▎ 摘  要

NOVELTY - The method involves plasticizing the graphene sheet. The keen graphene sheet is ordered. The graphene sheet plasticized is roll pressed. The roll press satisfies the predetermined condition relating temperature of plasticity, temperature of the plate press, temperature of roll press, pressure of plasticity, pressure of the Plate presses and pressure of the roll press. The graphene sheet I provided with the graphene plate of twelve sheets. The polymer resin and solvent are mixed manufacturing the graphene resin. The release film is coated and the graphene resin is dried to manufacture the graphene sheet. The multiple graphene plates are made with laminated paper, where polymer resin is the rubber system resin, urethane resin, and acrylic resin, and at one kind selected from the group consisting of the polyvinyl resin. USE - Manufacturing method of heat radiation graphene sheet. ADVANTAGE - The heat-radiating graphene sheet is thin, and has excellent durability, enhanced thermal conductivity, and excellent heat-radiation properties. DETAILED DESCRIPTION - The solvent is provided with polymer resin from the group consists of 80-150pts. wts. of toluene and ethyl acetate. The coating is coated one side of the release film with the graphene resin in the speed of 6-12 m divide by min. The laminated paper is performed in a line pressure 3-12 kgf and temperature 60-140 degrees C. The plasticity is performed under the pressurization condition of the pressure 1.5-38kpa and temperature 450-750 degrees C for 1-3hours. An INDEPENDENT CLAIM is included for a heat radiation graphene sheet has thickness of 15-35 mu m and thermal conductivity of 550-720 W divide by m.K.
