PURPOSE: An adhesive having high adhesive strength, thermal resistance and water resistance is provided which is used by adding urethane in aqueous acryl emulsion urethane adhesives prior to applying. CONSTITUTION: The aqueous acryl emulsion urethane adhesive is obtained from a method characterized in that urethane curing agent consisting of 20-30 wt.pts. of diisocyanate, 35-45 wt.pts. of polyol, 5-10 wt.pts. of catalyst and additives, and 25-40 wt.pts. of solution is added to aqueous acryl emulsion adhesive consisting of 40-70 wt.pts. of acryl emulsion of 60%, 10-25 wt.pts. of adhesive paste of 50%, 30-45 wt.pts. of stone powder such as calcium carbonate, silica and talc, and 3-10 wt.pts. of additives such as dispersing agent, viscosity improving agent, plasticizer and stabilizer.
