Embodiment
For making this novel structure, feature, effect and purpose that more detailed understanding can be arranged, now coordinate graphic this novel related embodiment to be described in detail as follows.
See also Fig. 1, Fig. 1 is the schematic diagram of the stacked structure of this novel embodiment flexible graphite paper material.
As shown in Figure 1, the stacked structure 10 of flexible graphite paper material comprises the first layer of spacer material 10a, the second layer of spacer material 10b and polyimide film 10c.
According to the stacked structure 10 of above-mentioned flexible graphite paper material, the producer can be used to make graphite paper.Specifically, when making graphite paper, the producer can prepare the first layer of spacer material 10a and the second layer of spacer material 10b in advance.The first layer of spacer material 10a and the second layer of spacer material 10b are material with carbon element layer, metal material layer or ceramic material layer.Wherein, the material with carbon element layer is graphite flake layer, graphite flaggy or carbon dust layer; Metal material is sheet-metal layers or metal bisque.For example, metal material layer is that fusing point is at the sheet-metal layers more than 2000 ℃ or metal bisque; Ceramic material layer is oxide skin(coating), nitride layer, boride layer or carbide lamella.For example, ceramic material is that fusing point is at the oxide skin(coating) more than 2000 ℃, nitride layer, boride layer or carbide lamella.
Then, polyimide film 10c is configured between the first layer of spacer material 10a and the second layer of spacer material 10b to form the stacked structure 10 of flexible graphite paper material.
Particularly, the producer can be in advance (utilizing artificial or machine) with the raw material of the first layer of spacer material 10a, polyimide film 10c and the second layer of spacer material 10b stacked arrangement sequentially, and the stacked structure 10 of this flexible graphite paper material is sent into a high temperature graphitization stove heat-treat to make flexible graphite paper.
By using the high temperature graphitization stove to utilize above-mentioned the first layer of spacer material 10a and the second layer of spacer material 10b to press.Be heated to 3000 ℃ by room temperature.In this embodiment, but be not limited to, heated by the stepwise heating mode, also can be directly be heated between 2400 ℃ to 3000 ℃ of temperature by room temperature.The stepwise heating mode, particularly, in the time of can being heated to (comprise 1000 ℃) below 1000 ℃ by room temperature, heating per minute be no more than 2 ℃, and when being heated to more than 1000 ℃ (comprise 3000 ℃) below 3000 ℃, heating per minute is no more than 10 ℃.When the stepwise heating mode is adopted in heat treatment, utilize the first layer of spacer material 10a and the second layer of spacer material 10b also can control the foaming degree of polyimide film 10c in heat treatment process.
For example, in heat treatment process, can have the denitrogenation effect when being heated due to the raw material of polyimide film 10c, thereby produce foamed phenomenon.Therefore, utilize the first layer of spacer material 10a and the second layer of spacer material 10b can help the foaming degree of polyimide film 10c in heat treatment process, make foamed phenomenon can be subject to suitable control.And after completing heat treatment, obtain the flexible graphite paper with uniform in foaming.That is to say, the stacked structure 10 of flexible graphite paper material carries out can becoming flexible graphite paper after above-mentioned heat treatment process.
Wherein, made flexible graphite paper comprises material with carbon element layer, metal material layer or ceramic material layer.Described material with carbon element layer, metal material layer or ceramic material layer are formed on the surface (for example: upper surface or lower surface, but be not limited to this) of flexible graphite paper.
In addition, by changing the first layer of spacer material 10a and the second layer of spacer material 10b, can make simultaneously different polyimide film (carbonization polyimide film).Or change weight and the material of the first layer of spacer material 10a and the second layer of spacer material 10b, and come optionally polyimide film 10c to be exerted pressure, also can improve so make yield.
That is to say, utilize the first layer of spacer material 10a and the second layer of spacer material 10b can help the foaming degree homogenizing of polyimide film 10c when heat-treating program.
See also Fig. 2, Fig. 2 is the schematic diagram of the stacked structure of this novel another embodiment flexible graphite paper material.
As shown in Figure 2, the difference of Fig. 2 and Fig. 1 is: the stacked structure of sequentially arranging to form the flexible graphite paper material with more the first layer of spacer material 10a, the second layer of spacer material 10b and polyimide film 10c.
Hence one can see that, dispose the stacked structure of polyimide film 10c between the first layer of spacer material 10a (or second layer of spacer material 10b) and the second layer of spacer material 10b (or first layer of spacer material 10a), its stacking number of plies can be decided according to actual demand, is not limited to the number of plies of Fig. 1 and Fig. 2.
The stacked structure of the described flexible graphite paper material of this new embodiment has following characteristics: but utilize the first layer of spacer material and the foaming degree of the second layer of spacer material homogenizing polyimide film in heat treatment process, to promote the thermal conductivity of making rear flexible graphite paper.
In sum, above embodiment for this novel preferred embodiment of enumerating, is not only the scope that limits this novel enforcement.Be that the equalization that the novel claim of Fan Yiben is done changes and modifies, be all this new patent protection range and contain.Protection range of the present utility model is as the criterion with claims.
