PURPOSE: An acryl-based emulsion-type adhesive polymer and an aqueous adhesive for a tile prepared from the polymer are provided, to improve the state adhesive strength and the smear fastness adhesive strength. CONSTITUTION: The acryl-based emulsion-type adhesive polymer is prepared by the emulsion polymerization of monomers having a double bond, wherein the monomers having a double bond comprises 20-60 wt% of a cohesive monomer, 20-80 wt% of an adhesive monomer and 0.1-20 wt% of an ethylene-based unsaturated carbonic acid monomer. Preferably the cohesive monomer is at least one selected from the group consisting of methyl methacrylate, acrylonitrile, ethyl methacrylate and vinyl acetate; the adhesive monomer is at least one selected from the group consisting of 2-ethylhexyl acrylate and butyl acrylate; and the ethylene-based unsaturated carbonic acid is at least one selected from the group consisting of acrylic acid, methacrylic acid, crotonic acid, maleic acid, fumaric acid and itaconic acid. The glass transition temperature of the acryl-based emulsion is -25 to 15 deg.C.
