The purpose of this utility model is just to provide a kind of heat-conducting double-sided adhesive tape, and it has the feature of better heat conductivility, and the utility model is also very convenient when in use simultaneously.
For achieving the above object, a kind of heat-conducting double-sided adhesive tape of the present utility model comprises adhesive tape basementmembrane, the upper surface of described adhesive tape basementmembrane and lower surface are respectively arranged with the first adhesive-layer and the second adhesive-layer, on described the first adhesive-layer and the second adhesive-layer, be respectively arranged with the first release film and the second release film, the inside of described adhesive tape basementmembrane is distributed with some graphite granules equably, and described the first adhesive-layer and the second adhesive-layer inside are distributed with powdered graphite.
As technique scheme preferably, described the first adhesive-layer and the second adhesive-layer are on the surface that sectional type is distributed in adhesive tape basementmembrane, between every two sections of adhesive-layers, are interval section.
As technique scheme preferably, described the first adhesive-layer and the second adhesive-layer be have high thermal conductivity can acryl glue-line, in this acryl glue-line doped with Graphite Powder 99.
As technique scheme preferably, described the first release film is that integral body is continuous shape, described the second release film is that sectional type distributes, described the second adhesive-layer contacts with electronic original part, described the first adhesive-layer contacts with radiator element.
As technique scheme preferably, described adhesive tape basementmembrane is provided with transversal at interval section place, described the second adhesive-layer and adhesive tape basementmembrane corresponding section are provided with transversal.
