Description
Technical field
The utility model belongs to glass cover-plate field, and in particular to a kind of anti reflection glass cover board.
Background technology
Since two media interfacial refraction rate mutates, light spread speed in two media is inconsistent, thus occurs
Reflection is the main reason for causing energy loss.The reflection of light can be reduced by plating multilevel oxide film in glass surface,
The maximum reflectivity of for example, anti-reflection film of titanium oxide and silica membrane alternating deposit set at present in glass surface plating is only
It can reach and drop to 2%, and the glass cover-plate for plating traditional anti-reflection film can not clearly indicate pattern and word under strong light, can go out
Existing glare phenomenon.Therefore the antireflective rate and a kind of anti reflection glass cover board of offer for further decreasing glass cover-plate are that this field is non-
Normal urgent need.
Therefore, this field needs a kind of anti reflection glass that can be used in the terminals such as mobile phone, tablet and Vehicular display device
Cover board keeps picture apparent to improve the contrast of display image screen.
Utility model content
Therefore, the utility model provides a kind of anti reflection glass cover board, and the glass cover-plate includes plate glass and setting
UV-cured resin layer on plate glass, the UV-cured resin layer include the flat coating being wholely set and moth eye
Structure sheaf, the flat coating is covered on the plate glass and its thickness is 1~3 micron, array in the moth ocular structure layer
Multiple moth ocular structures, and each moth ocular structure and a diameter of the 210 of its i.e. bottom position of position of flat coating layer touch is distributed in formula
~290nm, the height of the moth ocular structure are 260~340nm, and the distance between the bottom dot of two neighboring moth ocular structure
For 310~390nm.
In a kind of specific embodiment, the thickness of the flat coating is 1.5~2.5 microns, the moth ocular structure
The height of a diameter of 230~270nm of bottom, the moth ocular structure are 280~320nm, the bottom of two neighboring moth ocular structure
The distance between dot is 330~370nm.
In a kind of specific embodiment, the plate glass is silicate glass.
In a kind of specific embodiment, the thickness of the plate glass is 0.2~0.8mm.
In a kind of specific embodiment, the moth ocular structure is the conical structure that top surface is cambered surface.
The utility model at least has the advantages that：The utility model is formed by nanometer transfer printing UV light-cured resins
The antireflection resin film layer of one layer of ocular structure containing moth and obtain a kind of anti reflection glass cover board, the maximum of the glass cover plate surfaces is anti-
The rate of penetrating can control below 0.3%.When the light of the utility model passes through moth ocular structure, refractive index is slowly varying, thus
Close to zero, light almost all penetrates glass for the refraction and reflection of glass plate upper surface light.
Description of the drawings
Fig. 1 is the structural schematic diagram of anti reflection glass cover board described in the utility model.
Fig. 2 is the reflectance test result figure of anti reflection glass cover board in the utility model embodiment.
Specific implementation mode
As shown in Figure 1, the utility model provides a kind of anti reflection glass cover board, the glass cover-plate includes plate glass 1
With the UV-cured resin layer 2 being arranged on plate glass, the UV-cured resin layer includes the flat painting being wholely set
Layer 21 and moth ocular structure layer 22, the flat coating is covered on the plate glass and its thickness is 1~3 micron, the moth eye
Multiple moth ocular structures, and position i.e. its bottom position of each moth ocular structure and flat coating layer touch is distributed in array in structure sheaf
A diameter of 210~290nm, the height of the moth ocular structure is 260~340nm, and the bottom circle of two neighboring moth ocular structure
The distance between point is 310~390nm.
Preferably, the thickness of the flat coating be 1.5~2.5 microns, the bottom of the moth ocular structure a diameter of 230~
The height of 270nm, the moth ocular structure are 280~320nm, and the distance between the bottom dot of two neighboring moth ocular structure is
330~370nm.
Preferably, the plate glass is silicate glass.
Preferably, the thickness of the plate glass is 0.2~0.8mm.
Preferably, the moth ocular structure is the conical structure that top surface is cambered surface.
Specifically, in the utility model, by transferring one layer of nanometer anti-reflection structure, this nanometer of antireflective in glass surface
Structure is bionical moth ocular structure, is that a kind of lower part is relatively thicker and the thinner nanostructure in top, the height of the moth ocular structure are
300nm is the cone shape of matrix arrangement, and base diameter 250nm, the spacing in the bottom center of circle of two neighboring moth ocular structure is
350nm.Most area is accounted in the upper air of moth ocular structure, and the lower air in moth ocular structure only accounts for fraction
Area, thus change in continuous gradient along depth direction in glass surface ray refractive index, refractive index change dramatically can be reduced and made
At reflex, so light refraction and reflection all close to zero.
The specific preparation method of the utility model is as follows：Surface is had Nano type minute concave-convex structure by the utility model
The PET molds of (the moth eye reverse geometry being made of resin) are pressed onto on unformed UV resins, so that ultraviolet after making it expose
Light-cured resin hardens, will be on the resin layer in fine structure transcription to glass cover-plate.Mold is removed again, the anti-reflection is made
Penetrate glass cover-plate.
The performance test of anti reflection glass cover board described in the utility model is as follows.Reflectivity detector model：Microcell reflects
Rate instrument GZ390M0.Follow-on test tests 25 sheet glass, and 3 points are tested per sheet glass, and test result is shown in Fig. 2 and table 1.
Table 1
From Fig. 2 and table 1 as it can be seen that glass cover-plate is after nano impression, the highest reflectivity on surface has descended to
0.3%.
It can be seen that by method described in the utility model, the resin nano Structure transfer with antireflective function is arrived
Glass surface.The maximum reflectivity of glass surface is set to drop to 0.3%, and the maximum reflectivity of traditional coated product glass surface
It is 2%, thus the maximum reflectivity of glass cover plate surfaces significantly declines.The technology can be widely applied to mobile phone glass cover board
On camera eyeglass, its reflectivity is reduced, improves the contrast of pattern, pattern is made to be more clear and perfect.
The above content is the further descriptions made to the utility model in conjunction with specific preferred embodiment, cannot recognize
The specific implementation for determining the utility model is confined to these explanations.For the ordinary skill people of the utility model technical field
For member, without departing from the concept of the premise utility, several simple deductions and replacement can also be made, all should be considered as
Belong to the scope of protection of the utility model.
