摘要
以一种N-羟烷基季铵碱为三聚反应催化剂，合成了以六亚甲基二异氰酸酯（HDI）三聚体为主要成分的多异氰酸酯固化剂。对合成条件进行了探讨。
A polyisocyanate curing agent, which is mainly composed ofhexamethylene diisocyanate (HDI ) trimer, was prepared- A N-hydroalkyl quaternaryammonium hydroxide was used as catalyst for the trimerization. The reaction conditionswere studied.
