摘　　要：研究比较了纳米TiO2、纳米SiO2及其质量比11的混合物对以自制的LB-1、TG-3树脂为主要成膜物所制得的紫外光固化粉末涂料性能的影响.结果表明,纳米粒子的添加可提高漆膜的硬度、附着力、抗冲击强度,显著地改善漆膜的耐候性能,但同时会使漆膜的光泽度和鲜映性有不同程度的降低;纳米TiO2及纳米TiO2与纳米SiO2质量比为11的混合物的添加量分别为3.0%-5.0%、2.0%-4.0%的质量分数时,可制得综合性能理想的紫外光固化粉末涂料.The influence of nano- TiO2 and nano-SiO2 and theirs＇mixture of nano- TiO2 and nano- SiO2 in the mass ratio of 1 ： 1 on performance of UV-curing powder coatings which were prepared by using LB-1 and TG-3 resins as main membrane materials was studied. The results showed that the nano-particles can enhance hardness and adhering force and impact-resistance strength of painting membrane, and can improve remarkably weather-resistance property of painting membrane, and lightness and DOI of the painting membrane decline somewhat. Nano- TiO2 and the mixture of nano- TiO2 and nano- SiO2 in the mass ratio of 1 ： 1 are added in the mass ratio of 3.0% - 5.0% and 2.0% - 4.0%, respectively, the UVcuring powders with optimum comprehensive properties can be prepared.
