Abstract

The invention belongs to the technical field of glass material modification and application, and discloses a preparation method of flat glass with anti-glare and anti-reflection functions. The disclosed preparation method of flat glass with an anti-glare and anti-reflection functions comprises the following steps: mixing water, polyol, a complexing agent and alkali in a molar ratio of 55.6:(0.06-0.1):(0.001-0.015):(0.4-1.3) to prepare chemical etching composite liquid; and cleaning a to-be-treated glass substrate with a cleaning agent, washing the glass substrate with deionized water, placingthe glass substrate in the chemical etching composite liquid, and carrying out a chemical reaction at a temperature of 110 DEG C for 10 hours. The preparation method provided by the invention realizeslarge-area glass anti-reflection, the cost is low, the glass has an anti-glare function and the visible light transmittance of the glass can be improved by 6% or more.

Description

technical field [0001] The invention belongs to the technical field of modification and application of glass materials, and in particular relates to a preparation method of flat glass with anti-glare and anti-reflection functions. Background technique [0002] AR anti-reflection glass using vacuum sputtering and sol-gel coating technology is widely used in the fields of optics, solar photovoltaic and electronic information display. These methods have high production costs and complicated processes; chemical etching technology is currently the focus of preparing anti-reflection and anti-reflection glass The development trend, the glass body is etched by a chemical solution, and a relatively regular nano-sized pore-like structure is formed on the surface. This structure is equivalent to a layer of low refractive index film layer. After the light is interfered and extinguished, the reflection of the glass is reduced. Compared with other glass surface coating anti-reflection tec...
