摘要采用球状锌粉、片状锌粉和片状铝粉为填料,无机树脂为基料,与气相缓蚀(VCI)技术相结合,研制出VCI球片结合型无机锌铝双金属涂料。使用浸涂或喷涂的方式在铁塔用钢板和角钢两类构件上涂覆VCI双金属涂层。利用扫描电子显微镜(SEM)、测厚仪、落锤与划格试验、盐雾试验和紫外老化试验对涂层的微观结构和性能进行表征及测试,并与热浸镀锌试样对比。结果表明:研制涂层附着力、耐蚀性等主要指标优于或达到铁塔用热浸镀锌层要求,这主要归功于VCI和球片结构的相结合。

Abstract: In this paper, spherical zinc powder, flake zinc powder and flake aluminum powder were used as fillers, inorganic resin was used as base material, combined with vapor phase corrosion inhibition (VCI) technology, a VCI spherical-flake combined inorganic zinc aluminum bimetallic coating was developed. Dip coating or spray coating was used to apply VCI bimetallic coating on steel sheet and angle steel components of towers. Use scanning electron microscope (SEM), thickness gauge, drop weight test, cross-cut test, salt spray test and ultraviolet aging test to characterize and test the microstructure and performance of the coating, furthermore, it was compared with the hot-dip galvanized sample. The results show that the main indicators of the developed coating such as adhesion and corrosion resistance are better than or equivalent to the hot-dip galvanized coating of iron towers, this is mainly attributed to the combination of VCI and the spherical-flake structure.

Key words: transmission tower coating flaky zinc powder vapors corrosion inhibiting corrosion resistance
