Description
Technical field
The present invention relates to a kind of new material and manufacture device, particularly a kind of monocrystal graphite material preparation facilities, belong to
New material preparation field.
Background technology
In recent years, along with science and technology flourish, the service behaviour of electronic product is the most elevated, and electronic product
Size more and more less, and the raising of operating rate and the efficiency along 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 time produced heat energy, thereby ensure that electronics
Product energy normal operation, and then the reliability enhanced product performance and extend service life of product.
To this, graphite flake (Graphite Sheet) 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, the most become 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, the most 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 first natural graphite flakes must be carried out acidification and company
Continuous high-temperature calcination, to produce fluffy of graphite, then stands fluffy special time of graphite to move back temperature taking-up.Afterwards, also
Must 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 at single
The preparation process of graphite flake, is only capable of obtaining a graphite flake, and such repeatable operation will take for substantial amounts of preparation time, and this will make stone
The capacity efficiency of ink sheet cannot improve.
Such as the preparation method of 201310369027.3 1 kinds of nano graphite flakes of Patent No., it is former with natural flake graphite
Material, uses oxidant and intercalator to carry out natural flake graphite aoxidizing intercalation processing, forms intercalation expansible graphite, use micro-
Intercalation expansible graphite is carried out expanded by Wave heating mode, forms expanded graphite, thereafter, in organic solvent, uses ultrasonic spoke
Nano graphite flakes is formed according to expanded graphite is carried out stripping；The inventive method is simple to operate, and efficiency is high, and safety is good, expands all
Even；Prepared its a diameter of 0.5～20 μm of nano graphite flakes, thickness is 0.35～50nm, average thickness 35nm, peels off journey
Degree height, has roll-shaped, curling S-shaped, concavo-convex agglomerate shape different-shape, and heat conductivility is good, the most easily disperses.
The and for example preparation method of 201410122837.3 1 kinds of graphite flakes of Application No., including providing 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, the first graphite flake to be separated into second and third graphite flake in uniform thickness,
The second graphite flake after compacting separates afterwards, and stick on the parting surface of the 3rd release base material the second graphite flake after compacting,
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 sheet
Between, and also preparation flow can be simplified, reduce cost and reduce pollution.
Both the above preparation method the most all have impact on physical aspect and the chemical form of graphite flake crystal, the graphite prepared
Deviation characteristically can be deposited.
