纳米改性聚氨酯涂料在海洋大气及飞溅区的应用研究

摘要

This paper introduces the preparation of nano zinc oxide putty and nano modification PU coatings.This paper introduces the analysis of the corrosion resistance and weatherability of nano modification PU coatings for the use in marine atmosphere and splash zone through SEM,EIS,glossiness instrument and surface contact angle meter;discusses the modifying effect of nano zinc oxide on the property of PU coatings.Experiment result shows that suitable amount of nano liquid can improve the comprehensive properties of PU coatings.%介绍了纳米氧化锌浆和纳米改性聚氨酯涂料的制备。通过扫描电镜（SEM）、交流阻抗（EIS）技术、光泽度仪和表面接触角测量仪等分析研究海洋大气和飞溅区环境中纳米改性聚氨酯涂料的耐腐蚀性和抗老化性,探讨了纳米氧化锌浆对聚氨酯涂料性能的改进作用。试验结果表明适量纳米浆提高了聚氨酯涂料的综合使用性能。
