Graphite aluminum foil heat-conducting material

Abstract

The invention discloses a graphite aluminum foil heat-conducting material which is successively composed of a black matt base material layer, a graphite base material layer, an aluminum foil base material layer, and a PET release film. One surface of the black matt base material layer is bonded with one surface of the graphite base material layer by using an adhesive material layer. The other surface of the graphite base material layer is bonded with one surface of the aluminum foil base material layer by using an adhesive material layer. The other surface of the aluminum foil base material layer is bonded with one surface of the PET release film by using an insulating adhesive layer. The black matt base material layer, the graphite base material layer, the aluminum foil base material layer, and the PET release film are successively and mutually bonded together to form the graphite aluminum foil composite diaphragm material. According to characteristics of the black matt base material layer, the graphite base material layer, the aluminum foil base material layer, and the PET release film and effects obtained in a plurality of experiments, the graphite aluminum foil heat-conducting material has the advantages of light weight, a good heat-dissipating effect, and excellent performance such as high and low temperature resistance, corrosion resistance, non-ageing performance, self-lubricating performance, compressibility, rebound resilience and sealing performance.

Description

technical field [0001] The invention relates to the field of thermally conductive materials, in particular to a graphite aluminum foil thermally conductive material. Background technique [0002] In recent years, with the gradual popularization of electronic products and the acceleration of upgrading, and the increasing of highly integrated and high-performance electronic equipment, the size of working components is getting smaller and smaller, the speed and efficiency of work are getting higher and higher, and the heat generation is also decreasing. getting bigger. At present, the known metal heat conduction and heat dissipation components have been limited by their materials and their own heat conduction and heat dissipation limits. Advanced heat conduction and heat dissipation technology and excellent heat conduction and heat dissipation materials must be used to effectively remove heat to ensure the effective work of electronic products. , graphite heat dissipation mate...
