As shown in figure 1, the diaphragm provided in an embodiment of the present invention for cover plate, including transparent base 10, ink layer 20, UV
Texture layer 30, optical film 40, transparent base 10 include the relative second surface 10b of first surface 10a and first surface 10a,
Ink layer 20 is arranged on first surface 10a, and UV texture layers 30 are arranged on second surface 10b, and optical film 40 is arranged on UV
On texture layer 30, wherein ink layer 20 is the nonferrous layer of printing opacity, and optical film 40 is reflecting layer.In order to ensure that the color of diaphragm is imitated
Fruit, one layer of background color layer is set on optical film 40.
Above-mentioned ink layer 20 is sticked on glass cover-plate, and ink layer can weaken the bad order after optical coating, such as
Grain, dirt pits；Simple colour optics plated film realizes color effects, and color variation range is big, and each batch products color change is big,
Signed-off sample is relatively difficult, and plated film color has certain limitation, by the combination of ink layer 20 and optical film 40, can reduce diaphragm
Aberration, make color keep uniformity, while so that the glass cover-plate for the above-mentioned diaphragm that is sticked has grain effect.The present embodiment
Transparent base is preferably using PET (Polyethylene terephthalate, i.e. polyethylene terephthalate, abbreviation
PET), ink layer 20 uses semi permeability ink layer.
Fig. 2 shows the technological process of the preparation method of the diaphragm for cover plate of the embodiment of the present invention, the preparation method
Specifically comprise the following steps：
Step S01, a transparent base 10 is provided, transparent base 10 includes relative first surface 10a and second surface
10b；
Preferably, the thickness of transparent base 10 is preferably 0.125mm, and its length and width matches with glass cover-plate, this reality
The material for applying transparent base 10 in example is preferably PET base material, and certainly in other embodiments, the material of transparent base 10 can be
PMMA (Poly methyl Meth acrylate, i.e. polymethyl methacrylate, abbreviation PMMA) base material.
Step S02, make to form ink layer 20 in first surface 10a；
Specifically, according to corresponding harmonious colours color oil, color oil is added in ink main body, and stir 3~5min so that
Color oil is uniformly distributed, and web plate is arranged on first surface 10a, and ink is applied on web plate and printed, then will printing
Transparent base afterwards carries out baking-curing, forms ink layer 20.Preferably, the web plate in the present embodiment uses the web plate of 300 mesh,
When being toasted to transparent base, temperature is 80 DEG C, and baking time is 2 hours.
Step S03, made on second surface 10b and form UV texture layers 30；
Specifically, the impurity on the second surface 10b of transparent base 10 is disposed, the coating UV glue on UV roller moulds
Water, transparent base 10 is put into UV roller moulds, imprinted so that UV glue is pasted on second surface 10b, then will
Transparent base 10, which is put into UV stoves, to be solidified, to form UV texture layers 30 on second surface 10b.Wherein in order that obtaining transparent
Base material 10 and UV glue is fully pasted, and imprints after to UV glue row's bubble, after the completion of impressing, transparent base 10 is placed again
3~5min at room temperature so that UV glue is fully pasted with transparent base 10.Wherein, UV stoves energy set scope be 800~
1000mj/cm3, temperature are no more than 80 DEG C, avoid transparent base 10 because of high temperature deformation, ensure the outward appearance of diaphragm.Wherein, UV textures
Species can be CD textures, light beam texture, ripples texture etc..
Step S04, optical coating is carried out on UV texture layers 30 and forms optical film 40；
Specifically, transparent base 10 is cleaned first, the impurity on the surface of UV texture layers 30 is removed, by transparent base
10 put into coating machine, carry out vacuum pumping, and vacuum is evacuated to 6x10^-3 pas, and the pumpdown time is 25~30min, coated target
Material elects silica and titanium dioxide as, and plated film target carries out heating evaporation, and optical film 40 is formed on UV texture layers 30.This
In embodiment, the thickness of optical film 40 is 200nm, wherein, optical film 40 includes going back the set gradually on thickness direction
One silicon dioxide layer, titanium dioxide layer and the second silicon dioxide layer, the first silicon dioxide layer thickness are 70nm, titanium dioxide layer
Thickness is 50nm, and the thickness of the second silicon dioxide layer is 80nm, wherein the first silicon dioxide layer is close to UV texture layers 30.This implementation
Optical film 40 is simple reflectance coating in example, and plated film time is shorter, and realizes that color is imitated by optical coating in traditional handicraft
The plated film time of fruit is longer, and this scheme that color effects are implemented in combination with by optical film 40 and ink layer 20, cost is lower,
And color has more selectivity.
Step S05, made on optical film 40 and form background color layer 50.
Specifically, background color layer 50 includes the multi-layered soles chromatograph set gradually in a thickness direction, can pass through multiple off-set oil
Ink is formed.Preferably, background color layer 50 includes the first background color layer, the second background color layer and the 3rd background color layer being sequentially overlapped, wherein the
One background color layer is close to optical film 40, and in the first printing black ink of optical film 40, baking temperature is 80 DEG C, baking time
30min, form the first background color layer that thickness is 7 μm；Second printing black ink, baking temperature are 80 DEG C, baking time
30min, form the second background color layer that thickness is 10 μm；Third printing black ink, baking temperature are 80 DEG C, baking time
60min, the 3rd background color layer that thickness is 10 μm is formed, one side background color layer 50 is advantageous to the stickup of diaphragm, for example, when diaphragm glues
When being affixed on mobile terminal bonnet, background color layer 50 can stably be pasted on bonnet；On the other hand, background color layer 50 can ensure diaphragm not
Transparency so that the pattern texture effect of diaphragm is more preferable.
Embodiment 2
As shown in figure 3, the diaphragm of the present embodiment 2 and the difference of embodiment 1 are that UV texture layers 30 are arranged on ink
On layer 20, i.e. the second surface 10b of transparent base 10 is not processed.
Fig. 4 shows the diaphragm fabrication processing figure of the present embodiment 2, wherein, step S01', step S02', step
S04', step S05' are identical with the step S01 in embodiment 1, step S02, step S04, step S05 respectively, and difference exists
It is to make to form UV texture layers 30 on ink layer 20 in step S03'.
After the diaphragm of the present embodiment 2 completes, adhesion coating can be set on background color layer 50, diaphragm is pasted on plastic cover
On plate so that plastic cement cover plate has preferable color and grain effect.Certainly in other embodiments, can be in transparent base 10
Second surface 10b set optical cement, diaphragm is pasted on glass cover-plate.
A kind of preparation method of diaphragm for cover plate disclosed by the invention, technique is simple, and plated film time is short, processing cost
Low, diaphragm can be reduced the aberration of diaphragm, make color keep uniformity, be caused simultaneously by the combination of ink layer and optical film
