摘　　要：合成了一系列乳液型紫外光（UV）固化聚氨酯丙烯酸酯，针对其涂膜性能进行研究，考察了辐射时间、膜厚、光引发剂用量、分子结构等因素对涂膜性能的影响；通过对各种影响因素的研究，得到了具有优良的涂膜性能和装饰性的乳液型UV固化聚氨酯丙烯酸酯，附着力在0～1级，正反耐冲击性都在50cm以上，铅笔硬度可以达到3H以上。A series of waterborne UV- curable polyurethane acrylates were synthesized. Their coatings properties were investigated. The influences of radiation time, film thickness, photoinitiator dosage, molecular structure and other factors on the coating properties were discussed. Therefore a series of UV curable polyurethane acrylate emulsions with excellent mechanical properties and decorative effect. The crosshatch adhensions of the coatings were between 0 and 1. Impact strengths are above 50 cm. The pencil hardness of the coatings film are over 3H.
