Method for coating metal surfaces with an aqueous, polymer-containing composition, said aqueous composition and the use of the coated substrates
摘要：
The invention relates to a method for coating a metal surface with an aqueous composition, characterized in that the composition contains, in addition to water: a) at least one organic film former that contains at least one water-soluble or water-dispersible polymer with an acid number ranging from 5 to 200, b) at least one particulate inorganic compound with an average particle diameter measured by a scanning electron microscope in the range of from 0.005 to 0.3μ, c) at least one slip additive and/or at least one corrosion inhibitor, d) optionally at least one organic solvent, e) optionally at least one silane and/or siloxane, f) optionally at least one cross-linking agent, and g) optionally at least one chromium (VI) compound. The clean metal surface is contacted with the aqueous composition and a particle-containing film is formed on the metal surface which is then dried. The dried and optionally also cured film has a layer thickness ranging from 0.01 to 10 μm. The invention further relates to a corresponding aqueous composition.
摘要（中）：

本发明涉及一种用水性组合物涂覆金属表面的方法，其特征在于该组合物除了水以外还含有：a）至少一种含有至少一种水溶性或水分散性聚合物的有机成膜剂， b）通过扫描电子显微镜测量的至少一种平均粒径为0.005至0.3μm的至少一种颗粒状无机化合物，c）至少一种滑爽添加剂和/或至少 一种腐蚀抑制剂，d）任选的至少一种有机溶剂，e）任选的至少一种硅烷和/或硅氧烷，f）任选的至少一种交联剂，和g）任选的至少一种铬（VI）化合物。 清洁的金属表面与水性组合物接触，并且在金属表面上形成含有颗粒的膜，然后将其干燥。 干燥的和任选的固化的膜具有0.01至10μm的层厚度。 本发明还涉及相应的水性组合物。
