摘要
Abstract
Based on the high⁃strength,low burning rate performance requirements of hydroxy⁃terminated polybutadiene( HTPB) propellant,a new⁃style reinforced and low burning rate dual functional additives was designed and synthesized.Acrylic acid,hydroxy⁃ethyl acrylate,butyl acrylate and triethylamine were used as ingredients to synthesize a new type polyacrylic ester polymer.To prove the synthetic compounds were the designed target compounds,series of characterization were carried out for the structure. The syn⁃thetic target compounds were used to study the influence of additive on mechanical properties of the propellant substrate and the thermal decomposition of AP.The results show that the additives can obviously increase the crosslink density,which can significantly improve propellant substrate mechanical strength.The add of dual functional additives can make the high temperature stage decompo⁃sition of AP reach 380 ℃,which can obviously inhibit the thermal decomposition of AP,so as to reduce propellant burning rate.关键词
