The invention relates to a hydrophilic acrylate coating printing adhesive for a cotton towel fabric and a preparation method thereof. The hydrophilic acrylate coating printing adhesive is an emulsion prepared from 8-10 parts of alkyl polyether silicone oil, 1.5-2.5 parts of iso-tridecanol polyoxyethylene ether (40), 3-3.5 parts of octadecyl polyethylene glycol methacrylate, 6.8-7.2 parts of organosilicone midbody, 115-125 parts of ethyl acrylate, 5-15 parts of acrylonitrile, 5-15 parts of methyl methacrylate, 1-2 parts of methacrylic acid, 10-12.5 parts of crylic acid, 0.8-1.2 parts of potassium peroxodisulfate, 0.3-0.5 part of sodium acetate and 480-560 parts of deionized water according to an emulsion polymerization method. The towel fabric printing has excellent local hydrophilicity, feels soft and has high firmness.
