Description
Technical field
This utility model is related to protection of film, is specifically related to a kind of high rigidity oleophobic hydrophobic 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 panoramic protecting film is occurred in that at present, the protecting film of the functional type such as the highest bright protecting film, AG frosted protecting film, mobile phone mirror film, peep-proof film.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; simultaneously when user is on hand with sweat stain or oil stain; touching screen or easy fingerprints or oil stain print; and these impressions are difficult to wiped clean; if it is the most improper to process; can make dirty whole screen; affecting the aesthetic measure of mobile phone, these impressions that simultaneously go down for a long time can slowly corrode screen or screen protecting film.
Additionally, along with the continuous lifting of people oneself's privacy aware, the protection to electronic product privacy information requires the most constantly to promote, but the performance of existing its peep-proof of protecting film is the most poor.
Utility model content
For the deficiencies in the prior art, the purpose of this utility model aims to provide a kind of high rigidity, has the protecting film of oleophobic hydrophobic peep-proof performance.
For achieving the above object, this utility model adopts the following technical scheme that
A kind of high rigidity oleophobic hydrophobic 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 polymethacrylates hardened layer; concave convex texture is distributed on the upper surface of polymethacrylates hardened layer, concave convex texture is fitted with oleophobic hydrophobic 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；Upper surface at described oleophobic hydrophobic layer is fitted with the second poly terephthalic acid class plastics release layer.
The thickness of described OCA glue-line is 20-30 μm.
The thickness of described grating peep-proof layer is 200-300 μm.
Described oleophobic hydrophobic layer is fluorine silicon resin.
The beneficial effects of the utility model are:
High rigidity oleophobic of the present utility model hydrophobic peep-proof protecting film simple in construction, cost of manufacture are low, and have that good hardness, oleophobic be hydrophobic, peep-proof performance.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model high rigidity oleophobic hydrophobic peep-proof protecting film；
In figure: 1, grating peep-proof layer；2, OCA glue-line；3, polymethacrylates hardened layer；4, oleophobic hydrophobic layer；5, layer of silica gel；6, the first poly terephthalic acid class plastics release layer；7, the second poly terephthalic acid class plastics release layer；31, concave convex texture.
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 oleophobic hydrophobic peep-proof protecting film of this utility model preferred embodiment; 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 polymethacrylates hardened layer 3; concave convex texture 31 is distributed on the upper surface of polymethacrylates hardened layer 3, concave convex texture 31 is fitted with oleophobic hydrophobic layer 4；
The most above-mentioned 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, grating peep-proof layer 1 and polymethacrylates hardened layer 3 are bound tightly together, form one, so that whole protecting film has good hardness and peep-proof performance simultaneously；And the polymethacrylates that this polymethacrylates hardened layer 3 uses 188 μ m-thick is base material; it has good flatness; 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 forms hardened layer on the surface of base material; 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；Simultaneously because concave convex texture 31 is distributed on the surface of hardened layer, concave convex texture 31 is beneficial to the laminating with oleophobic hydrophobic layer 4, under the effect of oleophobic hydrophobic layer 4 so that this protecting film can reduce fingerprint and the attachment of various oil stain spot, improves wiped clean ability.Wherein, oleophobic hydrophobic layer 4 uses fluorine silicon resin in this application, and it can form transparent soil resistance epithelium, does not interferes with the outward appearance of product；Wherein, oleophobic hydrophobic layer 4 uses fluorine silicon resin in this application, and it can form transparent soil resistance epithelium, does not interferes with the outward appearance of product.
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 5, the lower surface in layer of silica gel 5 is fitted with the first poly terephthalic acid class plastics release layer 6；Upper surface at oleophobic hydrophobic layer 4 is fitted with the second poly terephthalic acid class plastics release layer 7；When this protecting film is actually used; then need to tear the first poly terephthalic acid class plastics release layer 6 and the second poly terephthalic acid class plastics release layer 7; the side that then this protecting film has layer of silica gel 5 fits on electronic curtain; under the effect of layer of silica gel 5 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 the caking ability between grating peep-proof layer 1 and polymethacrylates hardened layer 3 and the susceptiveness of electrical screen film touch, if the thickness of OCA glue-line 2 is the thinnest, then it is unfavorable for that grating peep-proof layer 1 and polymethacrylates hardened layer 3 form one, 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.
