▎ 摘　　要

NOVELTY - A graphene-modified acrylic resin comprises 55-70 pts. wt. solid acrylic resin, 1-5 pts. wt. graphene, 2-6 pts. wt. dispersing agent, 2-6 pts. wt. transfer agent, 3-8 pts. wt. pH regulator and 20-26 pts. wt. deionized water. USE - Graphene-modified acrylic resin for aqueous ink. ADVANTAGE - The acrylic resin is non-toxic, non-polluting, non-combustible, non-explosive, safe and environmentally-friendly, has high solid content, low viscosity, excellent water solubility, film-forming property, pigment dispersion property and color paste stability, and is prepared by a simple method. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of graphene-modified acrylic resin which involves mixing solid acrylic resin, dispersing agent and deionized water at 65-75 degrees C and at 600-800 rpm for 3-5 hours to obtain a homogeneous mixture, adding graphene and transfer agent to the mixture and stirring for 5-7 hours under the same conditions, and distilling off deionized water at 0.1-0.2 atm.
