Problems solved by technology

The thermal conductivity of graphene is 5300W / (m·K), and graphene is extracted and separated from graphite, so the graphene conductive film prepared from graphene inherits the advantages of graphene, and is compatible with metallized film Compared, not only has better thermal conductivity, and graphene conductive film does not have insulation defect; ) The "kilometer-level continuous rolled graphene film" exhibited at the International New Material Technology and Industry Expo. The graphene film has excellent electrical conductivity, and its production cost is about 50 yuan / square meter, which is higher than the metallized film. There are many, and the graphene conductive film has a dense structure, and it is very difficult to combine with the polypropylene film

Abstract

The invention relates to a high-temperature polypropylene metalized film. The high-temperature polypropylene metalized film comprises a polypropylene film and a conductive layer, wherein blank edges are arranged on the left and right sides of the conductive layer respectively; the conductive layer comprises multiple graphene conductive films; metal regions are arranged between adjacent graphene conductive films; each metal region comprises two transverse metal straps and multiple longitudinal metal straps; the longitudinal metal straps are arranged between the corresponding two transverse metal straps; the transverse metal straps are electrically connected with the graphene conductive films; blank isolation straps are arranged between the adjacent longitudinal metal straps; and the longitudinal metal straps are electrically connected with the transverse metal straps. The high-temperature polypropylene metalized film is simple in manufacturing process, high in thermal conductivity, resistant to high temperature, less in insulating defects, low in capacitance change after a self-healing test is performed, and long in service life; and meanwhile, the high-temperature polypropylene metalized film can still work normally at a temperature of 120 DEG C without being subjected to breakdown easily.
