Description
Technical field
The utility model is related to protective film fields, and in particular to a kind of peep-proof TPU protective films.
Background technology
With the development of information age, mobile phone becomes the carrier that information exchange is transmitted, and people are to the hidden of electronic product
Private protection requires also to be continuously improved.Currently, protective film product as information protection is mainly based on peep-proof PET composite material,
But with the development of curve screens, PET composite material is difficult to adapt to big radian screen.Current protective film pastes on the screen
When, the laminating degree of the marginal position and radian screen of surrounding is poor so that the arcuate positions of screen edge cannot be protected, simultaneously
Also the beauty of screen is influenced.
Utility model content
In view of the deficiencies of the prior art, it the purpose of the utility model is to provide a kind of peep-proof TPU protective films, can be bonded big
Radian screen, while there is peep-proof performance, improve protective film fitness.
To achieve the above object, the utility model adopts the following technical solution：
A kind of peep-proof TPU protective films include the second release layer successively from top to bottom, surface-treated layer, TPU base materials, prevent
Peep layer and the first release layer, between the TPU base materials and peep-proof layer by optics OCA layers be bonded, the table of the peep-proof layer
Face is provided with concave convex texture, and black resin filler, the peep-proof layer and the first release layer are filled between concave convex texture gap
Between be coated with glue-line.
Further, second release layer is set as poly terephthalic acid class plastic layer, and thickness is 25~100um.
Further, the surface-treated layer is set as smooth layer, and thickness is 10~20um.
Further, the surface-treated layer is set as frosted layer, and thickness is 3~8um.
Further, the thickness of the TPU base materials is set as 50~200um.
Further, optics OCA layers of the thickness is set as 25~150um.
Further, the polarizing angle of the peep-proof layer is less than or equal to 25 °, and mist degree is less than or equal to 10 °.
Further, re-coating has the second peep-proof layer, the second peep-proof layer surface lines and peep-proof layer surface on peep-proof layer
Lines is in 90 °.
Further, the glue-line is set as acrylic glue or silica gel, bondline thickness 25-125um.
Further, first release layer is set as poly terephthalic acid class plastic layer, and thickness is 25~100um.
The beneficial effects of the utility model are：
TPU base materials are more soft, and glue-line has certain viscosity, is substantially increased when being in direct contact screen and big radian
The compactness of screen, while peep-proof layer is added, energy effective protection individual privacy enhances the protecting effect to screen.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Reference numeral：1, the second release layer；2, surface-treated layer；3, TPU base materials；4, optics OCA layers；5, peep-proof layer；6、
Glue-line；7, the first release layer.
Specific implementation mode
In the following, in conjunction with attached drawing and specific implementation mode, the utility model is described further：
As shown in Figure 1, a kind of peep-proof TPU protective films, include the second release layer 1, surface-treated layer successively from top to bottom
2, TPU base materials 3, peep-proof layer 5 and the first release layer 7, second release layer 1 are set as poly terephthalic acid class plastic layer,
Thickness is 25~100um, is protection materials use from polluting or scratching.
The surface-treated layer 2 can be coated with by net roll, scraper type is coated with and the modes such as spraying method are to TPU base materials 3
Surface is handled, wherein the surface-treated layer 2 may be configured as smooth layer, i.e., carries out smooth treatment to TPU base materials 3, thick
Degree is 10~20um；The surface-treated layer 2 is also configured as frosted layer, i.e., carries out frosted processing, thickness 3 to TPU base materials 3
~8um.
The TPU base materials 3 are made of optical grade Thermoplastic polyurethane elastomer material, and TPU base materials 3 have preferable soft
Property so that protective film is set as 50~200um with that can be bonded the screen with radian, the thickness of the TPU base materials 3.
It is bonded by optics OCA layers 4 between the TPU base materials 3 and peep-proof layer 5, optics OCA layers 4 are optical cement, tool
Have the characteristics that water white transparency, light transmission rate are high, the thickness of the optics OCA layers 4 is set as 25~150um.
The peep-proof layer 5 is handled it using ultra-fine shutter optical technology, the first stage using UV be coated with or
Hot press printing technology is provided with concave convex texture on the surface of peep-proof film, and second stage is in practical wet coating technology between concave convex texture
Black resin filler is filled between gap, the polarizing angle of the peep-proof layer 5 is less than or equal to 25 °, and mist degree is less than or equal to 10 °,
So that polarizing angle can realize that 180 ° of light weaken refraction, during normal use, it is more than 25 ° that the left and right sides, which reflects light,
Visual angle can gradually be weakened as the elevation angle increases, to reach the peep-proof effect in use.
And re-coating has the second peep-proof layer 5,5 surface pattern of the second peep-proof layer and 5 surface pattern of peep-proof layer on peep-proof layer 5
In 90 °, you can reach 360 ° of peep-proof effects.
Glue-line 6 is coated between 5 and first release layer 7 of the peep-proof layer, the glue-line 6 is set as acrylic glue or silicon
Glue, 6 thickness of glue-line are 25-125um.Glue-line 6 has certain viscosity, after tearing up the first release layer 7, glue-line 6 and screen
It is in direct contact, in addition the flexibility of TPU base materials 3, can be such that protective film is covered on the screen with big radian, improves the patch of protective film
Conjunction degree.
First release layer 7 is set as poly terephthalic acid class plastic layer, and thickness is 25~100um, is to protect
Glue-line 6 influences to use from pollution.
It will be apparent to those skilled in the art that technical solution that can be as described above and design, make various other
Corresponding change and deformation, and all these changes and deformation should all belong to the protection of the utility model claims
Within the scope of.
