Abstract
The invention discloses novel insulating graphite. The novel insulating graphite comprises a graphite substrate and an insulating layer, wherein the insulating layer is arranged on one surface of the graphite substrate and is integrated with the graphite substrate in a bonding or plating or coating mode. The graphite substrate and the insulating layer are integrated, the graphite substrate conducts heat but does not conduct electricity through the good and stable insulating performance of the insulating layer, the insulating performance of the novel insulating graphite is improved while the novel insulating graphite has heat conduction and radiation performance, the use performance of electronic product components is guaranteed, the service life of the electronic product components 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:
A kind of New insulated graphite, comprise graphite matrix and insulating barrier, described insulating barrier is arranged at the one side of described graphite matrix, and is molded as one by stickup, coating or coating and described graphite matrix.
Preferably, described graphite matrix is artificial graphite flake.
Pass through technique scheme, New insulated graphite provided by the invention, by graphite matrix and insulating barrier are molded as one, utilize the insulating properties that insulating barrier is good and stable, make graphite matrix heat conduction and non-conductive, and then make this New insulated graphite 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.
