The invention relates to the technical field of painting, particularly to a highly-adhesive elastic emulsion paint. The highly-adhesive elastic emulsion paint is composed of pure acrylic emulsion, styrene-acrylic emulsion, inorganic filler, compound thickening agent, polytetrafluoroethylene-polyurethane copolymer, polyacrylamide, nanometer titanium dioxide, preservative, defoamer, leveling agent and deionized water, wherein the compound thickening agent is a special combination prepared by compounding materials such as mucopolysaccharides, modified cellulose and modified starch; the organic filler is a mixture of titanium dioxide, talcum powder and light calcium carbonate; the preservative is 1, 2-benzisothiazolin-3-one, methylisothiazolinone or 5-chloro-2-methyl-4-isothiazolinone-3-one. The highly-adhesive elastic emulsion paint is high in adhesiveness and easy to dry and cure and can form coating high in elasticity, strength and washing resistance.
