▎ 摘 要
NOVELTY - The utility model belongs to the technical field of protective film and claims a substrate-free graphite heat-conducting film, used for solving the problem existed in present there is substrate alkene product. The utility model comprises an acrylic adhesive layer coated on the upper surface of the graphene layer, the graphene layer, and the upper surface of the acrylic adhesive layer is attached with light separated type film; the lower surface of said graphene layer is set with insulating OPP film. The utility model without substrate graphite heat conducting film with high heat conductivity, heat conduction coefficient can reach 1700-1900W/m-K; and has surface insulating characteristics, even if the curved object can reach the good heat conduction effect, and has low cost and is convenient to manufacture.
