NOVELTY - Preparing pigment printing adhesive comprises (1) dissolving 0.15-0.3 pts. wt. of ammonium persulfate in 25-40 pts. wt. of deionized water in a reactor at 75-80 degrees C and then adding emulsion initiator solution A and B dropwise, reacting for 2 hours, cooling the mixture solution to room temperature and then adjusting pH value to 4-6.5 to obtain polyacrylate emulsion, and (2) dissolving graphite oxide into deionized water and then adjusting the pH value to obtain graphene water solution, adding graphene oxide water solution and 15-18 pts. wt. of polyacrylate emulsion and then stirring. USE - The method is useful for preparing pigment printing adhesive (claimed). ADVANTAGE - The method is capable of preparing pigment printing adhesive with improved dry and wet friction fastness. DETAILED DESCRIPTION - Preparing pigment printing adhesive comprises (1) dissolving 0.15-0.3 pts. wt. of ammonium persulfate in 25-40 pts. wt. of deionized water in a reactor at 75-80 degrees C and then adding emulsion A and B, initiator solution A and B by dropwise, reacting for 2 hours, cooling the mixture solution to room temperature and then adjusting pH value to 4-6.5 to obtain polyacrylate emulsion, where the emulsion A comprises 1-1.6 pts. wt. of sodium dodecyl sulfate, polyoxyethylene ether of branched alcohol, 0.4-1 pts. wt. of deionized water, 20-35 pts. wt. of methacrylic acid, 0.7-1 pts. wt. of diglycidyl ether, 13-16 pts. wt. of methyl methacrylate and 24-30 pts. wt. of butyl acrylate, the initiator solution A is obtained by dissolving 0.3-0.45 pts. wt. of ammonium persulfate in 20-35 pts. wt. of deionized water, the emulsion B comprises 0.5-1.1 pts. wt. of sodium dodecyl sulfate, polyoxyethylene ether of branched alcohol, 1.4-2 pts. wt. of deionized water, 30-45 pts. wt. of methacrylic acid, 2-3.5 pts. wt. of glycidyl ether, 30-45 pts. wt. of methyl methacrylate, 45-60 pts. wt. of butyl acrylate and 6-7.5 pts. wt. of acrylic acid, the initiator solution B is obtained by dissolving 0.55-0.7 pts. wt. of ammonium persulfate in 25-40 pts. wt. of deionized water and (2) ultrasonically dissolving 0.1 pts. wt. of graphite oxide into 100 pts. wt. of deionized water and then adjusting the pH value to 11-12.5 to obtain graphene water solution, adding 1-2.5 pts. wt. of graphene oxide water solution and 15-18 pts. wt. of polyacrylate emulsion and then stirring.
