Material and preparation method thereof.
Background technique
For electronic product in order to improve heat-sinking capability, the graphite material with strong heat-sinking capability becomes more and more producers at present
First choice.Synthetic graphite and guiding principle rice crystalline substance material prepare compound heat sink material, usually in nanocrystalline upper sticking two-faced adhesive tape, then
Synthetic graphite is pasted on double-sided adhesive, then by rolling fitting, is bonded nanocrystalline consolidate with synthetic graphite.This preparation side
Formula, easy to process, the composite material of formation also has certain heat dissipation performance.However, due to the presence of double-sided adhesive, and it is two-sided
Glue has certain thickness, causes the thickness of entire material larger.For the electronic product towards lightening trend development, further
Frivolous heat dissipation product can be conducive to the more lightening of entire design of electronic products.In addition, the heat resistance of double-sided adhesive compared with
A left side, and double-sided adhesive is in centre, can also stop the transmitting of heat to a certain extent, to influence whole heat dissipation performance.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of nanocrystalline and synthetic graphite adhesion without adhesiver composite material and its systems
Preparation Method, magnetic conductivity with higher have lesser magnetic loss, heating conduction with higher in high frequency.
In order to solve the above-mentioned technical problem, the present invention takes following technical scheme:
A kind of nanocrystalline preparation method with synthetic graphite adhesion without adhesiver composite material, comprising the following steps:
Nanocrystalline raw material are put as being heated to molten condition in vacuum environment；
The operation mode that the nanocrystalline material of molten condition is got rid of to band is ejected into the synthetic graphite surface transmitted by roll shaft,
Synthetic graphite passes through the complex of formation amorphous magnetic material and synthetic graphite behind cooling zone；
The annealing that the complex of amorphous magnetic material and synthetic graphite is passed through to 500-600 DEG C keeps the amorphous fraction of complex brilliant
Change；
Complex is subjected to natural cooling, is sent into press pressing, obtain it is nanocrystalline in conjunction with synthetic graphite after composite material.
The nanocrystalline material, which is put into frequency induction furnace in a vacuum, to be heated, and being heated to 1200-1400 DEG C of temperature makes
Nanocrystalline is molten state, vacuum degree≤10-2Pa。
The temperature of 3 cooling zones is maintained at -90-110 DEG C.
A kind of nanocrystalline with synthetic graphite adhesion without adhesiver composite material, the composite material includes synthetic graphite and nanocrystalline,
The nanocrystalline and synthetic graphite integrated formed structure.
Present invention straight forming on synthetic graphite is nanocrystalline, and the two is combined as a whole, and reduces intermediate adhesive material, has
Higher magnetic conductivity has lesser magnetic loss in high frequency, and heating conduction with higher, whole thickness is smaller.
Detailed description of the invention
Attached drawing 1 is the diagrammatic cross-section of composite material prepared by the present invention.
Specific embodiment
To further understand the features of the present invention, technological means and specific purposes achieved, function, below with reference to
Present invention is further described in detail with specific embodiment for attached drawing.
Present invention discloses a kind of nanocrystalline preparation methods with synthetic graphite adhesion without adhesiver composite material, including following step
It is rapid:
S1 puts nanocrystalline raw material as molten condition is heated in vacuum environment, is usually to put to incude as vacuum intermediate-frequency
Heating in heating furnace, for nanocrystalline raw material, its melting, vacuum degree≤10 can be made by being heated to 1300 DEG C-2Pa。
The operation mode that the nanocrystalline material of molten condition is got rid of to band is ejected into the synthetic graphite table transmitted by roll shaft
Face, synthetic graphite pass through the complex of formation amorphous magnetic material and synthetic graphite behind cooling zone.Melting nanocrystalline material is got rid of and is taken to
The synthetic graphite surface of high speed conveying, then quickly through cooling zone, so that melting nanocrystalline material molding, the temperature of the cooling zone
Degree is maintained at -90-110 DEG C.
The annealing that the complex of amorphous magnetic material and synthetic graphite is passed through to 500-600 DEG C, makes the amorphous portion of complex
Divide crystallization.After annealing, the amorphous fraction crystallization of amorphous magnetic material.
Complex is subjected to natural cooling, is sent into press pressing, obtain it is nanocrystalline in conjunction with synthetic graphite after composite wood
Material.Complex is placed, is cooled down by natural wind, or can dry and accelerate cooling procedure, after the pressing of press, so that receiving
Meter Jing Yu synthetic graphite combines more firm.
It is prepared according to above-mentioned preparation method, directly in synthetic graphite surface forming nanocrystalline material, guarantees the same of binding force
When, and intermediate adhesive material is eliminated, the transmitting of heat is directly carried out when enabling thermally conductive, moreover, the integral structure of the two,
Ensure that high-termal conductivity, and by get rid of band in the way of by amorphous magnetic material to Crystallizing treatment, it is finally cooling to combine, maintain compound
The high magnetic permeability of material has lesser magnetic loss rate in high frequency.
In addition, as shown in Fig. 1, the composite material being prepared integrally is divided into double-layer structure, respectively synthetic graphite 1
With nanocrystalline 2, the centre of the two does not have an adhesive material, it is thermally conductive more directly.And due to there is no intermediate adhesive material, so that whole
The thickness of body is smaller, can be used in more lightening electronic product.
It should be noted that these are only the preferred embodiment of the present invention, it is not intended to restrict the invention, although ginseng
According to embodiment, invention is explained in detail, for those skilled in the art, still can be to aforementioned reality
Technical solution documented by example is applied to modify or equivalent replacement of some of the technical features, but it is all in this hair
Within bright spirit and principle, any modification, equivalent replacement, improvement and so on should be included in protection scope of the present invention
Within.
