PURPOSE: High density and high performance composite explosive powder using hexanitro hexaaza isowurtzitane(HNIW) and a method for manufacturing the same are provided to improve the performance of the explosive powder and alleviate the sensitivity to external impacts of the explosive powder by using HNIW, acrylate elastomeric copolymer, dioctyl adipate(DOA), and graphite. CONSTITUTION: High density and high performance composite explosive powder includes HNIW as molecular explosive powder, acrylate elastomeric copolymer as a binder, DOA as a plasticizer, and graphite as an additive. The contents of the HNIW, the acrylate elastomeric copolymer, the DOA, and the graphite are in a range between 92.0 and 94.0 weight%, between 1.5 and 2.0 weight%, between 4.5 and 5.5 weight%, and between 0.2 and 0.8 weight%, respectively. The molecular explosive powder includes Cl-1 and Cl-5 at the weight ratio of 2:1 to 4:1. A method for manufacturing the explosive powder includes the following: the acrylate elastomeric copolymer and the DOA are dissolved in a volatile organic solvent to form a polymer solution; the HNIW and the graphite is dispersed in water to form a dispersion solution; the polymer solution is mixed with the dispersion solution to form explosive powder particles; and the explosive powder particles are collected and dried. |
