    • A surface treatment solution for autodeposition coating treatment of a metallic material, which is an aqueous solution comprising at least one tannin, at least one crosslinking agent having a crosslinking group capable of thermosetting reaction with a phenolic hydroxyl group and/or a phenolic nucleus, ferric ions, soluble type elemental fluorine, and an oxidizing agent, wherein the solids mass concentration ratio of the tannin to the crosslinking agent is in the range of from 1:1 to 1:10, the molar concentration of the soluble type elemental fluorine is at least 3-fold the molar concentration of the ferric ions, and the pH of the solution is from 2 to 6. The surface treatment solution allows shorter process length as compared with conventional coating processes, generates less environmentally harmful by-products such as sludge, has excellent throwing power at the interior of a pocket structure, does not use environmentally harmful components such as chromium compounds, has corrosion resistance, and allows overcoating of a baking finish on the obtained coating film.
    • 一种用于自动沉积涂覆处理金属材料的表面处理溶液,其是包含至少一种单宁的水溶液,至少一种具有能够与酚羟基和/或酚核心进行热固化反应的交联基团的交联剂,三价铁 离子,可溶型元素氟和氧化剂,其中单宁与交联剂的固体质量浓度比在1:1至1:10的范围内,可溶型元素氟的摩尔浓度为 三价铁离子的摩尔浓度至少为3倍,溶液的pH为2〜6。表面处理溶液与常规涂布方法相比,加工时间缩短,生成较少的环境有害副产物如污泥, 在口袋结构的内部具有优异的抛光力,不使用环境有害的成分,如铬化合物,具有腐蚀性 并且允许在所获得的涂膜上涂覆烤漆。
