Background technique
Currently, market portioned product carries out heat conduction and heat radiation, especially copper and aluminium by metal group material, but the weight of copper
Greatly, oxidizable to limit its application, and the capacity of heat transmission of aluminium is difficult meet the needs of existing product is to heat conduction and heat radiation.And graphite
Alkene is the carbon atomic layer of monoatomic thickness, and thinner thickness, rigid, heat transmitting is good, in terms of have it is good
Good application prospect.Graphene processing film forming is come to electronic product heat radiation performance, and existing graphene heat dissipation film is using
When, it is difficult meet the needs of to electronic product heat conduction and heat radiation, leading to existing graphene heat dissipation film, heat dissipation effect is not when in use
It is good.Moreover, when current graphene film and heat generating components are viscous glutinous, be difficult it is accurately viscous bond to desired position, and it is viscous it is glutinous after
Both ends are Nian Jie with heat generating components too tight, can be very troublesome when film, which goes wrong, to be needed to tear.
Summary of the invention
The purpose of the present invention is to solve the above the deficiencies in the prior art, provide a kind of graphene THIN COMPOSITE of high thermal conductivity
Film is easy to paste and conveniently tears replacement.
The technical scheme adopted by the invention is as follows a kind of graphene composite film of high thermal conductivity, including heat dissipation membrane body, institute
The thermally conductive membrane body stated successively includes release film, adhesive layer, buffer layer, heat dissipating layer and PET film layer from bottom to up；Described is release
Film is divided into the small release film of muti-piece by dotted line shape breakpoint；It is equipped between the release film and adhesive layer and easily tears component, described is easy
The cohesive force for tearing component and adhesive layer is stronger than the cohesive force for easily tearing component and release film；It is described easily to tear component at least one end and prolong
It extends to outside adhesive layer.
Preferably, the heat dissipating layer is made of upper heat conduction silicone and lower heat conduction silicone, the upper heat conductive silica gel
Layer lower surface is identical as lower heat conduction silicone surface structure, and equal spaced array is provided with protrusion and recess portion, Graphene powder filling
Between the upper and lower heat conduction silicone.For the heat transfer of heat generating components to heat dissipating layer, heat dissipating layer has concaveconvex structure, recessed
It is covered with graphene in male structure, increases the contact area of graphene, accelerates heat conduction and heat radiation.
