Description
Technical field
The present invention relates to graphite product field of deep, and in particular to a kind of electromagnetic shielding knot prepared using graphite paper
Structure.
Background technique
The application of a large amount of electronic equipments, so that electromagnetic interference and electromagnetic radiation pollution have become a kind of environmental hazard.Electromagnetic interference
It will lead to various electronic equipments to be unable to operate normally, the electromagnetic radiation of generation passes through pyrogenic action, non-thermal effect, lag and accumulation
Effect causes injury directly or indirectly to human body.
Using conductive or permeability magnetic material to the good reflection of electromagenetic wave radiation and absorbent properties, as electromagnetic shielding
Functional motif material prepares filled-type electromagnetic wave shielding composite material, generates electricity by conductive or permeability magnetic material in composite material
It is thermal energy that loss, dielectric loss and magnetic loss etc., which are led, by electromagnetic energy, can effectively weaken electromagnetic radiation.
Summary of the invention
A kind of electromagnetic armouring structure prepared using graphite paper provided by the invention, can effectively reduce or weaken electromagnetism spoke
It penetrates.
In order to solve the above technical problems, the technical scheme adopted by the invention is that: a kind of electromagnetism prepared using graphite paper
Shielding construction, including the first graphite paper layer, supporting network and the second graphite paper layer from top to bottom set gradually, first graphite
Paper layer and the second graphite paper layer with a thickness of 0.5-1.5mm.
Further, it between the first graphite paper layer and supporting network, is equipped between supporting network and the second graphite paper layer
Conductive adhesive layer.The fixed bonding of three is realized by conducting resinl.
Further, the conductive adhesive layer with a thickness of 0.2-1mm.
Further, the thickness of the first graphite paper layer and the second graphite paper layer is 1mm.
Further, the supporting network is metal support network, and mesh size is 75-150 microns.
Further, the supporting network is copper supporting network.
The invention has the following advantages:
1) due to the structure using double-layer graphite paper and intermediate course supporting network, certain toughness can be made it have, it is not easy to break
It is disconnected；When in particular by metal support network, not only there is supporting role, can be improved its intensity and toughness, moreover it is possible to enhancing shielding
Effect, wherein use copper supporting network when effect it is best.
2) press compression moulding can be used between double-layer graphite paper and the supporting network of intermediate course, and conducting resinl can also be used
It pastes and fixes.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
