摘要
铝颜料是一种重要的金属效应颜料,在涂料、油墨、塑料等行业有着广泛的应用;为了增强其耐候性、耐酸碱性以及与树脂间的相容性,在应用前必须对铝颜料进行表面防腐处理。综述了近年来铝颜料表面防腐处理方法,主要有吸附腐蚀抑制剂法和包覆膜法。归纳了腐蚀抑制剂法使用的试剂种类,并分析了防腐试剂的作用原理;介绍了无机钝化、高聚物吸附包覆和表面聚合包覆等3种包覆膜法的机理与工艺。最后展望了该领域的研究方向。
As an important metallic pigment, aluminum pigments are used widely in coating, inks and plastic industry. However, it is necessary to treat the aluminum pigments first to improve the properties of weather-resistance, anti-corrosion in acidic or basic media and compatibility with resin. The methods of surface treatment of aluminum pigments including encapsulation and using corrosive inhibitors are summarized. The kinds of corrosive inhibitors used in the method of corrosion inhibition and their mechanisms are also reviewed. The processes and technologies of inorganic passivation, encapsulation by polymer absorption and by in situ polymerization are introduced. The research directions of aluminum pigments are also presented.
