Abstract
The utility model relates to a transparent electromagnetic wave screening film for use in a mobile phone, aiming to solve the electromagnetic radiation of the mobile phone. The utility model adopts a technical proposal that the transparent electromagnetic wave screening film comprises a transparent support body 1 and a metal conducting layer 2 arranged on one side of the transparent support body 1. The screening film provided by the utility model, which can be attached on a surface or a back of a mobile phone screen, has the advantages of effectively reducing the intensity of electromagnetic radiation of the mobile phone, protecting the health of the owner of mobile phone, and can be correspondingly cut according to the sizes of mobile phone screens so as to attach on the surface of the mobile screens.
Description
Technical field
The utility model relates to a kind of screened film, the electromagnetic shielding film that uses on particularly a kind of mobile phone.
Background technology
Along with the develop rapidly of telecommunication technology, use the people of mobile phone more and more.Mobile phone intensity of its emission radio-frequency carrier power in use is far longer than requirement to the human body firm power.Behind the long-term use mobile phone, the electromagnetic radiation of its generation is easy to cause symptoms such as people have a headache, dizziness, insomnia, dreaminess, human body also has very strong excitement, this is a kind of electromagnetic radiation pollution, therefore, the associated health problems of being brought by mobile phone has caused showing great attention to of people, and the electromagnetic radiation of mobile phone can not be ignored.
Summary of the invention
The utility model be used to overcome above-mentioned prior art defective, provide a kind of and do not influence function of use, shield effectiveness height, can effectively play the mobile phone that prevents electromagnetic radiation transparent electromagnetic wave screened film.
For solving the problems of the technologies described above, the technical scheme that the utility model is taked is:
A kind of mobile phone transparent electromagnetic wave screened film comprises transparent support 1 and at its metal conducting layer that simultaneously is provided with 2 in the formation.
Above-mentioned mobile phone transparent electromagnetic wave screened film, the another side of described transparent support 1 are provided with adhesive layer 3 and peel ply 5, and metal conducting layer 2 is provided with hard conating 4.
Above-mentioned mobile phone transparent electromagnetic wave screened film, the another side of described transparent support 1 is provided with hard conating 4, and metal conducting layer 2 is provided with adhesive layer 3 and peel ply 5.
Above-mentioned mobile phone transparent electromagnetic wave screened film, described transparent support 1 are PETG (PET) film.
Above-mentioned mobile phone transparent electromagnetic wave screened film, described metal conducting layer 2 is the aperture plate shape.
The transparent support that uses in the utility model, can be by pet resin, diacetate resin, triacetate resin, polyethylene, polypropylene, polystyrene, Corvic, polyketone ether, the single or multiple lift film that polysulfones, polyether sulfone, Merlon, polyamide, acrylic resin, Triafol T etc. constitute.Take all factors into consideration from aspects such as light transmission, thermal endurance and prices, first-selected base material is PETG (PET) film.
It is that 200610102252.0 Chinese patent (name is called a kind of electromagnetic shielding film and manufacture method thereof) disclosed method obtains that metal conducting layer can adopt application number.
In order to improve resistance to wear and the scratch resistance intensity of mobile phone with transparent screened film, the utility model scribbles hard conating on the another side of transparent support or metal conducting layer, its can adopt dip-coating, extruding to be coated with, to slide coating, curtain are coated with, known coating methods such as rod is coated with, air knife coating, roller coat, heliogravure coating, spraying are coated with and obtain.Coating should be evenly, continuous coating.
For the transparent electromagnetic wave screened film that the utility model is provided plays the effect that prevents electromagnetic radiation in the use of mobile phone, it need be sticked on the mobile phone screen surfaces or the back side, therefore, be provided with adhesive layer on the another side of the transparent electromagnetic wave screened film support that the utility model provides or metal conducting layer, adhesive layer is by forming behind pressure-sensitive adhesive coating or the silica gel.
Adhesive layer can adopt and earlier adhesive is coated on the transparent support that has screened film, and is compound with peel ply then; Also can earlier adhesive be coated on the peel ply, compound with the transparent support that has screened film then, compoundly can adopt general roll extrusion mode.
To prevent electromagnetic radiation in order playing, to stick on the mobile phone screen surfaces after only peel ply need being peeled off or the back side gets final product, do not need mobile phone is carried out machinery or circuit modification, easy to use, attractive in appearance.
The utility model does not influence speech quality on function, and can effectively weaken the electromagnetic wave radiant intensity that mobile phone produces, and reduces the harm of electromagenetic wave radiation to human body, the protection health; Structurally, take form of film, easy to use, attractive in appearance; In addition, can also reduce the friction of mobile phone screen surfaces, avoid wearing and tearing.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2,3 is respectively the structural representation that has hard conating, adhesive layer and peel ply.
Each label list is shown among the figure: 1. transparent support; 2. metal conducting layer; 3. adhesive layer; 4. hard conating; 5. peel ply.
Embodiment
The utility model is described in further detail below by specific embodiment.
Form the metal grid mesh conductive layer on transparent support earlier, its formation method can adopt the method for patent disclosure mentioned above.
Coating contains the hard coating solution of esters of acrylic acid prepolymer on the metal grid mesh conductive layer, through 80 ℃ of dryings 4～5 minutes, solidifies 40 seconds under uviol lamp then, obtains hard conating.
At the another side of transparent support coating pressure-sensitive acrylate adhesive, through 110 ℃ of dryings 5～6 minutes, the stripping film that scribbles siliceous release layer then in advance was compound, obtained in the utility model the mobile phone of structure transparent electromagnetic wave screened film as shown in Figure 2.
The hard coating solution that also can contain the esters of acrylic acid prepolymer in the coating of the another side of transparent support through 60 ℃ of dryings 2～3 minutes, solidified 60 seconds under uviol lamp then, can obtain having the electromagnetic shielding film of hard conating.
On the siliceous release layer of stripping film, be coated with pressure-sensitive acrylate adhesive, metal grid mesh conductive layer through 120 ℃ of dryings pre-band hard conating electromagnetic shielding film after 3～4 minutes is compound, rolling obtains in the utility model the electromagnetic shielding film of structure as shown in Figure 3.
