Description
Technical field
This utility model is related to protection of film, is specifically related to a kind of high rigidity peep-proof protecting film.
Background technology
Along with the development of information-based industry, the use of geo-informatization system is also got more and more by people, and protecting film is widely used on the display screen of various electronic product, to protect display screen.The most also occur in that panoramic protecting film at present, but function is the most single, it is difficult to meet actual use requirement.
Display screen usually can be due to fingernail or other hard things continuous paddling on a display screen during using; thus certain scratch or abrasion can be caused in screen surface; and then the normal using effect of product can be affected, therefore people habitually can stick protecting film to protect display screen on the screen of electronic product.
But generally there is the defects such as low, the peep-proof poor performance of hardness in current protecting film, the service life thus making protecting film is short, is unfavorable for the secret protection of electronic product user.
Utility model content
For the deficiencies in the prior art, the purpose of this utility model aims to provide a kind of hardness height and has the protecting film of peep-proof function.
For achieving the above object, this utility model adopts the following technical scheme that
A kind of high rigidity peep-proof protecting film; including grating peep-proof layer; upper surface at grating peep-proof layer is fitted with OCA glue-line; upper surface at OCA glue-line is fitted with without Newton's ring poly terephthalic acid class plastic hardening layer, grating peep-proof layer, OCA glue-line and form one without Newton's ring poly terephthalic acid class plastic hardening layer；This grating peep-proof layer uses poly terephthalic acid class plastics to be base material, polarizing angle≤25 °, mist degree≤10 °.
Lower surface at described grating peep-proof layer is fitted with layer of silica gel, and the lower surface in layer of silica gel is fitted with the first poly terephthalic acid class plastics release layer；It is fitted with the second poly terephthalic acid class plastics release layer at the upper surface without Newton's ring poly terephthalic acid class plastic hardening layer.
The thickness of described OCA glue-line is 20-30 μm.
The thickness of described grating peep-proof layer is 200-300 μm.
The beneficial effects of the utility model are:
High rigidity peep-proof protecting film of the present utility model mainly forms by grating peep-proof layer, OCA glue-line and without Newton's ring poly terephthalic acid class plastic hardening layer, and simple in construction, cost of manufacture are low, and the hardness having and peep-proof performance.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model high rigidity peep-proof protecting film；
In figure: 1, grating peep-proof layer；2, OCA glue-line；3, without Newton's ring poly terephthalic acid class plastic hardening layer；4, layer of silica gel；5, the first poly terephthalic acid class plastics release layer；6, the second poly terephthalic acid class plastics release layer.
Detailed description of the invention
Below, in conjunction with accompanying drawing and detailed description of the invention, this utility model is described further:
As shown in Figure 1; structural representation for the high rigidity peep-proof protecting film of this utility model preferred embodiment example; including grating peep-proof layer 1; upper surface at grating peep-proof layer 1 is fitted with OCA glue-line 2; upper surface at OCA glue-line 2 is fitted with without Newton's ring poly terephthalic acid class plastic hardening layer 3, grating peep-proof layer 1, OCA glue-line 2 and form one without Newton's ring poly terephthalic acid class plastic hardening layer 3；This grating peep-proof layer 1 uses poly terephthalic acid class plastics to be base material, polarizing angle≤25 °, mist degree≤10 °.
High rigidity peep-proof protecting film the most of the present utility model is mainly constituted by grating peep-proof layer 1, OCA glue-line 2 and without Newton's ring poly terephthalic acid class plastic hardening layer 3；Wherein this grating peep-proof layer 1 mainly uses poly terephthalic acid class plastics to be base material; and use grating polarization light technology that it is processed; make its polarizing angle≤25 °; mist degree≤10 °; so that the polarizing angle of this grating peep-proof layer 1 can realize 180 ° of light weakens refraction, this protecting film is covered on electronic curtain, during normal use; refraction light in the left and right sides can increase along with the elevation angle more than 25 ° of visual angles and gradually weaken, thus reaches the peep-proof effect in using；
Meanwhile, under the effect of OCA glue-line 2, it is bound tightly together by grating peep-proof layer 1 with without Newton's ring poly terephthalic acid class plastic hardening layer 3, forms one, so that whole protecting film has good hardness and peep-proof performance simultaneously；And these class plastics of poly terephthalic acid without Newton's ring using 188 μ m-thick without Newton's ring poly terephthalic acid class plastic hardening layer 3 are base material, and the surface of base material is carried out sided corona treatment, to remove the inertia of base material, then the surface-coated at base material has hardening bath (being mainly made up of) Silicon stone and polyethylene, after photocuring, thus on the surface of base material, form hardened layer, the thickness of this hardened layer is about 30 μm, so that protecting film has the hardness of 9H and ensures the touch-sensitive of protecting film, and this hardened layer possesses good structural deformation recovery function, it is specially under 500g pressure, uses the pyrite brush obvious cut that wiper causes back and forth on the surface of hardened layer, can be rebounded in 2 seconds reply voluntarily.
It addition, for the surface protecting this protecting film, the lower surface at above-mentioned grating peep-proof layer 1 is fitted with layer of silica gel 4, the lower surface in layer of silica gel 4 is fitted with the first poly terephthalic acid class plastics release layer 5；It is fitted with the second poly terephthalic acid class plastics release layer 6 at the upper surface without Newton's ring poly terephthalic acid class plastic hardening layer 3；When this protecting film is actually used; then need to tear the first poly terephthalic acid class plastics release layer 5 and the second poly terephthalic acid class plastics release layer 6; the side that then this protecting film has layer of silica gel 4 fits on electronic curtain; under the effect of layer of silica gel 4 such that it is able to quickly and efficiently this protecting film is fitted on electrical screen film.
Wherein, the thickness of OCA glue-line 2 can affect grating peep-proof layer 1 and the susceptiveness touched without the caking ability between Newton's ring poly terephthalic acid class plastic hardening layer 3 and electrical screen film, if the thickness of OCA glue-line 2 is the thinnest, then it is unfavorable for grating peep-proof layer 1 and forms one without Newton's ring poly terephthalic acid class plastic hardening layer 3, otherwise, the thickness of OCA glue-line 2 cross thin if, then it is unfavorable for the susceptiveness that electrical screen film touches, numerous studies through inventor find, when the thickness of above-mentioned OCA glue-line 2 is 20-30 μm, can preferably balance relation between the two, and it is preferably 25 μm in the present embodiment.
Wherein, the research through inventor finds, when the thickness of above-mentioned grating peep-proof layer 1 is 200-300 μm, does not only interfere with the susceptiveness that electrical screen film touches, and so that protecting film has preferably peep-proof performance.
It will be apparent to those skilled in the art that can technical scheme as described above and design, make other various corresponding changes and deformation, and within all these changes and deformation all should belong to this utility model scope of the claims.
