The arbitrary and all combination of project.
For example, a kind of transparent release film, including PET transparent film layers, the first moth eye film layer, the second moth eye film layer and release
Layer, the first moth eye film layer are fitted on the PET transparent film layers, and it is transparent that the second moth eye film layer fits in the PET
On side of the film layer away from the first moth eye film layer, the release layer fits in the second moth eye film layer away from the PET
The side of transparent film layer, a side of the PET transparent film layers are provided with extension, and the extension has turnover corner structure.
In order to further illustrate above-mentioned transparent release film, another example is, referring to Fig. 1, transparent release film 10 includes
PET transparent film layers 100, the first moth eye film layer 200, the second moth eye film layer 300 and release layer 400, the first moth eye film layer
200 fit on the PET transparent film layers 100, and it is separate that the second moth eye film layer 300 fits in the PET transparent film layers 100
On the side of the first moth eye film layer 200, the release layer 400 fits in the second moth eye film layer 300 away from the PET
The side of transparent film layer 100.Variation of the moth eye film by virtually eliminating the refractive index at interface eliminates light to make light transmission
Reflection, in this way, by setting the first moth eye film layer and the second moth eye film layer in the both sides of PET transparent film layers, based on the first moth eye
In film layer and the second moth eye film layer there is the nanostructured of antireflection, the reflective of PET hyaline membranes can be reduced, so as to solve
" the existing transparent release films of PET are susceptible to the problem of reflective so that some more demanding application field applications are limited "
Problem so that above-mentioned transparent release film can reduce the transparent release films of PET and reflective problem occurs, and application field is wider.
It should be noted that moth eye film is already belonging to the prior art, the structural principle of bionics " moth eye " has mainly been used,
Referred to as " moth eye effect ", when material surface submicron structure scale is less than optical wavelength, it is micro- will so that light wave is beyond recognition out this
Structure, then material surface refractive index along depth direction in consecutive variations, caused by can reducing refractive index change dramatically
Reflex, the moth eye film have transparent configuration.
It please refers to Fig.1 and Fig. 2, a side of the PET transparent film layers 100 is provided with extension 110, the extension
110 have turnover corner structure 111.For another example, the PET transparent film layers have opposite two sides, wherein described in a side setting
Extension, for another example, the side of the PET transparent film layers refer to the side not being bonded with the first moth eye film layer, also not
The side being bonded with the second moth eye film layer.In this way, by being provided with extension in a side of the PET transparent film layers,
And the extension has turnover corner structure, can be convenient for tearing off above-mentioned transparent release film.For another example, the deflection angle knot
The deflection angle number of degrees of structure are 60 degree~100 degree.For another example, the deflection angle number of degrees of the turnover corner structure are 80 degree~95 degree.In this way,
It can be further convenient for user by being torn off from the extension by above-mentioned transparent release film.For another example, the deflection angle knot
The deflection angle number of degrees of structure are 90 degree.In this way, user is also convenient for during use carries out alignment operation to the transparent release film, just
In to the transparent release film progress pad pasting.
In order to obtain preferable reflecting effect, in an embodiment, the thickness of the second moth eye film layer is 80 microns~90
Micron.For another example, the thickness of the first moth eye film layer is 70 microns~80 microns.It so, it is possible to obtain preferable reflecting effect.
For another example, the thickness ratio of the PET transparent film layers, the first moth eye film layer, the second moth eye film layer and release layer is 1：(0.6~
0.8)：(0.7~0.9)：(0.4~0.8).For another example, the PET transparent film layers, the first moth eye film layer, the second moth eye film layer and
The thickness ratio of release layer is 1：(0.72~0.76)：(0.8~0.85)：(0.45~0.55).For another example, the PET transparent film layers,
The thickness ratio of first moth eye film layer, the second moth eye film layer and release layer is 1：0.75：0.84：0.54.So, it is possible obtain compared with
Good reflecting effect, and thickness is moderate, based on the nanostructured in the first moth eye film layer and the second moth eye film layer with antireflection,
The reflective of PET hyaline membranes can be reduced, so as to solve the problems, such as that " the existing transparent release films of PET are susceptible to reflective, make
It is limited to obtain some more demanding application fields applications " the problem of so that it is transparent release that above-mentioned transparent release film can reduce PET
There is reflective problem in film, and application field is wider.
In order to make the PET transparent film layers high temperature resistant, in an embodiment, the PET transparent film layers and second moth eye
Water white transparency fire resistant polyimide nano compound film layer is additionally provided between film layer, the water white transparency high temperature resistant polyamides is sub-
Amine nano compound film layer is bonded the side of the PET transparent film layers away from the first moth eye film layer, second moth eye film
Layer is bonded the side of the water white transparency fire resistant polyimide nano compound film layer away from the PET transparent film layers.It is colourless
Transparent high temperature resistant polyimide nano composite thin film layer has preferable heat-resisting ability and heat-insulating capability, water white transparency high temperature resistant
Polyimide nano composite thin film layer still has preferable stability at 260 degrees Celsius, and light transmittance is more than 90%, compared with
Good heat-insulating capability can reduce heat and conduct to PET transparent film layers, can make transparent release film be suitable for 150 degrees Celsius~
200 degrees Celsius of hot environment, application field are wider.It should be further noted that water white transparency fire resistant polyimide is received
Rice composite film layer is known materials, is possessed preferable using water white transparency fire resistant polyimide nano compound film
Heat resistance and mechanical performance.It is prepared for example, referring to CN105440284A.For another example, by being ground to Beijing aeronautical material
Study carefully institute to buy.
Above-mentioned transparent release film, by setting the first moth eye film layer and the second moth eye film layer in the both sides of PET transparent film layers,
Based on the nanostructured in the first moth eye film layer and the second moth eye film layer with antireflection, the reflective of PET hyaline membranes can be reduced,
So as to solve the problems, such as that " the existing transparent release films of PET are susceptible to reflective so that some more demanding application fields
