Abstract
The utility model discloses a PET three-layer scratch-resistant protective film which comprises a PET release film, a PET base material and a PET protective film, wherein the hardened surface of the PET base material is attached to the PET protective film, the non-hardened surface of the PET base material is attached to the PET release film through a rubber layer, the PET protective film comprises a PET protective film base material, a PET protective film rubber layer and a scratch-resistant coating which are attached to one another in sequence, and the scratch-resistant coating is attached to the hardened surface of the PET base material. In this way, the protective film has an automatic adsorbing function and an automatic exhaust function and is capable of eliminating bubbles, low in viscidity, easy to peel off, capable of being stuck repeatedly with using effect not influenced, durable and stable in performance, ultrahigh in light transmittance and surface hardness, good in touching effect, capable of effectively protecting a screen, not prone to injury from hitting or scratching, and not prone to pollution.
Description
Technical field
The utility model relates to protective film of electronic product field, particularly relates to tri-layers of scratch resistant protective film of a kind of PET.
Background technology
Screen protecting film is a kind of transparent medium; main employing PET is former material at present; common screen protecting film only plays the effect of dust protection; the slightly effect that can play anti-scratch of good a bit; be mainly used in all kinds of flat display panels, as the screen protection of mobile phone display screen, electronic navigation read-out, computer display screen and all kinds of touch-screens.
Existing protective film product variety is various, and the main performance assessment criteria of its quality good or not is light transmittance and fastness to rubbing.Existing general protective film penetrability on the market all, below 80%, has had a strong impact on the display effect of screen, and has indirectly reduced the brightness of screen, and long-term use can increase eye fatigue; And PET base material need to be through a high-temperature treatment in carrying out cure process; in high-temperature treatment; due to the inhomogeneous easy generation scattering situation of substrate surface molecular structure; there is rainbow line; more high-intensity cure process, the more difficult control of rainbow line, the existence of rainbow line can affect penetrability and the visual effect of protective film; existing protective film is in order to control rainbow line, and superficial hardness generally can only reach 3.5H left and right.
Utility model content
The technical matters that the utility model mainly solves is: for the deficiencies in the prior art, provide tri-layers of scratch resistant protective film of a kind of PET, have automatic absorbing and automatic ventilating function; can eliminate bubble; and viscosity is low, easily peel off, can repeatedly paste; do not affect result of use; consistency of performance, stable, has superelevation light transmittance and superficial hardness, touches effective; can effectively protect screen, be difficult for damaging, scrape and injure pollution.
For solving the problems of the technologies described above; the technical scheme that the utility model adopts is: tri-layers of scratch resistant protective film of a kind of PET are provided; comprise: PET release film, PET base material and PET protective film; the cure process face of the described PET base material described PET protective film of fitting; the non-cure process face of described PET base material is by glue-line and the laminating of described PET release film; wherein; described PET protective film comprises PET protective film base material, PET protective film glue-line and the anti-scraping coating of laminating successively, and the cure process face of described anti-scraping coating and described PET base material fits.
In preferred embodiment of the utility model, described glue-line is silica gel glue-line.
In preferred embodiment of the utility model, described PET protective film glue-line is acrylic acid glue-line.
In preferred embodiment of the utility model, the thickness of tri-layers of scratch resistant protective film of described PET is 0.08-0.15mm.
In preferred embodiment of the utility model, described PET release film, PET base material and PET protective film base material are light transmittance and reach more than 95% mylar.
In preferred embodiment of the utility model, the superficial hardness of the cure process face of described PET base material reaches 4H.
The beneficial effects of the utility model are: by the PET protective film that contains anti-scraping coating of fitting of the cure process face at PET base material, at non-cure process face laminating PET release film, and PET release film, the light transmittance of PET base material and PET protective film base material all reaches more than 95%, make product there is automatic absorbing and automatic ventilating function, can eliminate bubble, and viscosity is low, easily peel off, can repeatedly paste, do not affect result of use, and consistency of performance, stable, there is superelevation light transmittance and superficial hardness, touch effective, can effectively protect screen, be difficult for damaging, scrape and injure pollution.
