| 摘要: |
| [目的]探究分子筛作为填料添加到水性涂料中对涂层防腐性能的影响。[方法]利用光学显微镜、XRD及SEM对涂层的中分子筛填料分散效果和涂层微观形貌进行表征，利用极化曲线分析分子筛水性涂层的电化学性能。[结果]分子筛粉末在水性漆中的最大添加比例为15%，超过此比例会出现大块团聚现象。其中10%的分子筛粉末对涂料耐蚀性提升最大。[结论]分子筛良好的高温水热稳定性有助于提高涂料的耐蚀性，但由于水性树脂不能够将分子筛颗粒紧密粘结，其添加量过大时会导致涂层耐蚀性能下降。 |

| Abstract: |
| [Objective] In order to explore the effect of zeolite as filler on the corrosion resistance performance of waterborne coatings.[Methods] The dispersion effect of zeolite filler and micromorphology of coatings were characterized by optical microscopy, XRD and SEM. The electrochemical properties of waterborne coatings were analyzed by polarization curves.[Results] It was found that the maximum addition ratio of zeolite powder to waterborne coatings was 15%.The bulk agglomeration phenomenon appeared beyond this proportion. Among them, 10% of the zeolite powder had the greatest improvement in the corrosion resistance of coatings.[Conclusion] The good high temperature hydrothermal stability of the zeolite helps to improve the corrosion resistance of the coating. However, if the addition amount is too large, the waterborne resin cannot bind the zeolite particles tightly, resulting in a decrease in the corrosion resistance of the coating. |
