The present invention relates to a heat radiating sheet for an effective radiation by efficiently dissipating and spreading heat generated from the inside of an electrical device and, more specifically, to a method for manufacturing a high content thin graphite heat radiating sheet, capable of manufacturing a heat radiating sheet with excellent thermal properties by having much higher graphite contents compared with an existing graphite heat radiating sheet and reducing the thickness of a sheet significantly, at the same time by using graphite powder as major thermal conductive materials. According to the present invention, the method for manufacturing a high content thin graphite heat radiating sheet comprises the steps of: (a) manufacturing graphite slurry by mixing graphite powder with binders and solvents; (b) forming a graphite layer by spraying the graphite slurry on the base material; (c) drying the graphite layer by evaporating the solvents from the graphite layer; (d) removing a part or all of the binders contained in the graphite layer by burning the binders; and (e) compressing the graphite layer from which the binders are removed by applying pressure. |
