摘　　要：考察了不同催化剂对双组分聚醚型聚氨酯防水涂料固化效果及固化后性能的影响。结果表明 ,有机金属类催化剂可用于催化本体系 ,而胺类的催化剂不合适 ;且综合而言 ,辛酸亚锡最为适合。The effects of different catalysts on the solidification and the mechanical properties of the casting film of two component polyether type polyurethane waterproof coating were investigated.The results show that the organometal catalysts are suitable for the polyurethane coatings,and the tertiary amine catalysts are not suitable.Stannous octoate is ideal for this system.
