Embodiment 1

[0035] Embodiment 1: have the preparation of low refractive index coating solution

[0036] 15 g CH 3 Si(OCH 3 ) 3 and 10 grams (CH 3 ) 2 Si(OCH 3 ) 2 Dissolve in 370 grams of absolute ethanol, add 1.5 grams of alumina powder with a particle size of 100 nanometers, stir evenly, then add 1.0 grams of a mixture of 70 wt% nitric acid and 10 grams of deionized water, and stir for 5 hours to obtain a solution a.

Embodiment 2

[0037] Embodiment 2: Pulling method prepares anti-glare film

[0038] Put solution a in a 500ml beaker and put it into a pulling machine, immerse the cleaned and dried 1.8×70×150 mm glass substrate in solution a, pull it at a speed of 2.5 mm per second, and then heat it in an oven to Keep at 350°C for 30 minutes to obtain an anti-glare coating with a thickness of about 150 nanometers.

[0039] Referring to the above method, coating solutions using different precursor compounds can be prepared, and non-conductive anti-glare coatings with different film thicknesses can be prepared by the pulling method. The coated glass prepared in this way has excellent resistance to ultrasonic cleaning and physical tempering. After 7-tank ultrasonic cleaning, the coating remains intact and does not fall off. Table 1 lists the basic properties of some coated glasses.

Abstract

The invention belongs to the field of manufacturing and application of optical glass, and particularly relates to a preparation method of anti-glare (AG) coated glass. The preparation method is applicable to production of nonconductive anti-glare coated glass with adjustable transmittance and haze in the fields of various displays, computer and electronic display touch screens, photo frames and electronic digital photo frames, automobile instruments, medical displays, cover plate glass for scripts and paintings and the like. The nonconductive anti-glare coated glass has a glass substrate, and a low-refraction and anti-glare additive-containing film layer deposited on the glass substrate, wherein the anti-glare film is deposited on the surface of the glass substrate by a solution dip-coating chemical method, and through heating curing, nonconductive coated glass with adjustable transmittance and haze is formed. The coated glass prepared by the preparation method provided by the invention has the transmittance of 75-98% and the haze of 0.5-20% at 550 nm and has excellent physical tempering resistance.

Description

technical field [0001] The invention belongs to the field of optical glass manufacture and application, in particular to a preparation method of anti-glare (AG) coated glass, which is suitable for various displays, computer and electronic display touch screens, photo frames and electronic digital photo frames, automotive instruments, medical displays and calligraphy and painting Cover glass and other fields, producing non-conductive anti-glare coated glass with adjustable transmittance and haze. Background technique [0002] When a beam of light is irradiated on the glass substrate, the transmission of light by the glass depends on five parts: reflection R, transmission T, diffuse reflection D, scattering S and absorption A of the glass, which follows the following equation: [0003] R+T+D+S+A=100% [0004] Flat ordinary, optical, or electronic glass, usually untinted, with negligible absorption, diffuse reflection, and scattering. For anti-glare glass, the purpose is to i...
