摘　　要：针对丁羟推进剂高强度、低燃速的性能要求,设计合成了新型补强降速双效助剂。选用丙烯酸、丙烯酸羟乙酯、丙烯酸丁酯、三乙胺为原料,合成了新型聚丙烯酸酯聚合物,并对其结构进行了表征,证明所合成的化合物为设计目标化合物。利用所合成的目标化合物,研究了助剂对推进剂基体力学性能和AP热分解性能的影响。结果表明,该助剂可明显提高推进剂基体交联密度,从而达到提高推进剂基体力学性能的目的,助剂的加入可使AP的高温分解峰达到380℃,明显抑制AP热分解,可产生降低推进剂燃速的效果。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.
