摘要（英）：

The invention provides a bisphenol-A-free water-based internal repair coating for an inner edge seam of a three-piece can. The bisphenol-A-free water-based internal repair coating comprises the following components in percentage by weight: 60-70% of polyolefin water-based dispersion; 0-10% of a waterborne polyester resin dispersion; 0-10% of a waterborne acrylic resin dispersion; 24-34% of deionized water; 0.1-0.2% of dimethylethanolamine; 0.2-1.2% of hydroxyalkyl amide; 0-4% of phenolic resin; 0-4% of amino resin; 3-5% of an ether solvent; and 0-1% of an alcohol solvent. The invention furtherprovides a preparation method and a spraying method of the bisphenol-A-free water-based internal repair coating for the inner edge seam of the three-piece can. The invention aims to provide a solution for repairing the water-based inner edge seam of the three-piece beverage can and meet the requirement of novel bisphenol-A-free food sanitation.
