Abstract
The utility model discloses a release graphite flake comprising a graphite substrate, a double-faced adhesive tape and a release film, wherein one side of the double-faced adhesive tape is stuck with the graphite substrate, and the other surface is stuck with the release film; the inner surface of the release film is in a frosted or toothed structure. Because the inner surface of the release film is in the frosted or toothed structure, the contact area between the release film and the double-faced adhesive tape can be reduced, and tension and adhesion in a tearing process are reduced, so that the release film is easy to tear off, and great convenience is brought to enterprises.
Description
Technical field
The utility model relates to heat conduction and heat radiation material application, particularly a kind of release graphite flake.
Background technology
In recent years, development along with electronic technology, the continuous renewal of electronic product is regenerated, the size of its work package is more and more less, speed and the efficiency of work are more and more higher, its caloric value is also increasing, therefore often adopts graphite heat radiation fin as the preferred material that solves the electronic product heat conduction and heat radiation.
In prior art, usually utilize the one side of double faced adhesive tape to paste with graphite heat radiation fin, its another side sticks on electronic product, to facilitate the heat conduction and heat radiation of this product, when the another side of double faced adhesive tape is not on Paste Product, for the another side of convenient double-sided glue is pasted with a mould release membrance usually, when needs stick on product by it, then mould release membrance is torn.Yet, stick at present the equal smoother of inner surface of the mould release membrance on double faced adhesive tape, because its pulling force in the process of tearing is larger, adhesive force is also larger, therefore is not easy to tear, and to enterprise, brings very large inconvenience.
The utility model content
For solving the problem existed in the above-mentioned background technology, the purpose of this utility model is to provide a kind of release graphite flake, to reach, facilitates mould release membrance by the purpose of tearing on double faced adhesive tape.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of release graphite flake, comprise graphite matrix, double faced adhesive tape and mould release membrance, and the one side of described double faced adhesive tape is pasted with described graphite matrix, and another side and described mould release membrance are pasted, and the inner surface of described mould release membrance is set to the frosted shape or is provided with groove.
Preferably, described graphite matrix is artificial graphite flake.
Pass through technique scheme, the release graphite flake that the utility model provides, inner surface by mould release membrance is set to the frosted shape or is provided with groove, reduced the contact area of mould release membrance and double faced adhesive tape, and then reduced its pulling force and adhesive force in the process of tearing, make it be easy to tear, bring great convenience to enterprise.
The accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, below will the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described.
The perspective view that Fig. 1 is the disclosed a kind of release graphite flake of the utility model embodiment;
The structural representation of the mould release membrance inner surface that Fig. 2 is the utility model embodiment mono-disclosed a kind of release graphite flake;
The structural representation of the mould release membrance inner surface that Fig. 3 is the utility model embodiment bis-disclosed a kind of release graphite flakes.
In figure, number designation means the title of parts:
1, electrographite sheet 2, double faced adhesive tape 3, mould release membrance
The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.
Embodiment mono-:
A kind of micanite ink sheet that the utility model provides, as shown in Figure 1-2, comprise electrographite sheet 1, double faced adhesive tape 2 and mould release membrance 3, and the one side of double faced adhesive tape 2 is pasted with electrographite sheet 1, and another side and mould release membrance 3 are pasted, and the inner surface of mould release membrance 1 is set to the frosted shape.
Embodiment bis-:
A kind of micanite ink sheet that the utility model provides, as shown in Figure 1, Figure 3, comprise electrographite sheet 1, double faced adhesive tape 2 and mould release membrance 3, and the one side of double faced adhesive tape 2 is pasted with electrographite sheet 1, and another side and mould release membrance 3 are pasted, and the inner surface of mould release membrance 1 is provided with groove.
The disclosed a kind of release graphite flake of the utility model, inner surface by mould release membrance is set to the frosted shape or is provided with groove, reduced the contact area of mould release membrance and double faced adhesive tape, and then reduced its pulling force and adhesive force in the process of tearing, make it be easy to tear, bring great convenience to enterprise; Simultaneously, this release graphite flake is not only simple in structure, with low cost, and result of use is remarkable.
To the above-mentioned explanation of the disclosed embodiments, make professional and technical personnel in the field can realize or use the utility model.Multiple modification to these embodiment will be apparent for those skilled in the art, and General Principle as defined herein can be in the situation that do not break away from spirit or scope of the present utility model, realization in other embodiments.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
Claims (2)
1. a release graphite flake, comprise graphite matrix, double faced adhesive tape and mould release membrance, and the one side of described double faced adhesive tape is pasted with described graphite matrix, and another side and described mould release membrance are pasted, and it is characterized in that, the inner surface of described mould release membrance is set to the frosted shape or is provided with groove.
2. a kind of release graphite flake according to claim 1, is characterized in that, described graphite matrix is artificial graphite flake.
