异氰脲酸酯固化剂的研究进展

The Development of Manufacture of Polyisocyanate Curing Agent

异氰脲酸酯广泛用作聚氨酯涂料的固化交联剂 ,以提高产品的耐腐蚀、耐辐射、热稳定等性能。作者从催化剂、聚合方式、阻聚与阻聚剂、游离单体含量控制等方面 ,综述了近 2 0年来国内外异氰脲酸酯固化剂的研究进展 。

In order to raise product performance such as abrasion resistance,proof radiation,heat stability and so on,polyisocyanate is applied extensively as a cross link curing agent for polyurethane paint.The development of manufucture of polyisocyanate curing agent in recent twenty years was reviewed,which are catalyst polymerization mode anti polymerization,anti polymerization agent,free monomer content control.The main difficulties in eleveloping national polyisocyanate curing agent were pointed out.
