Problems solved by technology

[0006] The technical problem to be solved by the present invention is to provide a new optical glass for the anti-glare glass prepared by the prior art, which tends to have too high gloss, low definition and flash points under the condition of monochromatic strong backlight. And its preparation method, the optical glass prepared by this method has the advantages of high transmittance, low gloss, anti-glare, low haze, high definition, high resolution, ultra-thin, light weight, high strength, etc., the most The important thing is that compared with the anti-glare glass prepared by the existing technology, the manufacturing process is very environmentally friendly, and each target optical index can be flexibly adjusted according to the application requirements, and it has the characteristics of no flash point

Embodiment 1

[0054] This embodiment provides a plurality of pieces of optical glass, such as figure 2 As shown, each piece of said optical glass has only one said low gloss surface.

[0055] In order to better illustrate the specific implementation methods provided in this example, it is necessary to first introduce the testing instruments, testing principles and calculation methods used in testing the average roughness, haze and gloss in this example.

[0056] 1) Detection of the average roughness of the low-gloss surface

[0057] Testing instrument: SJ-210 Surface Average Roughness Measuring Instrument.

[0058] Test principle: When the stylus is directly across the measured surface of the workpiece, due to the peak and valley fluctuations of the measured surface profile, the stylus will move back and forth in the direction of the measured surface, so that this movement can be transmitted to the signal through the electronic device. Zoom in, and then output data and images about the a...

Embodiment 2

[0108] The optical glass provided in this embodiment has two above-mentioned low-gloss surfaces facing up and down. The average roughness and gloss of the two low-gloss surfaces and the haze of the optical glass were detected respectively according to a method mentioned in the embodiment.

[0109] It should be pointed out that gloss and average roughness are concepts for reflecting light on a single surface, while haze is a concept for penetrating light. Therefore, for optical glass with two opposite low-gloss surfaces, The Clapeyron-like function relationship it satisfies is:

[0110] in,

[0111] X is haze, the unit is "degree",

[0112] Y is the average roughness, the unit is "nm",

[0113] Z is glossiness, the unit is "degree",

[0114] K is a constant value of 10,

[0115] ε is a coefficient with a value of 0.5.

[0116] Through detection and calculation, the average roughness value of the upper and lower low-gloss surfaces is 316, the gloss value of the upper and ...

Embodiment 3

[0120] This embodiment provides a method for preparing optical glass, which is used to prepare a glass plate with opposite first and second surfaces to be processed into optical glass with a low-gloss surface as described in Embodiment 1, see Figure 4 , the preparation method comprises the following steps:

[0121] Step S1, protecting the second surface of the glass plate with a film.

[0122] Specifically, a corrosion-resistant plastic protective film is pasted on the second surface and four sides of the glass plate by using a laminator, the thickness of the protective film is 0.1±0.05mm, and within this range, the protective film It can effectively protect other surfaces of the glass display screen without significantly affecting the size of the glass display screen, facilitating its processing and moving. The function of the protective film is to protect other surfaces from corrosion and improve the quality of the product.

[0123] It should be noted that, in other embo...

Abstract

The invention discloses optical glass satisfying a Clapeyron-like functional relationship and having high light transmittance and low gloss. The optical glass has a low-gloss surface. The low-gloss surface has parallel light reflectance of less than 3%, gloss of 5 to 120 degrees and average roughness of 10 to 2000 nm. The optical glass has average visible light transmittance of more than 84% and haze of 0.5 to 80 degrees. The optical glass has the advantages of ultra-thinness, light weight, glare prevention, high strength, low haze, high definition and high resolution. Compared with the existing anti-glare glass, the optical glass has no flash point. The invention also discloses a preparation method of the optical glass. The preparation method comprises modification of the surface of a glass plate and polishing of the glass plate.

Description

technical field [0001] The present invention relates to the field of glass and its preparation, in particular to an optical glass and its preparation method, more specifically, to a glass used in mobile phones and flat display glass panels, projected capacitive touch screens and other consumer electronics, industrial control and other fields An optical glass conforming to the Clapeyron-like function relation of a display panel glass and a preparation method thereof. Background technique [0002] Anti-glare glass, also known as frosted glass or anti-reflection glass, is a special surface treatment of the glass substrate, so that it has a lower reflectance than ordinary glass, and basically does not affect the transmission of light. The reflectance of light is reduced by 8 % reduced to below 1%. Anti-glare glass can improve the viewing angle and brightness of the display screen, making the image clearer, the color more vivid, and the color more saturated, thereby significantl...
