Abstract
The utility model discloses a novel insulation graphite comprising a graphite base body and an oxide layer. The oxide layer is arranged on one face of the graphite base body and is integrated with the graphite base body through plating or coating. Since the graphite base body is integrated with the oxide layer and the good insulation performance of the oxide layer is utilized, the graphite base body is heat-conductive but not electricity-conductive, the insulation performance of the graphite base body is enhanced during heat conduction and heat dissipation, the usage performance of electronic product component is guaranteed, service life of the insulation graphite is prolonged, and great convenience is brought forward to enterprises.
Description
Technical field
The utility model relates to the insulating material application, the New insulated graphite that particularly a kind of heat conduction and heat radiation is used.
Background technology
In recent years, development along with 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 that solves the electronic product heat conduction and heat radiation.Graphite heat radiation fin also has conductivity when having good heat conduction and heat radiation performance, and some members of electronic product inside need insulation, and therefore independent utilization graphite heat radiation fin can't reach the effect of insulation.
In prior art, usually paste a glued membrane in the one side of graphite heat radiation fin, to reduce its conductivity, yet, the insulating properties of glued membrane is not very good, and it still there will be conduction or local phenomenon of conducting electricity, and will certainly affect like this serviceability of mobile phone part, even can shorten the useful life of member, to enterprise, bring very large inconvenience.
The utility model content
For solving the problem existed in the above-mentioned background technology, the purpose of this utility model is to provide a kind of New insulated graphite, to reach the heat conduction and heat radiation performance of both having utilized graphite, has strengthened again the purpose of its insulation property.
For achieving the above object, the technical solution of the utility model is as follows:
New insulated graphite, comprise graphite matrix and oxide layer, and described oxide layer is arranged at the one side of described graphite matrix, and be shaped to one by coating or coating and described graphite matrix.
Preferably, described graphite matrix is artificial graphite flake.
Preferably, described oxide layer is metal oxide or nonmetal oxide.
Pass through technique scheme, the New insulated graphite that the utility model provides, by graphite matrix and oxide layer are shaped to one, the good insulating properties of utilizing oxide layer to have, make this insulation graphite heat conducting and non-conductive, and then make it strengthen its insulation property in heat conduction and heat radiation, ensured the serviceability of electronic product member, extend its useful life, bring great convenience to enterprise.
The accompanying drawing explanation
