Description

A kind of slim graphite flake manufacture and graphite monocrystal extract integrated device

Technical field

This utility model is related to a kind of material manufacturing apparatus, and particularly a kind of slim graphite flake manufacture and graphite monocrystal are carried Integrated device is taken, belongs to new material preparation field.

Background technology

In recent years, flourishing with science and technology, the service behaviour of electronic product is constantly elevated, and electronic product Size it is also less and less, and the raising of the operating rate with electronic product and efficiency this also means that sending out for electronic product Heat is increasing, therefore electronic product not only needs to be equipped with corresponding heat abstractor, it is also to be ensured that heat abstractor have it is excellent Heat-sinking capability, in time to remove heat energy produced when electronic building brick inside electronic product works, thereby ensure that electronics 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 With high radiating/heat conduction, insulate the characteristics such as anticorrosive and low thermal resistance, becomes at present to help electronic product to realize soon The preferred material of fast radiating/heat conduction.Graphite flake can vertically carry out heat conduction except carrying out heat conduction along level, also, Particularly graphite flake is for laminar structured, therefore more can be suitably used for the surface of any product, be beneficial to reach more preferably radiating/ The effect of heat conduction.However, in the preparation process of traditional graphite flake, generally first must be acidified to natural graphite flakes Process and continuous high temperature is calcined to produce fluffy of graphite, fluffy special time of graphite is then stood to move back warm taking-up. Afterwards, the graphite flake that must also be rolled into predetermined thickness by graphite fluffy, to complete the preparation of graphite flake.It should be noted that In the preparation process of single graphite flake, it is only capable of obtaining a graphite flake, such repeatable operation will take for substantial amounts of preparation time, this The capacity efficiency for causing graphite flake cannot be improved.

As a kind of 201310369027.3 nano graphite flakes of Patent No. preparation method, with natural flake graphite as original Material, carries out oxidation intercalation processing using oxidant and intercalator to natural flake graphite, forms intercalation expansible graphite, using micro- Wave heating mode intercalation expansible graphite is carried out it is expanded, formed expanded graphite, thereafter, in organic solvent, using ultrasonic spoke According to stripping being carried out to expanded graphite form nano graphite flakes；The inventive method is simple to operate, efficiency high, and safety is good, and expansion is equal It is even；Its a diameter of 0.5～20 μm of prepared nano graphite flakes, thickness are 0.35～50nm, average thickness 35nm, peel off journey Degree is high, and with roll-shaped, curling S-shaped, concavo-convex agglomerate shape different-shape, heat conductivility is good, easily disperses in organic solvent.

A kind of and for example preparation method of 201410122837.3 graphite flake 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, and the first graphite flake is separated into second and third graphite flake in uniform thickness, The second graphite flake after compacting is separated afterwards, and stick the 3rd release base material on the parting surface of the second graphite flake after compacting, So as to the second side separation first along the second graphite flake and the 3rd release base material, 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, reduces cost and reduction are polluted.

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.
