摘　　要：在最佳合成条件下,将自制的聚氨酯丙烯酸酯(PUA)低聚物作为基础树脂应用在紫外光固化涂料中,详细考察了低聚物、活性单体、引发剂对涂膜性能,主要包括附着力、硬度、耐冲击性、耐磨性、柔韧性、耐水煮性、耐腐蚀性的影响。在讨论了低聚物、活性单体、光引发剂对涂膜性能影响的基础上,通过大量实验,不断调整涂料配方,最终获得了适用于塑料基材、涂膜综合性能优良的涂料配方。In optimum synthesis conditions, the homemade PUA oligomer was used as a base resin in UV-curable coatings. The influence of the oligomer, reactive monomers and ini- tiator on the film properties, including adhesion, hardness, impact strength, abrasion resist- ance, flexibility, resistance to boiling, and corrosion resistance was investigated in detail, on which the coating formulations were adjusted through a large number of experiments, to find the final formulation that could be applied on plastic substrates with an excellent performance.
