摘　　要：将纳米ZnO浓缩浆以不同的浓度添加到丙烯酸聚氨酯清漆中,从而制得改性丙烯酸聚氨酯涂料;通过SEM,EIS,金相显微镜和紫外可见分光光度计等方法研究了涂层的性能.结果表明,通过超声波振荡的纳米ZnO分散效果较好,纳米复合涂层的防腐性和抗紫外线性能都明显优于普通涂层.The nano-ZnO concentrated slurry was added to acrylic polyurethane with different concentrations,and the modified acrlate coatings were prepared.The coating properties were studied by SEM,EIS,metallographic microscope and ultraviolet-visible spectroscopy.The results show that the nano-ZnO is dispersed well by the ultrasonic quiver,and corrosion resistance and UV of the nano-composite coating are better than these of the the normal coating.
