摘要
本文研究了预聚物－NCO含量、多元醇并用比、扩链剂种类和用量、预聚物制备方法对羟丁型、聚酯型浇注聚氨酯弹性体动态生热性的影响。
In this paper, authors studied the effects of free-NCO content in prepolymer, polyols blend ratio, variety and amount of chain extenders and synthesis mothod of prepolymer on dynamic heat bulid-up property of PU elastomer based on HTPB,polyester and mixtures of them.
