▎ 摘　　要

NOVELTY - Graphene-modified glue comprises water-based polyurethane adhesive with 30-50% solid content, graphene, and dispersant. Amount of graphene is 0.1-0.25% by mass of adhesive, and amount of dispersant is 1-2.5% by mass of adhesive. USE - Graphene-modified glue used for preparing non-woven fabric (claimed). ADVANTAGE - The glue has improved adhesive performance and heat conductivity. The preparation is simple and reliable. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of graphene-modified glue comprising dispersing graphene powder into deionized water, adding dispersant, stirring at 1000 revolutions/minute for 1 hour; stirring water-based polyurethane adhesive slowly at not greater than 60 revolutions/minute; adding aqueous dispersion of graphene into stirred water-based polyurethane adhesive, and stirring continuously for not less than 30 minutes after adding; ultrasonicating mixture for greater than or equal to 60 minutes at not less than 3 KW power; and standing ultrasonicated mixture for 48 hours, removing settled sediments, and collecting upper layer of uniform emulsion.
