Embodiment 1

[0040] Embodiment 1: have the preparation of high refractive index coating solution

[0041] 80 grams of Al(NO 3 ) 3 9H 2 Dissolve O in 210 grams of deionized water, add 210 grams of ethanol and 0.5 grams of German BASF (Koning) water-based paint wetting agent Hydropalat 875, and stir evenly to obtain solution a.

Embodiment 2

[0042] Embodiment 2: have the preparation of coating liquid of low refractive index

[0043] 15 g CH 3 Si(OCH 3 ) 3 and 10 grams (CH 3 ) 2 Si(OCH 3 ) 2 Dissolve in 370 g of absolute ethanol, add a mixed solution of 1.0 g of 70 wt% nitric acid and 10 g of deionized water, and stir for 5 hours to obtain solution b.

Embodiment 3

[0044] Embodiment 3: Pulling method prepares anti-reflection and anti-reflection film

[0045] 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 the first coating with a high refractive index. Solution b is placed in a 500ml beaker and placed in a pulling machine, the glass substrate plated with solution a and cured is immersed in solution b, pulled at a speed of 2.5mm per second, and then heated to 350°C in an oven to maintain After 30 minutes, the anti-reflection and anti-reflection coating is obtained. The thickness of the film layer is 80 nanometers for the first layer and 125 nanometers for the second layer.

[0046] Referring to the above method, coating solutions using different precursor compounds can be prepared, and non-conductive anti-reflection and anti-reflect...

Abstract

The invention belongs to the field of manufacturing and application of optical glass, and particularly relates to a preparation method of adjustable broadband anti-reflection (AR) coated glass. The preparation method is applicable to production of nonconductive coated glass with low reflection and high transmittance 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-reflection coated glass has a glass substrate, and a film layer having alternate high refraction and low refraction and deposited on the glass substrate, wherein the anti-reflection 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 high transmittance is formed. The anti-reflection coated glass prepared by the preparation method provided by the invention has the transmittance of 99% or above at 550nm and has excellent ultrasonic cleaning and physical tempering resistance.

Description

technical field [0001] The invention belongs to the field of optical glass manufacturing and application, in particular to a preparation method of adjustable broadband anti-reflection and anti-reflection (AR) coated glass, which is suitable for various displays, computers and electronic display touch screens, photo frames and electronic digital photo frames, automobiles Instruments, medical displays, and cover glass for calligraphy and painting, etc., to produce non-conductive coated glass with low reflection and high transmittance. 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] Thus, for AR or AR glass, the goal is to maximize T while minimizing (R+D+S+A). Generally uncolored flat ordinary, optical or elec...
