摘　　要：将制得的纳米ZnO浓缩浆以不同的浓度添加到聚氨酯清漆中,从而制得改性聚氨酯涂料。通过SEM、EIS、金相显微镜和紫外可见分光光度计等研究了此涂层的性能。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能力都明显优于普通涂层,且其力学性能也有所提高。This paper is about the preparation of modified PU coatings through adding different concentration of nanometer ZnO concentrate into PU varnish. SEM, EIS, Metalloscope and UV-Vis Spectrophotometer are used to study the property of the film, showing that nanometer ZnO through ultrasonic oscillation is of good dispersion property, that the anticorrosion and UV resistance properties are superior to ordinary coatings and that, the mechanical property is also improved.
