▎ 摘 要
NOVELTY - The application model relates to the technical field of radiating material, especially relates to a heat conducting film, the heat conducting film comprises a composite layer, the composite layer comprises at least one graphene layer, no base material heat-conducting double-faced adhesive layer and artificial graphite layer; the non-substrate heat-conducting double-sided adhesive layer is set on at least one side of the artificial graphite layer, the graphene layer is set on one side of the non-substrate heat-conducting double-sided adhesive layer far away from the artificial graphite layer. The heat-conducting film of the application, the non-substrate heat-conducting double-faced adhesive layer is set on the two sides of the artificial graphite layer, the heat-conducting film can be firmly adhered between each layer; it also has a certain supporting effect, it is good for cutting and forming of the heat-conducting film; and there is no base material heat conducting double-sided adhesive layer capable of efficiently transmitting the heat energy to the graphene layer and the artificial graphite layer, the heat is fast and efficient. alternately overlapped layer structure, it also can avoid damage to the graphene layer caused by die cutting, at the same time, it can optimize the die cutting process, improve the die-cutting adaptability of the heat conducting film, and is good for forming the ultra-high thickness heat conducting film, the satisfy requirement of the large size electronic product.
