RDX RDX PREPARATION METHOD FOR SUBMICRON AND MICRON SIZE- SPHERICAL RDX PARTICLES AND SPHERICAL RDX PARTICLES PREPARED BY THE SAME

摘要

The present invention relates to a method for manufacturing a submicron and micron-sized spherical RDX (cyclotrimethylene trinitramine) particle and a spherical RDX particle manufactured thereby. More specifically, the method for manufacturing the submicron and micron-sized spherical RDX particle comprises: a step for manufacturing an RDX solution by dissolving RDX in an organic solvent; a step for precipitating an RDX particle by mixing the RDX solution with an antisolvent; and a step for obtaining the precipitated RDX particle. Before the RDX solution and the antisolvent are mixed, a surfactant is added to the RDX solution or the antisolvent to be mixed. According to the present invention, a submicron and micron-sized spherical RDX particle is manufactured with productivity higher than that of a conventional method. In the case of a spherical shaped RDX particle, ignition pressure can be maximized due to increase in filling density and a relatively insensitive RDX particle can be manufactured due to a smooth surface. In addition, due to a size of a fine particle, an energy release rate is high, whereby it can be widely used as a civil and military composition such as high explosive gunpowder, a solid composite propellant, and the like.
