摘　　要：铝颜料因其优良的性能而在各相关领域获得广泛应用,但防腐蚀性能不佳又使其应用受到极大限制。活性二氧化硅包覆铝颜料能够得到均匀致密的包覆膜,使铝颜料具有良好的耐腐蚀性能,因而逐渐成为研究的热点。介绍了铝颜料的表面性质和二氧化硅包覆铝颜料的方法,如无机二氧化硅包覆和有机-无机杂化包覆,并综述了不同催化剂条件下二氧化硅包覆铝颜料的研究状况。Due to the excellent performance in all relevant areas, aluminum pigments have obtained a wide range of applications, but are greatly limited by their poor anti- corrosion property. An uniform and compact encapsulated coating can be obtained with reactive silica-coated aluminum pigments with good corrosion resistance, leading to a research hotspot gradually in recent years. An introduction was given of the surface properties of aluminum pigments and the coating methods using SiO2, such as inorganic silica encapsulation and organic-inorganic hybrid encapsulation. The research status of aluminum pigments coated by SiO2 with different catalysts was summarized.
