Abstract: Ahigh performance waterborne zinc coating was prepared by modifying acrylic resin using silane (A-187) and high modulus potassium silicate.The storage stability of the coatings and the surface morphology, composition and corrosion resistance of the coatings were characterized and analyzed by Fourier infrared spectroscopy, SEM, EDS energy spectroscopy, X-ray diffraction (XRD), neutral salt spray and electrochemical tests. The results showed that: A187, potassium silicate and aqueous acrylic resin were successfully cross-linked and modified to form an aqueous resin shell structure on the surface of zinc powder to protect the active zinc powder; SEM showed that the zinc powder was uniformly distributed and the surface of the coating was smooth and flat without obvious defects; after 1 000 hours of neutral salt spray test, the surface of the coating was free of red rust; compared with the solvent-based Zn coating, the coating resistance of the water-based Zn coating prepared in this paper is increased by nearly two orders of magnitude, and the coating has better protective properties.
