and other polymerization monomers or by carrying out self-homopolymerization, can be matched with epoxy resins, acrylic resins and other polymer resins so as to be used as a modification material for explosives, and can be mixed with explosives in a powder form, or mixed with explosives under a heating condition. The invention further discloses a method for modifying explosives by using the polymer modification material, wherein direct mixing or heating melting mixing can be performed, and a mass ratio of an explosive material to the modificationmaterial is any ratio. The invention further discloses a method for modifying an explosive, wherein the high polymer material is adopted as an additive, and is mixed with an explosive material so as to affect the performance of the explosive material, wherein the performances comprise: mechanical performance, color, compatibility with other components, deflagration performance and the like.

Description

technical field [0001] The invention belongs to the technical field of explosive modification, and relates to a polymer material used for explosive modification, a preparation method of the polymer material used for explosive modification, and a method for explosive modification. Background technique [0002] TNT explosive has already been widely used, but due to its own problems, such as the production of toxic waste, transportation, storage and stability in use, etc., people try to find his substitutes, such as 2,4-di Nitroanisole (DNAN), (DNTF) and the like. Casting explosives is one of their important applications, and it is also the most widely used military mixed explosive at present. The solid phase particles of high-energy explosives are added to the molten explosive matrix to form a flow state for casting mixed explosives. Because of its convenient loading and good performance, cast explosives are mostly used in shells, grenades, missile warheads, etc., and occupy ...
