摘要
Abstract
TG and DSC were used to investigate the thermal behaviors of the RDX-based microcellular combustible materials.The exothermic reaction kinetics was studied by non-isothermal DSC.The Kissinger and Ozawa methods were applied to investigate the thermal decomposition kinetics of combustible materials.The compatibility between components was evaluated based on the Kissinger method.The evaluation of heat resistance and moisture absorption were conducted.The results show that the decomposition is viewed as a two-step reaction,the first stage is the endothermic melting reaction without mass loss,the second stage is the exothermic reaction with mass loss.The activation energy obtained by Kissinger and Ozawa methods is similar,and activation energies of combustible materials are lower than that of pure RDX.The compatibility between binders (PMMA and CA) and RDX is good,level 1.The critical temperature of thermal explosion is similar to RDX.Other characteristics of new microcellular combusitble materials are superior to the old ones.关键词
