以环氧大豆油丙烯酸酯为主体树脂,以钛白、铁红、炭黑作为颜填料,配制白、红、黑三种 UV 色漆,考察了四种单一光引发剂及其复配组合对涂膜硬度、附着力和甲乙酮浸泡质量损失率等性能的影响。 结果表明:在白色、红色、黑色体系中,分别以 Irgacure184 与 Irgacure819 质量比为 1 : 2 ,Irgacure184 与 Irgacure907 质量比为 4 : 1 ,以及 Irgacure184 ,Irgacure907 和 ITX 质量比为 1 : 4 : 1 ,为效果最好的引发剂组合。

The white, red and black UV paints were prepared by with epoxidized soybean oil acrylate resins as its main resin and the titanium dioxide, iron oxide red or carbon as its pigment respectively. The influences of kinds of photoinitiators,their compounding on the curing effect,hardness and adhension of the final coating films were studied. The results indicate that Irgacure 184 with respect to the mass ratio of 1 : 2 Irgacure 819 triggered effect is best in the white system and Irgacure 184 and Irgacure 907 mass ratio of 1 : 2 have a high initiator in the red system, Irgacure 184 and Irgacure 907 and ITX is 1 : 4 : 1 which is the best initiator composition in the black system.
