Abstract

The invention discloses a preparation method and a production line of a graphene heat conduction film, and relates to the field of heat conduction device preparation. The preparation method of the graphene heat conduction film comprises the following steps: S1, uniformly stirring and mixing a carbon source and a heat conduction enhancer; S2, carrying out electrical discharge machining on the mixedcarbon source and heat conduction enhancer to obtain doped graphene sheets; S3, screening the doped graphene sheets to obtain graphene coarse sheets; S4, cleaning and drying the graphene coarse sheets; S5, blending the cleaned and dried graphene coarse sheets with an N-methyl pyrrolidone solution to obtain carbon thick slurry; S6, carrying out blade coating on the carbon thick slurry to form a graphene film; and S7, carrying out discharge hot-pressing treatment on the graphene film to obtain the graphene heat conduction film. A wide carbon source is processed to prepare the heat conduction film, so that a solution is provided for solving the heat dissipation problem of next-generation electronic devices, and the industrial requirements of easiness in operation, high efficiency and low cost are met.

Description

technical field [0001] The invention relates to the field of preparation of heat conduction devices, in particular to a preparation method and production line of a graphene heat conduction film. Background technique [0002] With the increasing functionalization and miniaturization of electronic components, a large number of heat generation problems, the accumulation of heat will have a serious impact on the life of electronic equipment, especially with the arrival of the 5G era, the heat dissipation management in communication Performance puts forward higher requirements. Traditional thermal management materials are mainly copper-based, aluminum-based and silver-based metal materials, which have the advantages of good thermal conductivity and easy processing. However, due to the high density value of metal materials, in some applications requiring small weight In some occasions, non-metallic heat-conducting materials are more suitable. In recent years, non-metallic therma...
