The corrosion of metals has caused huge waste and loss to the economic development of society. Zinc - rich coatings have been widely used in the field of anti - corrosion due to their features of simplicity, economy and effectiveness. This paper summarizes the anti - corrosion principles of inorganic silicate zinc - rich anticorrosive coating and relevant research progress at home and abroad. Moreover, the factors influencing the effect of inorganic silicate zinc - rich anticorrosive coating are analyzed and summarized. Finally, the main problems of the coating and the future direction of development are pointed out.
