▎ 摘  要

NOVELTY - The utility model claims a radiating shielding copper foil with high radiating performance, comprising a rolled copper foil main body, the surface of the rolled copper foil main body is provided with a radiating layer, the surface of the radiating layer is provided with a shielding layer, the radiating layer comprises graphene radiating coating, high heat conducting silicone grease and aluminium oxide coating, the top part of the coating is aluminium oxide with a high heat conducting silicone grease, the top part of the high heat conducting silicone grease is provided with a radiation radiating coating, the top part of the radiation radiating coating is provided with a graphene, the shielding layer comprises a conductive rubber, a wave absorbing material and a conductive complexing agent. The utility model through setting the rolled copper foil main body can be used as conductive material, by setting the radiating layer to increase the radiating coefficient of the rolled copper foil main body, at the same time, it solves the problem that the currently used rolled copper foil radiating and shielding effect is bad, which not only reduces the practicability of the rolled copper foil, but also increases the trouble of the using staff.
