NOVELTY - The preparation method of graphene high oil absorbent resin involves: (1) adding modified porous graphene or modified porous graphene antibacterial composition to deionized water so that the concentration of modified porous graphene or modified porous graphene antibacterial composition is 0.5-10 mg/ml, and carrying out ultrasonic dispersion to obtain a modified porous graphene suspension; and (2) adding a certain amount of deionized water to a reaction container, adding emulsifying agent, stirring to fully dissolve emulsifying agent, and then adding acrylate monomer. USE - The method is useful for preparing graphene high oil absorbent resin. DETAILED DESCRIPTION - The preparation method of graphene high oil absorbent resin involves: (1) adding modified porous graphene or modified porous graphene antibacterial composition to deionized water so that the concentration of modified porous graphene or modified porous graphene antibacterial composition is 0.5-10 mg/ml, and carrying out ultrasonic dispersion for 1-24 hours to obtain a modified porous graphene suspension; (2) adding a certain amount of deionized water to a reaction container, adding emulsifying agent, stirring at a speed of 300-500 rpm to fully dissolve emulsifying agent, and then adding acrylate monomer to obtain a stable emulsion; (3) adding modified porous graphene suspension obtained in step (1) to emulsion obtained in step (2), continuously stirring and emulsifying for 30-60 minutes, then adding chemical crosslinking agent and pore-forming agent and continuously stirring for 10-30 minutes; (4) heating at 40-70 degrees C, dripping solution prepared from initiator into emulsion, continuously stirring until the solution is stable, and reacting for 2-20 hours to obtain porous high oil absorbent resin gel with connected pore structure; and (5) granulating the resin gel after the step (4) is completed, drying to constant weight in a drying oven at 105-180 degrees Cto obtain product.
