At present, microminiaturized, Highgrade integration is the main trend of electronic product development, and the inner space of these products is relatively narrow and small.In absorbing material, patch-type absorbing material thickness is thin, easy to use, for reduction electromagnetic radiation, prevents electromagnetic interference from having good effect, is relatively applicable to being applied in electronic product.Therefore, the patch-type electromagnetic wave absorbent material design and develop that thickness is thin, quality is light, being applicable to small space, becomes the direction that those skilled in the art make great efforts.
Summary of the invention
The utility model provides a kind of suction ripple film for communication product, and this suction ripple film for communication product improves the utilance of metal layer reflection electromagnetic field, and arranging of metal level can form re-absorption effect, significantly improves the absorbing property inhaling ripple film.
For achieving the above object, the technical solution adopted in the utility model is: a kind of suction ripple film for communication product, comprises PET insulating barrier, metal level, suction ripple layer and separated type material layer; The first adhesive layer is provided with between PET insulating barrier and metal level, the second adhesive layer is provided with between described metal level and suction ripple layer, be provided with the 3rd adhesive layer between described suction ripple layer and separated type material layer, the surface that described metal level contacts with suction ripple layer is provided with several prismatic protrusions portions arranged in parallel.
The technical scheme improved further in technique scheme is as follows:
1, in such scheme, described PET thickness of insulating layer is less than 10 microns.
2, in such scheme, described first adhesive layer, the second adhesive layer and the 3rd adhesive layer are esters of acrylic acid adhesive layer.
3, in such scheme, the thickness of described first adhesive layer is less than the thickness of the second adhesive layer, and the thickness of described second adhesive layer is less than the 3rd adhesive layer.
Because technique scheme is used, the utility model compared with prior art has following advantages:
The utility model is used for the suction ripple film of communication product, and which raises the utilance of metal layer reflection electromagnetic field, arranging of metal level can form re-absorption effect, significantly improves the absorbing property inhaling ripple film; The use of insulating barrier and PET film layer improves the intensity of material on the one hand, has also increased substantially the effect that its proof voltage punctures on the other hand.
