Background technology
As electronic device and product develop to high computing, highly energy-consuming direction, machine radiating becomes the difficulty for being badly in need of solving,
At present various Heat Conduction Materials are extensively applied, but heat conductivility is determined by material factor itself, its thermal coefficient differences compared with
Greatly, the heat conductivity of part material is as shown in the table：
The material that heat conduction is carried out using the metals such as aluminum bronze and graphite in the market is relatively more, but buys to requiring increasingly
High product needed, carries out heat conduction in the urgent need to the heat conductivity highest Graphene that has now been found that, but due to graphite
Alkene has the characteristic such as powder, frangible, Graphene must be coated on the best Copper Foil of heat conductivity and economy in prior art
On, and this mode have impact on overall heat conductivity.
Therefore prior art has base material graphene product low due to base material heat conductivity, so as to cause whole structure not dashed forward
Go out, or even the heat conductivility not as graphite occur.
Utility model content
This utility model is poor in order to solve the problems, such as the existing heat conductivility with the presence of base material graphene product, and provides one
Plant without base material Graphene heat conducting film.
For solving above-mentioned technical problem, the technical scheme adopted by this utility model is：
One kind is without base material Graphene heat conducting film, it is characterised in that including graphene layer, the upper surface of the graphene layer is applied
Acrylic acid glue-line is furnished with, the upper surface of the acrylic acid glue-line is pasted with light mould release membrance, and the lower surface of the graphene layer is arranged
There are OPP dielectric films.
Further, the thickness of the acrylic acid glue-line is 8 12 μm.
Further, the thickness of the OPP dielectric films is 57 μm.
Compared with prior art, this utility model has the advantages that：
Of the present utility model to include graphene layer without base material Graphene heat conducting film, the upper surface of the graphene layer is coated with
Acrylic acid glue-line, the upper surface of the acrylic acid glue-line are pasted with light mould release membrance, and the lower surface of the graphene layer is provided with OPP
Dielectric film.Of the present utility model the characteristics of have heat conductivility high without base material Graphene heat conducting film, heat conductivity can reach
1700-1900W/m-K；The characteristics of there is surface insulation simultaneously, even if flexure plane patch thing can also reach good heat-conducting effect,
And the characteristics of there is low cost, be easy to manufacture.
Description of the drawings
Fig. 1 is structural representation of the present utility model；
Labelling in figure：1st, graphene layer, 2, acrylic acid glue-line, 3, light mould release membrance, 4, OPP dielectric films.
Specific embodiment
