水性聚氨酯的改性研究进展

Progress of the Modification Study on Waterborne Polyurethane

介绍了水性聚氨酯复合改性的几种方法和特点,其中包括用具有不同活性基团的有机硅改性、环氧树脂直接或间接改性、丙烯酸酯对水性聚氨酯的共聚改性、核壳结构乳液聚合改性、互穿网络法改性及其它改性。并指出了水性聚氨酯复合改性技术进一步发展的方向。

Several methods and characters of the modification of waterborne polyurethane were introduced in this paper. These methods included＇the modification of organ silicone with different active groups, the modification of epoxy resin, the modification of acrylate with copolymerization, core-shell type and interpenetration polymer networks. The development of this modification technology in the future was prospected.
