Description
Technical field
The utility model belongs to technical field of electronic materials, particularly relates to a kind of shielding pad pasting.
Background technology
At present, as shielding material widely used metal sheet or net heavier, have in the housing of the equipment of being configured in and need cost labour and the problem of time.And there is electro-magnetic wave absorption ability and there is large anisotropic tendency in the sheet of metal or net, the tendency that namely electro-magnetic wave absorption ability significantly declines when electromagnetic incidence angle increases.The electromagnetic wave that electronic product discharges, brings electromagnetic interference can to other electronic equipment of surrounding, make its operation irregularity; Also can work the mischief to health simultaneously.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 shielding pad pasting, and this shielding pad pasting improves the utilance of metal layer reflection electromagnetic field, and arranging of metal level can form re-absorption effect, significantly improves the absorbing property of material.
For achieving the above object, the technical solution adopted in the utility model is: a kind of shielding pad pasting, 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, the 3rd adhesive layer is provided with between described suction ripple layer and separated type material layer, described metal level with inhale the surface that ripple layer contacts and be provided with several prismatic protrusions portions arranged in parallel, described PET insulating barrier and the opposing plated surface of the first adhesive layer are covered with metallic silver layer.
The technical scheme improved further in technique scheme is as follows:
1, 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.
2, in such scheme, described PET thickness of insulating layer is 40 ~ 80 microns.
Because technique scheme is used, the utility model compared with prior art has following advantages:
The utility model shielding pad pasting, which raises the utilance of metal layer reflection electromagnetic field, arranging of metal level can form re-absorption effect, significantly improves the absorbing property of material; The use of insulating barrier and PET film layer improves the intensity of material on the one hand; Secondly, its PET insulating barrier plated surface opposing with the first adhesive layer is covered with metallic silver layer, and metal level, between metallic silver layer and suction ripple layer, further increases the absorbing property that improve material.
