摘　　要：设计了一种研究燃烧催化剂对 EMCDB推进剂交联固化反应催化作用的实验方法 ,比较了十多种铅盐、铜盐对交联固化反应催化活性的强弱 ,筛选出了可用作粒铸 EMCDB推进剂燃烧催化剂的铅盐、铜盐。实验结果表明 ,某些铅盐对交联固化反应有较强的催化加速作用 ,铜盐和炭黑对交联固化反应没有明显的催化加速作用 ,只有对交联固化反应催化加速作用很小的铅盐才能用作The experiment, applied to study the curing catalysis of combustion catalysis for polyurethane EMCDB propellant, was designed, the catalytic activity of eight Pb salts and four Cu salts was compared, the Pb salts and Cu-salts, which could be used as combustion catalyst ingredient of EMCDB propellant, were selected. Experimental results showed that some Pb salts had stronger catalytic activity to the cross linking reaction, almost all Cu salts and carbon black had no catalytic activity, only these Pb salts, which had weaker catalytic activity, could be used as the combustion catalyst ingredient of EMCDB propellant.
