A silicone modified acrylic emulsion has been prepared by using a semi-continuous emulsion polymerization method, with acrylate monomers and other functionalmonomers of epoxy acrylate and vinyl siloxane, which was added as an organic film-formingmaterial into the inorganic potassium silicate solution, which was then mixed with zinc powderto prepare a waterborne inorganic zinc-rich coatings with excellent adhesion and flexibility.The morphology and structure of the synthesized silicone modified acrylic emulsion werecharacterized by infrared spectroscopy（FT-IR）and transmission electron microscopy（TEM）. The surface morphology of the modified hybrid coatings film and its zinc-rich coating wasanalyzed by scanning electron microscopy（SEM）. The corrosion resistance of zinc-rich coatings was tested using electrochemical impedance spectroscopy（EIS）. The results showed that the zinc-rich coatings modified by the homemaesilicone modified acrylic emulsionprovided the adhesion of rate 0 and flexibility of 1 mm, and the corrosion resistance is obviouslyimproved.
