▎ 摘　　要

NOVELTY - Thermally conductive copper foil, comprises a superconducting copper layer, a thermally and electrically conductive layer, and a release film layer, where the superconducting copper layer is composed of copper, graphene and carbon nanotubes, the thermally and electrically conductive layer is composed of epoxy resin, graphite, alumina powder, conductive silicone grease, catalyst, thixotropic agent and surfactant, and the release film layer is transparent release film. USE - Used as thermally conductive copper foil. ADVANTAGE - The thermally conductive copper foil: has excellent electrical conductivity and corrosion resistance; improves the thermal conductivity and corrosion resistance of the product; avoids additional coating of a corrosion-resistant layer on the outside of the product; and solves the problem of poor corrosion resistance of the existing thermally conductive copper foil and thus resulting in a long service life. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing thermal conductive copper coil, comprising (i) heating the copper at 1120-1140degrees Celsius to melt it into a liquid state, then removing the alloy impurities in the copper liquid, and purifying the copper liquid, (ii) adding graphene and carbon nanotubes into the copper liquid prepared in step (i), stirring and heating, and cooling to obtain superconducting copper, (iii) placing epoxy resin, graphite, alumina powder and conductive silicone grease into a reaction kettle, stirring and heating at 3660-3750degrees Celsius to make it molten, (iv) adding catalyst, thixotropic agent and surface treatment agent respectively into the reaction kettle, stirring for 1-2 hours, and finally cooling to room temperature to obtain liquid-type thermally and electrically conductive material, (v) extruding the superconducting copper prepared in step (ii) into thin sheets, then spraying the liquid-type thermally and electrically conductive material prepared in step (iv) on the surface of the superconducting copper, and baking to obtain thermally and electrically conductive layer, and finally covering the transparent release film on the outside of the thermally and electrically conductive layer to obtain finished product, and (vi) inspecting the finished product, and packaging and placing into storage after passing the inspection.
