摘　　要：结合水性技术和紫外光固化技术,在聚氨酯预聚体末端引入季戊四醇三丙烯酸酯,合成了紫外光固化的水性聚氨酯丙烯酸酯树脂,提高了涂膜的交联密度,改善了涂膜的耐水性和机械强度等性能;并进一步研究了紫外光固化的水性聚氨酯丙烯酸酯树脂的合成条件与乳液稳定性以及涂膜性能之间的关系。The article combined the advantages of waterborne technology with UV technology to synthesize aseries of ultraviolet curable waterborne polyurethane acrylate resins containing terminal pentatry thritoltriacrylate. The property of the water resistance and mechanical was improved because of increased cross-linking density. The effects of the different conditions on resin water-soluble and performance of the filmwas investigated.
