摘　　要：本文研究了燃速催化剂与固化催化剂的交叉作用.作为燃速催化剂的有机和无机铅盐都程度不同地催化端羟基聚醚(HTPE)与多异氰酸酯(PAPI)的固化反应.有机铝盐的催化活性优于无机铅盐.水杨酸铅((LS)和邻氨基苯甲酸铅(OAB-Pb)中的活泼氢不干扰固化反应的进行.这种交叉作用对于简化推进剂的制造工艺过程是有利的.A study on the cross action between burning rate and curing reaction catalysts is presented in this paper.All organic and inorganic lead salts catelyze to some extent the curing reaction of hydroxy-terminated polyethers (HTPE)with polyisocyanate(PAPI) .The catalytical activity of organic lead salts is better than that of inorganic lead salts,It appears that the active hydrogen in lead salicylate and lead o-amino benzoate does not interfere with the curing reaction. The cross action is useful for simplifying the propellant manufacturing process.
