Abstract
The invention discloses a three-layer scratch-resistant PET (polyethylene terephthalate) protective film. The protective film comprises a PET release film, a PET substrate and a PET protective film, wherein the hardening treatment surface of the PET substrate is fit with the PET protective film; the non-hardening treatment surface of the PET substrate is fit with the PET release film via a glue layer; the PET protective film comprises a PET protective film substrate, a PET protective film glue layer and a scratch-resistant coating, which are fit in sequence; and the scratch-resistant coating is fit with the hardening treatment surface of the PET substrate. The protective film has the beneficial effects that the protective film has the functions of automatic adsorption and automatic exhaust, can eliminate bubbles, has low viscosity, is easy to strip, can be repeatedly pasted without affecting the use effect, has durable and stable performances, has ultrahigh light transmittance and surface hardness and a good touch effect, can effectively protect screens and is not easy to bump, scratch and pollute.
Description
Technical field
The present invention relates to the protective film of electronic product field, particularly relate to three layers of scratch resistant diaphragm 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 display screen, computer display screen and all kinds of touch-screens.
Existing diaphragm product variety is various, and the main performance assessment criteria of its quality good or not is light transmittance and abrasion resistance.Have general on the market diaphragm light transmittance now all below 80%, had a strong impact on the display effect of screen, and indirectly reduced the brightness of screen, the long-term use can increase eye fatigue; And the PET base material need to be through a high-temperature process when carrying out cure process; in high-temperature process; due to the inhomogeneous easy generation scattering situation of substrate surface molecular structure; the rainbow line appears; more high-intensity cure process, the more difficult control of rainbow line, the existence of rainbow line can affect light transmittance and the visual effect of diaphragm; existing diaphragm is in order to control the rainbow line, and case hardness generally can only reach the 3.5H left and right.
Summary of the invention
The technical problem that the present invention mainly solves is: for the deficiencies in the prior art, provide three layers of scratch resistant diaphragm of a kind of PET, have automatic absorbing and automatic ventilating function; can eliminate bubble; and viscosity is low, easily peels off, and can repeatedly paste; do not affect result of use; consistency of performance, stable has superelevation light transmittance and case 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 present invention adopts is: three layers of scratch resistant diaphragm of a kind of PET are provided; comprise: PET mould release membrance, PET base material and PET diaphragm; the described PET diaphragm of cure process face applying of described PET base material; the non-cure process face of described PET base material is fitted by glue-line and described PET mould release membrance; wherein; described PET diaphragm comprises PET diaphragm base material, PET diaphragm glue-line and the anti-scraping coating of fitting successively, and the cure process face of described anti-scraping coating and described PET base material fits.
In a preferred embodiment of the present invention, described glue-line is the silica gel glue-line.
In a preferred embodiment of the present invention, described PET diaphragm glue-line is the acrylic acid glue-line.
In a preferred embodiment of the present invention, the thickness of three layers of scratch resistant diaphragm of described PET is 0.08-0.15mm.
In a preferred embodiment of the present invention, described PET mould release membrance, PET base material and PET diaphragm base material are light transmittance and reach polyester film more than 95%.
In a preferred embodiment of the present invention, the case hardness of the cure process face of described PET base material reaches 4H.
The invention has the beneficial effects as follows: contain the PET diaphragm of anti-scraping coating by fitting at the cure process face of PET base material; at non-cure process face applying PET mould release membrance; and the light transmittance of PET mould release membrance, PET base material and PET diaphragm base material all reaches more than 95%; make product have automatic absorbing and automatic ventilating function; can eliminate bubble; and viscosity is low; easily peel off; can repeatedly paste, not affect result of use, and consistency of performance, stable; have superelevation light transmittance and case hardness; touch effectively, can effectively protect screen, be difficult for damaging, scrape and injure pollution.
Description of drawings
Fig. 1 is the structural representation of three layers of scratch resistant diaphragm one preferred embodiment of PET of the present invention;
In accompanying drawing, the mark of each parts is as follows: 1, PET mould release membrance, 2, glue-line, 3, the PET base material, 4, the PET diaphragm, 41, PET diaphragm base material, 42, PET diaphragm glue-line, 43, anti-scraping coating.
The specific embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made more explicit defining.
See also shown in Figure 1ly, the embodiment of the present invention comprises:
Three layers of scratch resistant diaphragm of a kind of PET; comprise: PET mould release membrance 1, PET base material 3 and PET diaphragm 4; the described PET diaphragm 4 of cure process face applying of described PET base material 3; the non-cure process face of described PET base material 3 is fitted by glue-line 2 and described PET mould release membrance 1; wherein; described PET diaphragm 4 comprises PET diaphragm base material 41, PET diaphragm glue-line 42 and the anti-scraping coating 43 of fitting successively, and described anti-scraping coating 43 fits with the cure process face of described PET base material 3.
Wherein, described glue-line 2 is the silica gel glue-line, and smooth surface is had automatic absorbing and automatic ventilating function, can eliminate bubble, and viscosity is low, easily peels off, and can repeatedly paste, and does not affect result of use, and good confining force is arranged under hot environment.
Described PET diaphragm glue-line 42 is the acrylic acid glue-line, has the characteristics such as heat-resisting, ageing-resistant performance, oil resistant, uvioresistant, and consistency of performance, stable.
