Abstract


In this essay, diethanolamine was used to modify the mixed solution of epoxy resin and toughener, and acrylic acid was added in order to generate salt and make the mixture water-soluble. Then the mixed epoxy resin emulsion was prepared with the addition of zinc powder, curing agent and a variety of additives, which was the aqueous organic zinc-rich primer with excellent anti-corrosion properties. In addition, any organic solvent was not used throughout the process.Water-soluble organic zinc-rich primer is almost free of volatile organic compounds.; the corrosion resistance of coating is very well and the paint could immerse in salt water or salt spray more than2000h; this coating has good toughness because of the addition of toughener which could overcome the disadvantage of poor toughness after curing the bisphenol A type epoxy resin. Low amount of zinc powder. There is an excellent anticorrosion effect when zinc powder is only60%of the total mass.
