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 the low-density characteristic relative to metal fin, and tool
There are the characteristics such as high heat dissipation/heat conduction, the anticorrosive and low thermal resistance of insulation, has become that electronic product is helped to realize quick dissipate at present
The preferred material of heat/heat conduction.Graphite flake can also vertically carry out heat conduction, especially in addition to that can carry out heat conduction along level
Graphite flake is laminar structured, therefore more can be suitably used for the surface of any product, in favor of reaching the work of more preferably heat dissipation/heat conduction
With.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.
