基于锌防护层修复及钢结构防护的背景，针对一种锌防护层修复涂料，研究其组分(复合锌粉、有机?无机杂化改性剂)对涂层防护性能的影响，并与同类进口产品对比分析。结果表明：在颜基比(质量比)4：1时，随复合锌粉含量的增加，涂层的附着力增大；有机?无机杂化改性剂可有效提高涂层的附着力与耐蚀性；多形态复合锌粉涂层的耐蚀性优于球状复合锌粉涂层的。在热浸锌、电镀锌、Q235(St3)基材上，锌防护层修复涂层耐紫外大于2000 h，耐盐雾大于3000 h；且在Q235(St2)基材上耐盐雾大于2000 h，其防护性能远高于同类进口产品的。

Based on the background of protective zinc layer repair and steel protection, one protective zinc layer repairing paint was studied. The influence of the components (compound zinc powder and organic-inorganic hybrid modifier) on coating performance was analyzed and compared. The results indicate that the coating adhesion increases with increasing the content of compound zinc powder at the pigment/binder mass ratio of 4:1, and the organic-inorganic hybrid modifier enhances the coating adhesion and corrosion resistance. Moreover, the coating with compound zinc powder of multiple forms has superior corrosion resistance than that of different spherical diameters. The resistance of UV accelerated aging and neutral salt spray on hot-dip zinc, galvanized steel sheet and Q235(St3) are more than 2000 h and 3000 h, respectively. The neutral salt spray resistance on Q235(St2) is longer than 2000 h, providing that it has higher protective ability than imported products.
