摘要
以环氧树脂为成膜物质,加入颜填料、纳米二氧化硅和聚硅氧烷偶联剂,制备了电力金属防腐蚀的纳米复合底漆。以现用底漆做对比,采用模拟酸雨实验、浸泡实验和电化学阻抗谱实验考察了两种涂层的耐腐蚀性能。结果表明,纳米复合底漆的耐腐蚀性能优于现用底漆,更加适合用作电力金属设施的防护涂层。
A nanocomposite coating was prepared with epoxy resin as film-forming agent,polysiloxane as coupling agent and with proper additives of pigments, fillers and nano silicon dioxide.The nanocomposite coating was applied on carbon steel Q235, and its corrosion performance, in comparison with a present used coating, was investigated by means of simulate acid rain test, immersion test and electrochemical impedance spectroscopy. Results showed corrosion resistance of the nanocomposite coating is better than that of the current coating, it is suitable especially for the protection of engineering steel components for electric power facilities.
