Abstract
The invention discloses a method for manufacturing a thermally and electrically conductive graphite ribbon, which comprises the following steps of: 1) sprinkling graphite powder onto an adhesive film with a basement film by using a powder gun; and 2) rolling and leveling the graphite powder and the adhesive film to obtain the thermally and electrically conductive graphite ribbon. In the method for manufacturing the thermally and electrically conductive graphite ribbon, the graphite powder is sprinkled onto the adhesive film, and a rolling and leveling method is adopted so as to overcome the shortcoming that a flexible graphite sheet is easy to break; in the manufacturing process, the processes of heating, baking and the like are not required so as to achieve low energy consumption; the obtained finished product can be used for the thermal conduction of curved surfaces such as surfaces of pipelines with the coefficient of thermal conductivity of 400W/mK which is higher than that of an aluminum foil; and the graphite material is difficult to oxidize, so the finished product obtained by the method is more durable, and is applied in the fields of thermal conduction of the surfaces and heating films.
