| 摘 要： | 采用甲苯二异氰酸酯、聚丙二醇、二羟甲基丙酸和丙烯酸羟乙酯合成了水性紫外光固化聚氨酯丙烯酸酯树脂,并用高支化聚酯对其进行了改性,研究分析了影响树脂水溶性和感光性的各种因素。结果表明,树脂亲水性与亲水基团含量呈正比;以819-DW为光引发剂,质量分数为3%时,涂膜光固化速度最佳;经高支化聚酯改性后的涂膜的综合性能有了较大的提高,质量分数为10%时,涂膜的综合性能最佳。

| Abstract: | A waterborne UV-curable polyurethane acrylic resin has been synthesized from polypropylene glycol,toluene diisocyanate,dimethylol propionic acid and hydroxyethyl acrylate,and then modified with a hyperbranched polyester.The influence of the modification on the hydrophilic properties and photosensitive properties of the resin was investigated,and the overall performances of the resin before and after modification were compared.The results showed that the hydrophilic properties of the resin were proportional ... |
