摘要： 制备了含有纳米二氧化钛和纳米氧化锌的醇酸涂层。使用交流阻抗研究了对醇酸涂料耐腐蚀性能的影响。作为对比，也研究微米二氧化钛和微米氧化锌对醇酸涂料的耐腐蚀性的影响。实验发现，纳米二氧化钛可以改善醇酸涂料的耐腐蚀性能，同时也能改善涂料的硬度。在一个醇酸色漆体系中，改善耐腐蚀性的最佳的纳米二氧化钛的含量为1%。测试添加纳米级和微米级二氧化钛和氧化锌的醇酸涂料的粘度，探讨了粘度和耐腐蚀性能的关系。

Abstract: Alkyd coatings embedded with nano-TiO2 and nano-ZnO pigments were prepared. The effects of nano pigments on anticorrosion performance of alkyd coatings were investigated using electrochemical impedance spectrum (EIS). For the sake of comparison, the corrosion protection of alkyd coatings with conventional TiO2 and ZnO was also studied. It was found that nano-TiO2 pigment improved the corrosion resistance as well as the hardness of alkyd coatings. The optimal amount of nano-TiO2 in a colored coating for corrosion resistance was 1%. The viscosities of alkyd coatings with nanometer TiO2 and ZnO and conventional TiO2 and ZnO pigments were measured and the relation between viscosity and anticorrosion performance was discussed.
