NOVELTY - The utility model relates to the technical field of mica paper, and claims a high strength sizing mica paper, comprising a supporting base, the middle part of the supporting base is rotatably connected with a winding shaft, the outer surface of the winding shaft is sleeved with a mica paper main body, the left and right sides of the inner wall of the supporting base are provided with a guide groove. The utility model through the metal wire in the heat-conducting metal net layer is inserted in the mica base layer, capable of efficiently and quickly conducting heat and radiating the heat through the graphene layer, so as to improve the high heat-conducting performance of the mica paper main body, and it is matched with the mica base layer; so as to improve the anti-tensile property of the mica paper main body, the mica paper main body on the winding shaft is fully wound, so that the supporting frame pushes out the blade under the action of the extrusion force, and cutting the mica paper main body, so as to realize automatic cutting, it has simple structure, reduces the investment cost of the device and the cost of later maintenance.
