Abstract

The invention discloses a preparation method of submicron hexanitrohexaazaisowurtzitane in batch. The method comprises: adding a surfactant into water to prepare a surfactant solution, grading by using grinding ball mediums with different diameters, adding CL-20, the surfactant solution and the grinding ball mediums into grinding tanks, cooling, symmetrically putting the grinding tanks, fixing the grinding tanks onto a planet grinder for planet grinding, separating a grinded explosive suspension and the grinding ball mediums, performing solid-liquid separation for the explosive suspension, and drying to obtain the submicron CL-20. According to the preparation method provided by the invention, the CL-20 explosive, the surfactant solvent and the grinding ball mediums with different diameters are graded, and the planet grinder is used for repeated grinding. The prepared epsilon-CL-20 is uniform in powder particle size, smooth in particle surface, and regulatable in average particle size; during a preparation process, no organic solvent impurities are introduced, a post treatment is reduced , a total grinding time is 1-10 hours, and a grinding time is short. The method is suitable for production in batch.

Description

technical field

[0001] The invention belongs to the field of energetic materials, and in particular relates to a method for batch preparation of submicron hexanitrohexaazaisopentazane explosive with smooth particle surface and particle diameter below 1 μm. Background technique

[0002] Hexanitrohexaazaisopentazane (CL-20) is a new type of caged nitramine high energy density compound first discovered and synthesized by American A.T.Nielsen in 1987. It is the elemental substance with the highest energy that can be mass-produced so far Explosives, the energy output is 10% to 15% higher than that of HMX. Under normal temperature and pressure, CL-20 mainly has four crystal forms, namely α, β, γ and ε, among which ε has the highest density and the best thermal stability, and is the preferred crystal form in modern weapon design.

[0003] Studies have shown that after micronization of explosives, most of them show reduced mechanical sensitivity, increased short-pulse detonation se...
