The invention discloses a manufacturing method of a heat conduction and heat radiation electromagnetic shielding film. The manufacturing method of the heat conduction and heat radiation electromagnetic shielding film is characterized in that the method comprises the steps A1) forming an erosion effect on the surface of a metal film through corona processing; A2) coating adhesive on the surface at one side of the metal film; A3) placing the metal film coated with the adhesive into a drying oven for drying; A4) coating graphite pulp on the surface at one side, having the adhesive coating layer, of the metal layer; A5) placing the metal film coated with the graphite pulp into the drying oven for drying again; and A6) squeezing the metal film to a target size through upper and lower two squeezing rubber rollers, and then, rolling up the prepared heat conduction and heat radiation electromagnetic shielding film. The manufacturing method of the heat conduction and heat radiation electromagnetic shielding film is simple in process and easy to produce, can realize automatic operation more conveniently, reduce production cost effectively and reduce dependence on labors.
Description
technical field [0001] The invention relates to an electromagnetic shielding film, in particular to a manufacturing method of the electromagnetic shielding film for heat conduction and heat dissipation. Background technique [0002] The electromagnetic shielding film is mainly a film made of materials with conductive properties, which is attached to the peripheral side of the electromagnetic device to suppress electromagnetic interference. [0003] Since the electromagnetic shielding film is arranged on the peripheral side of the electromagnetic device, the heat generated during the operation of the electromagnetic device cannot be discharged in time, resulting in local overheating of the electromagnetic device and affecting the normal operation of the device. [0004] Therefore, there is a need for a heat-conducting and heat-dissipating electromagnetic shielding film that can realize electromagnetic shielding and can also quickly discharge heat, so as to ensure the normal o...
