Summary of the invention
The utility model provides a kind of screened film for electronic product, and this screened film for electronic 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 of screened film; And the discharge of gas when being conducive to fitting, thus avoid the generation of bubble.
For achieving the above object, the technical solution adopted in the utility model is: a kind of screened film for electronic 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 surface that described 3rd adhesive layer contacts with separated type material layer has several salient points.
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 average height of described salient point is 3. 8 microns ~ 10 microns.
Because technique scheme is used, the utility model compared with prior art has following advantages:
The utility model is used for the screened film of electronic 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 of screened 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; Secondly, the surface that its 3rd adhesive layer contacts with separated type material layer has several salient points, the discharge of gas when being conducive to fitting, thus avoids the generation of bubble.
