摘要

为替代对环境污染严重的传统磷化和六价铬钝化技术，制备了一种由氨基硅树脂、聚氨酯树脂和无机金属组成的硅烷钝化液，将该钝化液涂布于脱脂后的铝板表面使其形成有机无机杂化膜。研究了钝化液pH 值、氨基硅树脂的质量分数、聚氨酯树脂的质量分数和无机金属离子Zn2＋、Mn2＋、Ni2＋和Ce3＋的种类对杂化膜耐腐蚀性能的影响，并用IR、SEM 和TGA 对杂化膜进行形貌和结构的表征，通过电化学实验测出不同条件下涂覆杂化膜的铝板的开路电位、EIS 谱和Tafel 极化曲线对杂化膜进行耐腐蚀性能表征。结果表明:pH 值趋于4.5、氨基硅树脂质量分数占15.0%、聚氨酯树脂质量分数占10.0%、金属离子为1.5%Zn2＋时所得杂化膜耐腐蚀性能较好。

Abstract

To replace traditional phosphating and hexavalent chromium passivation technologies， which cause serious environmental pollution，a silane passivation solution was prepared.This solution was composed of amino silicone resin， polyurethane resin and inorganic metal.It was then coated on the degreased aluminum plate surface to form an organic-inorganic hybrid film.The study investigated the effects of various factors on the corrosion resistance of the hybrid membrane: the pH value of the passivation solution， the mass fractions of amino silicone resin and polyurethane resin and the types of inorganic metal ions (Zn2＋， Mn2＋， Ni3＋and Ce3＋).The morphology and structure of the hybrid membrane were characterized by infrared spectrum (IR)， scanning electron microscopy (SEM) and thermogravimetric analysis (TGA).Characterizing the corrosion resistance of hybrid membrane by measuring the open circuit potential， EIS spectrum and Tafel polarization curve of aluminum plates coated with hybrid membrane under different conditions through electrochemical experiments.Results showed that the hybrid membrane exhibited good corrosion resistance when the pH value was around 4.5， the mass fraction of amino silicone resin was 15.0%， the mass fraction of polyurethane resin was 10.0%， and the metal ion was 1.5%Zn2＋.
