| Abstract: | The styrene-acrylic emulsion was modified by a new bis-alkoxyl silane coupling agent and a conventional trialkoxyl silane coupling agent. The corrosion protection property of the coating before and after modification was studied by electrochemical impedance spectroscopy (EIS). The results showed that the corrosion protection property of the modified coating is better than that of the unmodified coating, and the corrosion protection performance of the styrene acrylic emulsion modified by the new bisalkoxyl silane coupling agent KH-578 is the best. |
