Description
Technical field
The present invention relates to field of cable technology, a kind of super soft mineral insulated cable of graphene is particularly related to.
Background technology
The structure of conventional insulator cable is generally two layers, and internal layer is metal conducting layer, and outer layer is non-metallic insulation layer.So
Cable be only used for common place, and, easy aging inflammable with insulating barrier, it is difficult to be resistant to high temperature, the short grade of service life lacks
Point.
Generally using copper as conductive layer in cable, and copper is easily aoxidized and corroded in itself, and copper quality compared with
Soft, ductility is not good.In the prior art, in order to solve the problem of copper is oxidized and corroded, generally carried out on the surface of conductive copper
Electroplating processes, plate the oxidation resistant material of last layer.But this electroplating technology causes the raising of cable production cost, and easily
Pollute environment.In order to strengthen the ductility of cable, can resist bending be set between conductor and insulating barrier, with good ductility
Material layer.But this material needs to consider cost and performance, it is not easy to find.Therefore, insulated cable one at present on the market
As be difficult to while having good electric conductivity and stronger anti-flammability.

Matter can not be passed through.Therefore acidproof, resistance to oxidation.In all material, it has highest carrier transport speed, and its electronics is passed
Conductance 15000cmol/L/ (V.s), superpower resistance to high current ability is a kind of excellent conductor.In addition, grapheme material can be with
It is mixed into well in other materials so that corrosion-resistant, wearability that the material of synthesis has had.
Graphene-structured is highly stable, so far, and researcher does not have found the situation for having carbon atom to lack in graphene yet.
Connection in graphene between each carbon atom is very flexible, when apply external mechanical force when, carbon atom face with regard to flexural deformation so that
Make carbon atom to be rearranged to adapt to external force, be also maintained for Stability Analysis of Structures.The lattice structure of this stabilization makes carbon atom
With outstanding electric conductivity., will not be because of lattice defect or introducing foreign atom when electronics in graphene is moved in track
Scatter.Because interatomic force is very strong, at normal temperatures, even if surrounding carbon atom is telescoped, electronics in graphene
The interference being subject to is also very small, meanwhile, graphene be in the world it is most thin be also most hard nano material, it is almost fully transparent
, the light of an absorption 2.3%；Thermal conductivity factor is up to 5300W/ (mK), higher than CNT and diamond, its electronics under normal temperature
Mobility is and higher than CNT or silicon crystal more than 15000cm2/ (Vs), and resistivity only about 10-6 Ω cm, compares copper
It is the minimum material of world resistivity or silver is lower.Because its resistivity is extremely low, the speed that electronics is run is exceedingly fast, and graphene is
The best material of electric conductivity in the world, the movement velocity of electronics wherein has reached the 1/300 of the light velocity, existed considerably beyond electronics
Movement velocity in general conductor.
In the field of communications, some cables it is also desirable to have higher anti-interference, and conventional cable is typically set
Conductor shield and insulation screen are equipped with, to reach the effect of homogenizing electric field.But existing screen layer is typically in rubber
Middle addition conductive carbon black.Distribution, size and the carbon black of carbon black granules and the fusion degree of rubber all affect anti-jamming effectiveness.
