摘　　要：设计合成了一种新型漆酚环氧丙烯酸酯光敏树脂,对产物的结构进行了表征。利用所合成的树脂制备光固化涂料,采用响应面分析法研究了各因素对光固化漆膜力学性能的影响,得出了漆膜硬度、附着力和耐冲击性的二次回归模型,并对漆膜的制备工艺进行了优化。结果表明:构建的响应面模型拟合精度较高。各主要因素对硬度影响顺序为:固化时间〉引发剂质量分数〉稀释剂质量分数;对附着力影响顺序为:稀释剂质量分数〉固化时间;对耐冲击性影响顺序为:固化时间〉稀释剂质量分数。为使漆膜获得优良力学性能.通过试验分析与验证,确定稀释剂质量分数22.58%、引发剂质量分数4.15%、固化时间120 s为适宜的漆膜制备工艺条件。A new type of urushiol epoxy acrylate photosensitive resin was designed and synthesized,and the structure of the product was characterized.The effects of various factors on the mechanical properties of UV curable films were studied by response surface methodology(RSM).A quadratic regression models was established,involved in the hardness,adhesion and impact strength of the films,also the preparation process of the coatings was optimized.The results showed that the fitting accuracy of response surface model was high.The order of the effects of main factors on hardness was as follows:curing time>initiator mass fraction>diluent mass fraction,and the order of the effects of main factors on adhesion was as follows:diluent mass fraction>curing time,while the order of the effects of main factors on impact strength was as follows:curing time>diluent mass fraction.In order to obtain excellent mechanical properties of the coatings film,through test and verification,the optimal preparation conditions was determined as diluent amount of 22.58%,initiator amount of 4.15%and curing time of 120 s.
