▎ 摘  要

NOVELTY - The method involves etching a polyimide (PI) copper film to form a copper foil electrode circuit. A graphene electro-thermal slurry is printed in a heating area. The thermal slurry is dried to form heat generating graphene. The heat generating graphene is connected with a copper foil electrode circuit. A heat-conducting paste layer is coated on a surface of the PI copper film printed with a heat graphene generating layer. A dry film is formed. Excess capping agent is added to completely end capping reaction. Polyurethane resin preparation process is performed. Boron nitride powder is uniformly mixed with peeling agent. USE - Method for preparing a high heat conducting graphene heating body for use in an electric heating glove (claimed). ADVANTAGE - The method enables utilizing heat conducting slurry with hot melt adhesive property to replace a glue film and a bonding layer, and forming heat transfer graphene of a heat conducting slurry layer-heat conducting slurry layer-glove lining cloth so as to make heat graphene to quickly transmit heat to the glove lining cloth, thus reducing heat loss. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a high heat conducting graphene electric heating glove preparation method. DESCRIPTION OF DRAWING(S) - The drawing shows a sectional view of a high heat conducting graphene electric heating glove.
