| 摘 要： | 在丙烯酸环氧单酯中添加颜填料和稀释剂等配制紫外光一热固化体系，并配制丙烯酸环氧双酯光固化体系对比实验，用FT-IR表征光一热固化过程特征吸收峰的变化．通过改变稀释剂的种类及用量，研究其对光固化和光一热双重固化膜的收缩率、凝胶率、硬度、吸水率、水接触角和热稳定性的影响．测试结果表明：光一热固化膜凝胶率均超过97．25％，固化完全，与单纯的双酯光固化膜相比，光一热双重固化膜体积收缩率明显减小，均低于5．70％，光一热固化膜水接触角约60°，其硬度和热稳定性增强． |

| Abstract: | Pigments and active diluents are added to epoxy monoacrylate to make up UV-heat curable coatings and conduct the contrast experiment of UV curable coating of epoxy acrylate,in which the process of UV-heat cured was indicated by FT-IR measurements.The influence of types and contents of active diluents on shrinkage,gel-content,hardness,water absorption,water contact angle,and heat resistance of UV cured films and UV-heat cured films were discussed.The results showed that the UV-heat cured films were cured completely and gel-content of them were over 97.25%,the shrinkage of them were below 5.70%,lower than that of single UV cured films.The water contact angle of the UV-heat cured films were approximately 60 °,and hardness,water resistance and thermal stability of them were increased. |
