HEAT-DISSIPATING FILM, AND ITS PRODUCTION METHOD AND APPARATUS |
摘要 |
A heat-dissipating film comprising a heat-conductive layer obtained by burning a mixture layer of flaky carbon and a binder resin to carbonize or burn off the binder resin, and plastic films covering the heat-conductive layer, the heat-conductive layer having a density of 1.9 g/cm3 or more and thermal conductivity of 450 W/mk or more, is produced by (1) sandwiching a mixture layer of flaky carbon and a binder resin with a pair of first plastic films to form a laminated film; (2) heat-pressing the laminated film to densify the mixture layer; (3) burning the mixture layer to carbonize the binder resin in the mixture layer; (4) pressing the resultant burnt layer to form the heat-conductive layer; and (5) sealing the heat-conductive layer with second plastic films. |

1. A heat-dissipating film comprising a heat-conductive layer obtained by burning a mixture layer of flaky carbon and a binder resin to carbonize or burn off said binder resin, and plastic films covering said heat-conductive layer; said flaky carbon in said heat-conductive layer being aligned substantially in parallel; and said heat-conductive layer having a density of 1.9 g/cm3 or more and thermal conductivity of 450 W/mk or more. |
