Description
Technical field
This utility model relates to a kind of heat conducting film.
Background technology
At present, heat-conducting glue adhesive tape all uses PE (polyethylene) thin film to use as base material, and PE film strength is poor, increase
Add intensity and must increase film thickness, affect heat conductivity, and the heat-resisting quantity of PE film is poor.And this processing film is more complicated,
Production efficiency is low, relatively costly.
Utility model content
Technical problem to be solved in the utility model is, for the deficiencies in the prior art, it is provided that a kind of light heat conducting film, with
Reach to improve heat conductivility, purpose easy to process.
For solving above-mentioned technical problem, the technical solution of the utility model is: a kind of heat conducting film, including layers of copper, described
Layers of copper is respectively provided on two sides with heat-conducting layer, and wherein heat-conducting layer surface in side is provided with insulating barrier, and opposite side heat-conducting layer surface is provided with gluing
Layer, described glue adhesion coating surface is provided with release film layer.
Described heat-conducting layer is graphite film layer.
Described insulating barrier is rubber layer.
This utility model uses said structure, have the advantage that 1, heat conductivity is good, thermal coefficient of expansion is little, good
Dimensional stability；2, have that coating is good, the strong and easy processing characteristic of plasticity；3, can design with bound edge during graphite film layer cross cutting,
Graphite film layer is made to have good insulating properties；4, to clung bodies such as graphite film and mobile phone shell on the back, cell phone mainboard, rustless steel fin
All there is good insulating properties.
Accompanying drawing explanation
With detailed description of the invention, this utility model is described in further detail below in conjunction with the accompanying drawings；
Fig. 1 is lamination layer structure schematic diagram of the present utility model；
In FIG, 1, layers of copper；2, heat-conducting layer；3, insulating barrier；4, glue adhesion coating；5, release film layer.
Detailed description of the invention
A kind of heat conducting film as shown in Figure 1, including layers of copper 1, described layers of copper 1 is respectively provided on two sides with heat-conducting layer 2, wherein side
