Abstract
The invention discloses novel insulating graphite. The novel insulating graphite comprises a graphite matrix and an oxide layer, wherein the oxide layer is arranged on one side of the graphite matrix and is integrally formed with the graphite matrix through a plating or coating. The graphite matrix and the oxide layer are integrally formed, and the oxide layer has good insulation, so that the insulating graphite is heat-conducting but non-conducting, further the insulation performance of the graphite is enhanced during heat conduction and heat dissipation, the service performance of electronic product members is guaranteed, the service life of the members is prolonged, and great convenience is brought to enterprises.
Description
Technical field
The present invention relates to insulating material application, particularly a kind of New insulated graphite of heat conduction and heat radiation.
Background technology
In recent years, along with the development of electronic technology, the continuous renewal of electronic product is regenerated, the size of its work package is more and more less, speed and the efficiency of work are more and more higher, its caloric value is also increasing, therefore often adopts graphite heat radiation fin as the preferred material solving electronic product heat conduction and heat radiation.Graphite heat radiation fin also has conductivity while having good heat conduction and heat radiation performance, and some components of electronic product inside need insulation, and therefore independent utilization graphite heat radiation fin cannot reach the effect of insulation.
In prior art, usually a glued membrane is pasted in the one side of graphite heat radiation fin, to reduce its conductivity, but, the insulating properties of glued membrane is not very good, and it still there will be the phenomenon of conduction or local conduction, will certainly affect the serviceability of mobile phone part like this, even can shorten the useful life of component, bring very large inconvenience to enterprise.
Summary of the invention
For solving Problems existing in above-mentioned background technology, the object of the present invention is to provide a kind of New insulated graphite, to reach the heat conduction and heat radiation performance that both make use of graphite, in turn enhancing the object of its insulation property.
For achieving the above object, technical scheme of the present invention is as follows:
New insulated graphite, comprises graphite matrix and oxide layer, and described oxide layer is arranged at the one side of described graphite matrix, and by coating or coating and described graphite matrix be molded as one.
Preferably, described graphite matrix is artificial graphite flake.
Preferably, described oxide layer is metal oxide or nonmetal oxide.
Pass through technique scheme, New insulated graphite provided by the invention, by graphite matrix and oxide layer are molded as one, the good insulating properties utilizing oxide layer to have, make this insulation graphite heat conducting and non-conductive, and then make it while heat conduction and heat radiation, enhance its insulation property, ensure the serviceability of electronic product component, extend its useful life, bring great convenience to enterprise.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below.
Fig. 1 is the perspective view of embodiment of the present invention New insulated graphite.
In figure, number designation represents the title of parts:
1, electrographite sheet 2, oxide layer
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described.
Embodiment one:
New insulated graphite provided by the invention, as shown in Figure 1, comprise electrographite sheet 1 and oxide layer 2, oxide layer 2 is arranged at the one side of electrographite sheet 1 and is molded as one by the mode of coating and electrographite sheet 1, oxide layer is metal oxide or nonmetal oxide, its material is chosen as aluminium oxide, cupric oxide or silica, boron oxide, further reaches good insulation effect.
Embodiment two:
New insulated graphite provided by the invention, as shown in Figure 1, comprise electrographite sheet 1 and oxide layer 2, oxide layer 2 be arranged at electrographite sheet 1 one side and by coating mode and electrographite sheet 1 be molded as one, oxide layer is metal oxide or nonmetal oxide, its material is chosen as aluminium oxide, cupric oxide or silica, boron oxide, further reaches good insulation effect.
New insulated graphite disclosed by the invention, by graphite matrix and oxide layer are molded as one, the good insulating properties utilizing oxide layer to have, make this insulation graphite heat conducting and non-conductive, and then make it while heat conduction and heat radiation, enhance its insulation property, ensure the serviceability of electronic product component, extended its useful life, bring great convenience to enterprise; Meanwhile, this New insulated graphite not only structure is simple but also with low cost, and result of use is remarkable.
