▎ 摘  要

NOVELTY - The utility model claims a mica tape with reinforced wrapping, comprising a mica paper and baseband wrapping mica paper layer; one side surface of the mica paper baseband formed with a graphene film layer with hole, the outer surface of the graphene film with hole is formed with a first adhesive layer, and the surface of the adhesive layer is formed with polyimide film layer; the other side surface of the mica paper baseband formed with a second adhesive layer, and the surface of the second adhesive layer is formed with a reinforcing fibre fabric layer; the wrapping mica paper layer has a width greater than that of the mica paper baseband and a third adhesive layer is formed on one side, the wrapping mica paper layer is attached to the side of the polyimide film layer of the mica paper baseband and the mica paper baseband wrapped by the reinforcing fibre fabric layer side. The mica tape of the utility model can ensure the electrical performance of the mica paper tape and ensure the tensile strength, and it can effectively wrap the edge of the edge of the lapping process of the mica tape because of the edge cracking of the strength defect.
