摘　　要：以水性聚酯涂料为底漆,研究了不同烘烤工艺对涂层耐碱性腐蚀的影响。在确定最佳烘烤工艺(210℃、2 min)后,实验加入了多磷酸钼锌水合物(ZPA)、改性正磷酸盐(ZMP)、有机改性磷酸锌铝钼水合物(ZPO)、有机缓蚀剂(RZ)4种纳米粉末,结合电化学测试和碱性腐蚀实验,评估其对涂层耐腐蚀性能的影响。实验结果表明,加入纳米粉末后,涂层的耐腐蚀性能显著提升,尤其是添加0.5%(质量分数,后同)RZ+2.5%ZPO的涂层表现出最佳的电化学耐腐蚀性能。该研究为开发高性能卷尺用聚酯涂层提供了有效的理论依据与实验支持。In this study,waterborne polyester coatings were used as the primer to investigate the impact of different baking processes on the alkali corrosion resistance of the coatings.After determining the optimal baking process(210 ℃,2 minutes),four types of nano-powders(RZ,ZPA,ZMP,and ZPO) were added,and their effects on the coatings' corrosion resistance were evaluated through electrochemical testing and alkaline corrosion experiments.The experimental results showed that the corrosion resistance of the coatings was significantly improved after the addition of nano-powders,with the coatings containing 0.5%(wt.%,the same below) RZ+2.5% ZPO exhibiting the best electrochemical corrosion resistance.This study provides effective theoretical and experimental support for the development of high-performance polyester coatings for measuring tapes.
