摘　　要：为了改善绢云母在环氧树脂涂料中的分散性,增强它与环氧树脂涂料的相溶性,用硅烷偶联剂(KH-550)对绢云母进行表面改性,并将改性后的绢云母用于环氧树脂涂料中.结果表明:通过偶联剂包覆改性后,绢云母在环氧树脂涂料中的分散性得到了提高,它与环氧树脂涂料的相溶性也得到明显提高,并且添加了改性后的绢云母的涂料防腐性能也得到了提高.Surface of sericite was modified using silane coupling agent（KH -550）,and the modified sericite was added into epoxy coating.Infrared spectroscopy（FT-IR） analysis shows that silane coupling agent is successfully coated on the surface of sericite.After modification,the dispersion of sericite in the epoxy coating is greatly improved,and its compatibility with epoxy coating is obviously increased.Electrochemical Impedance（EIS） results indicate that the addition of modified sericite can greatly improve the anti-corrosion property of the coating.
