介绍了国内外对提高水性聚氨酯(WPU)粘接强度的研究现状。详细阐述了WPU的分子链结构、共聚改性[包括环氧树脂(EP)改性、丙烯酸酯改性和有机硅改性]等对WPU粘接强度的影响,并对WPU今后的发展方向进行了展望。
The research status of improving the bonding strength of waterborne polyurethane (WPU) at home and abroad is introduced. The molecular chain structure of WPU, copolymerization modification [including epoxy resin (EP) modification, acrylate modification and silicone modification] on the bonding strength of WPU were expounded in detail and the future development direction of WPU Looking forward.
