Abstract
The utility model relates to a novel protective film. The novel protective film comprises a PET (polyethylene terephthalate) film, toughened glass, a PET anti-explosion film and a PET stripping film, wherein the PET film is attached on the upper surface of the toughened glass by an adhesive, the upper surface of the PET anti-explosion film is attached on the lower surface of the toughened glass by the adhesive, and the PET stripping film is attached on the lower surface of the PET anti-explosion film by the adhesive. The touch screen protective film is easy to bond, the bonded surface can be cleaned easily, the flying off phenomenon can be effectively prevented, no air bubbles are formed, no watermark is caused, and the scratching phenomenon is avoided.
Description
Technical field
The utility model relates to screen of mobile terminal screen protection membrane technology, more particularly, relates to a kind of new Type Protecting Film.
Background technology
Along with the development of information age, electronic product has incorporated our life, becomes our the indispensable part of living.Touch screen has been widely used in the mobile terminals such as electronic product mobile phone, and the protectiveness product of touch screen is a lot, the existing diaphragm product adopting, and case hardness deficiency, is easily drawn and is scraped, and leaves cut; Although some diaphragm product hardness is enough, does not possess explosion prevention function and affect the value of screen itself.A kind of new Type Protecting Film is now proposed, can anti-surface scratches, pasting also not can bubble, also there will not be the problems such as glass decorative pattern, watermark after stickup.
Utility model content
The technical problem that the utility model solves is to provide a kind of new Type Protecting Film, to solve the shortcoming in above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions:
A kind of new Type Protecting Film, comprises PET film, safety glass, PET rupture pressure disc, PET stripping film; Described PET film by adhesive attachment at safety glass upper surface; The upper surface of described PET rupture pressure disc by adhesive attachment at safety glass lower surface; Described PET stripping film is the lower surface at PET rupture pressure disc by adhesive attachment.
Further, described PET film, PET rupture pressure disc, PET stripping film optimum thickness are 50u;
Further, described safety glass optimum thickness range is 0.2-0.42mm;
Described safety glass case hardness reaches 5-8H, and the maximum dynamics of bearing is 4KG, and surfaces A S processes, and thickness of glass is that 0.4MM and light transmittance reach 95% ~ 99%, promotes 2.5D arc limit technology on prior art point, and stereoeffect is remarkable.
Described PET rupture pressure disc internal layer adopts one deck breathable material, after pasting with the touch screen of mobile phone or other-end product, there will not be bubble and glass decorative pattern, and when cracked, glass also can not disperse, and has improved the security of product.
beneficial effect
Touch screen diaphragm of the present utility model is easily pasted, and easily effects on surface cleans, can effectively prevent from dispersing, and without bubble, no-watermark, anti-scratch.
Accompanying drawing explanation
Fig. 1 is a kind of new Type Protecting Film structural representation.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, a kind of new Type Protecting Film, comprises PET film 1, safety glass 2, PET rupture pressure disc 3, PET stripping film 4; Described PET film 1 by adhesive attachment at safety glass 2 upper surfaces; The upper surface of described PET rupture pressure disc 3 by adhesive attachment at safety glass 2 lower surfaces; Described PET stripping film 4 is the lower surface at PET rupture pressure disc 3 by adhesive attachment.
Described safety glass 2 case hardnesses reach 5-8H, and the minimum dynamics of bearing is 4KG, and surfaces A S processes, and thickness of glass is that 0.4MM and light transmittance reach 95% ~ 99%, promotes 2.5D arc limit technology on prior art point, and stereoeffect is remarkable.
Described PET rupture pressure disc 3 internal layers adopt one deck breathable material, after pasting with the touch screen of mobile phone or other-end product, there will not be bubble and glass decorative pattern, and when cracked, glass also can not disperse, and has improved the security of product.
A kind of new Type Protecting Film that the utility model provides, adopts roll extrusion technology that PET rupture pressure disc is bonded at by force on safety glass, solves Bubble formation through vacuum defoamation technique simultaneously.
The utility model has been carried out to various tests, and test result is as follows.
1) shock-testing
In the vertical drop of 1 meter of height, this product is not caused to any damage with Metal Ball, knock this product with iron hammer gravity; as cracked as spider pearl net; but mobile phone surface is intact, knock in the same manner the series products that attaches general diaphragm, cannot safeguard protection mobile phone liquid-crystalline glasses.
2) surperficial scratch test
Use cutter directly arbitrarily to portray on safety glass surface, can not cause scar by his-and-hers watches, in an identical manner, reach the like products such as protection PET/PMMA/CP of 9H-10H in case hardness, still can leave scar.
3) surface abrasion test
Use the directly mill picture arbitrarily on cover glass film surface of electric drill, can not cause scar to this product, in an identical manner, reach the like products such as protection PET/PMMA/CP of 9H-10H in case hardness, still can leave scar.
4) optical characteristics
Light transmittance reaches 95% ~ 99% image quality, better than liquid crystal protective film image quality.
5) waterproof and anti-fingerprint characteristic
Adopt AS and AF to process, allow safety glass surface there is waterproof and anti-fingerprint effect.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model, the technical staff of the industry should understand, the utility model is not restricted to the described embodiments, that in above-described embodiment and description, describes just illustrates principle of the present utility model, do not departing under the prerequisite of the utility model spirit and scope, the utility model also has various changes and modifications, these changes and improvements all fall within the scope of claimed the utility model, the claimed scope of the utility model is defined by appending claims and equivalent thereof.
