A waterborne acrylic topcoat applied for containers was developed. The waterborne acrylic topcoat was prepared by using acrylic emulsion with different Tg as film forming material，adding pigments and fillers and additives suitable for waterborne coatings.The effects of various proportions of acrylic emulsion，p/b ratio，amount of quick drying solvent，type and amount of thickeners，defoamer and other formulation parameters on the properties of coatings were emphatically investigated. Through orthogonal experiments，a water-borne acrylic topcoat with excellent comprehensive properties was developed，which met the technical requirements in the standard of JH/T E08—2015（Test method and acceptance standard for freight containers）prepared by CCIA.
