Description
Technical field
The present invention relates to a kind of material manufacturing apparatus, particularly a kind of graphite material minimal thickness paving pressing molding device, belong to
New material preparation field.
Background technology
In recent years, with scientific and technological flourish, the service behaviour of electronic product is constantly elevated, and electronic product
Size also less and less, and the raising of operating rate and the efficiency with electronic product, this also means that sending out of electronic product
Heat is increasing, and therefore electronic product not only needs to be equipped with corresponding heat abstractor, it is also to be ensured that heat abstractor has excellent
Heat-sinking capability, with in time remove within electronic product electronic building brick work when produced heat energy, thereby ensure that electronics
Product energy normal operation, and then the service life of the reliability enhanced product performance and prolongation product.
In this regard, graphite flake (Graphite Sheet) is because having the low-density characteristic relative to metal fin, and
There is the characteristic such as high heat radiation/heat conduction, the anticorrosive and low thermal resistance of insulating, become at present to help electronic product to realize soon
The preferred material of speed heat radiation/heat conduction.Graphite flake, except carrying out heat conduction along level, also can vertically carry out heat conduction,
Particularly graphite flake is laminar structured, therefore more can be suitably used for the surface of any product, be beneficial to reach more preferably to dispel the heat/
The effect of heat conduction.But, in the preparation process of traditional graphite flake, generally must first natural graphite flakes be acidified
Processing and continuous high temperature is calcined to produce fluffy of graphite, then standing fluffy special time of graphite to move back temperature taking-up.
Afterwards, must also be by fluffy for the graphite graphite flake being rolled into predetermined thickness, to complete the preparation of graphite flake.It should be noted that
In the preparation process of single graphite flake, being only capable of obtaining a graphite flake, operation so repeatedly will take for substantial amounts of preparation time, this
The capacity efficiency making graphite flake cannot be improved.
Such as the preparation method of 201310369027.3 1 kinds of nano graphite flakes of Patent No., with natural flake graphite as raw material, adopt
Carry out aoxidizing intercalation processing to natural flake graphite with oxidant and intercalator, form intercalation expansible graphite, use microwave to add
Intercalation expansible graphite is carried out expanded by hot mode, forms expanded graphite, thereafter, in organic solvent, uses ultrasound wave irradiation pair
Expanded graphite carries out stripping and forms nano graphite flakes；The inventive method is simple to operate, and efficiency is high, and security is good, expands uniformly；Institute
The nano graphite flakes prepared its a diameter of 0.5～20 μm, thickness is 0.35～50nm, average thickness 35nm, and extent of exfoliation is high,
Having roll-shaped, curling S-shaped, concavo-convex agglomerate shape different-shape, heat conductivility is good, easily disperses in organic solvent.
The and for example preparation method of 201410122837.3 1 kinds of graphite flakes of Application No., including provide the first graphite flake, and
And stick first and second release base material on first and second surface of the first graphite flake, then along the of the first graphite flake
One side separates first and second release base material, so that the first graphite flake to be separated into second and third graphite flake in uniform thickness,
Afterwards compacting separate after the second graphite flake, and stick the 3rd release base material in compacting after the second graphite flake parting surface on,
So that along second side separation first and the 3rd release base material of the second graphite flake, and then it is equal that the second graphite flake is separated into thickness
The the 4th and the 5th even graphite flake.When the preparation method of graphite flake proposed by the invention can reduce the preparation of conventional graphite piece
Between, and also preparation flow can be simplified, reduce cost and reduce pollution.
Both the above preparation method all have impact on physical aspect and the chemical form of graphite flake crystal, the graphite prepared
Deviation characteristically can be deposited.
