Description
Technical field
The present invention relates to a kind of material manufacturing apparatus, especially a kind of graphite material thin thickness spreads pressing molding device, belongs to
New material preparation field.
Background technology
In recent years, flourishing with science and technology, the working performance of electronic product is constantly elevated, and electronic product
Size it is also smaller and smaller, and the raising of the operating rate and efficiency with electronic product, this also means that the hair of electronic product
Heat is increasing, therefore electronic product not only needs to be equipped with corresponding radiator, it is also to be ensured that radiator is with excellent
Heat-sinking capability thereby ensure that electronics in time to remove generated thermal energy when electronic building brick inside electronic product works
Product energy normal operation, and then the reliability enhanced product performance and the service life for extending product.
In this regard, graphite flake (Graphite Sheet) is because with low-density characteristic relative to metal fin, and
With high heat dissipation/heat conduction, insulate the characteristics such as anticorrosive and low thermal resistance, has become that electronic product is helped to realize soon at present
The preferred material of fast heat dissipation/heat conduction.Graphite flake in addition to can along level carry out heat conduction, can also vertically carry out heat conduction,
Especially graphite flake is laminar structured, therefore more can be suitably used for the surface of any product, in favor of reach more preferably heat dissipation/
The effect of heat conduction.
However, in the preparation process of traditional graphite flake, usually must acidification and company first be carried out to natural graphite flakes
Continuous high-temperature calcination then stands fluffy specific time of graphite to move back warm taking-up to generate fluffy of graphite.Later, also
It must be by fluffy graphite flake for being rolled into predetermined thickness of graphite, to complete the preparation of graphite flake.It is worth noting that, in single
The preparation process of graphite flake is only capable of obtaining a graphite flake, and operation repeatedly will spend a large amount of preparation time, this will be so that stone
The capacity efficiency of ink sheet can not improve.
It is original with natural flake graphite such as a kind of preparation method of 201310369027.3 nano graphite flakes of Patent No.
Material carries out oxidation intercalation processing to natural flake graphite using oxidant and intercalator, forms intercalation expansible graphite, and use is micro-
Wave heating mode carries out intercalation expansible graphite puffing, formation expanded graphite, thereafter, in organic solvent, using ultrasonic spoke
Nano graphite flakes are formed according to stripping is carried out to expanded graphite；The method of the present invention is easy to operate, efficient, and safety is good, and expansion is equal
It is even；A diameter of 0.5~20 μm of prepared nano graphite flakes, thickness are 0.35~50nm, average thickness 35nm, remove journey
Degree is high, has roll-shaped, curling S-shaped, concave-convex agglomerate shape different-shape, heat conductivility is good, is easy dispersion in organic solvent.
For another example application No. is a kind of 201410122837.3 preparation methods of graphite flake, 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
A side detaches first and second release base material, and the first graphite flake is separated into second and third graphite flake in homogeneous thickness,
The second graphite flake after compacting separation later, and stick on the parting surface of the second graphite flake of the release base material of third after compacting,
So as to along the second side of the second graphite flake separation first and the release base material of third, 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 can also simplify preparation flow, reduce cost and reduce pollution.
Both the above preparation method all affects the physical aspect and chemical form of graphite flake crystal, the graphite prepared
Deviation characteristically can be deposited.
Invention content
The technical problem to be solved in the invention is that in view of the above shortcomings of the prior art, and it is thin to provide a kind of graphite material
Thickness spreads pressing molding device.
In order to solve the above technical problems, the technical solution adopted by the present invention is

It is inside provided with thinning apparatus, the thinning apparatus includes main shaft, connects the main shaft and is provided with two lever arms, described in two
Lever arm is respectively hinged on main shaft, and the lever arm described in two can be relatively movable, and the end set of the lever arm has blade,
It is provided with graphite dust outlet and adhesive outlet on the blade, hold-down devices are provided on the main shaft.
As further preferred embodiment, the blade on two lever arms can be connected with each other, the blade
A long side be arc surface, graphite dust outlet and adhesive outlet are located on arc surface, and blade is rotated in preparation vessel
It promotes, arc surface is the one side promoted.
As further preferred embodiment, the side wall of the section of the blade apart from preparation vessel has gap.
As further preferred embodiment, the lever arm is L-shaped structure, and longer part connects main shaft, compared with
Short part connects blade.
As further preferred embodiment, the width of the blade is the 1/5-1/10 of its length.
Advantageous effect
Compared with prior art, a kind of graphite material thin thickness of the invention spreads pressing molding device, passes through two lever arms
Relative rotation, drive blade that graphite solution is laid in preparation vessel, then pushed, obtain the graphite sheet of thin thickness,
Specifically has the following advantages：
