| Abstract: | The organic silicon-epoxy anti-corrosive coating was prepared by organic silicon performed polymer with hydroxyl and bisphenol A type epoxy resin.The nanosilica was adopted to modify organic silicon-epoxy.The effect of amount of organic silicon and nanosilica to performance of coating was investigated by SEM,hardness,impact strength,adhesion,flexibility and electrochemical anticorrosion.It was found that when the ratio of epoxy resin and organic silicon was 2∶1,the organic silicon-epoxy anti-corrosive coating has good adhesion,resistance to aging and anticorrosive.The organic silicon-epoxy anti-corrosive coating modified by nanosilica was synthesized by adding nanosilica solution to organic silicon modified epoxy coating.Compared to organic silicon modified epoxy coating,the organic silicon-epoxy anti-corrosive coating modified by nanosilica has good uvioresistant and resistance to aging. |
