Current social electronics, electrical equipment and communication industry development are rapid, and increasing electric equipment products has been come into huge numbers of families.These products have improved people's living standard on the one hand, have also brought a kind of special environmental pollution on the other hand, i.e. electromagnetic pollution.Using the absorbing material with electromagnetic wave attenuation function in electronic product is the effective way that alleviates electromagnetic pollution.
Absorbing material is meant a class material that can effectively absorb incident electromagnetic wave and make its decay, and it changes into heat energy or other form of energy to reach the purpose of inhaling ripple by different loss mechanism with incident electromagnetic wave.In the absorbing material, patch-type absorbing material thin thickness, easy to use, for reducing electromagnetic radiation, preventing that electromagnetic interference from having good effect, relatively is fit to be applied in the electronic product.And the main flow trend of electronic product development is microminiaturized, Highgrade integration, and the product inner space is narrow and small relatively.Therefore, how to make thin thickness, the outstanding paster material of absorbing property and become the focus that people pay close attention to.
Summary of the invention
The utility model provides a kind of pad pasting that is used for electromagnetic wave attenuation, and this pad pasting effectively absorbs electromagnetic wave and significantly improves the effect that its proof voltage punctures simultaneously.
For achieving the above object, the technical solution adopted in the utility model is: a kind of pad pasting that is used for electromagnetic wave attenuation comprises insulating barrier, the graphite linings as the reflector, absorbed layer and separated type material layer; Be disposed with first adhesive layer, PET thin layer and second adhesive layer between described insulating barrier, the graphite linings; Be provided with the 3rd adhesive layer between described graphite linings, the absorbed layer; Be provided with the 4th adhesive layer between described absorbed layer, the separated type material layer.
Further improved technical scheme is as follows in the technique scheme:
1, in the such scheme, described PET thin layer thickness is less than 10 microns.
2, in the such scheme, described first adhesive layer, second adhesive layer, the 3rd adhesive layer and the 4th adhesive layer are the esters of acrylic acid adhesive layer.
Because the technique scheme utilization, the utility model compared with prior art has following advantage:
The utility model is used for the pad pasting of electromagnetic wave attenuation, and it comprises insulating barrier, the graphite linings as the reflector, absorbed layer and separated type material layer; Be disposed with first adhesive layer, plastic film layers and second adhesive layer between described insulating barrier, the graphite linings; Be provided with the 3rd adhesive layer between described graphite linings, the absorbed layer; Be provided with the 4th adhesive layer between described absorbed layer, the separated type material layer; Being provided with of reflector can form repeatedly absorption, significantly improved the absorbing property of material; The use of insulating barrier and PET thin layer has improved the intensity of material on the one hand, also increases substantially its proof voltage on the other hand and punctures effect.
