Abstract

The invention relates to a method for preparing an antireflection glass with an alkaline corrosion method through a Na2O-CaO-SiO2 system glass base, and aims to reduce reflectivity of a photovoltaic glass surface, a photo-thermal glass surface, a building glass surface, a room temperature glass surface and a decorative glass surface, and increase the transmittance, so as to increase a sunlight utilization rate, improve photoelectric or photo-thermal conversion efficiency, improve visual definition, and reduce light pollution. The purpose of the invention is achieved by the technical scheme that: placing a glass base body into an alkaline solution corrosion tank to be corroded; taking out, and cleaning, and then placing into an oven to be parched to obtain an antireflection glass. The method has the beneficial effects of low cost, good antireflection performance of the glass, high transmittance, and has a visible light transmittance of over 97%.

Description

technical field

[0001] The invention relates to a glass surface treatment method, in particular to a method for preparing anti-reflection glass by alkali corrosion. The anti-reflection glass prepared by the alkali corrosion method is suitable for solar thermal and photoelectric materials, architectural glass, glass walls of greenhouses and decorative glass. Background technique

[0002] In recent years, the world's demand for new energy has greatly promoted the development of solar energy utilization technology. China has become the largest producer of photovoltaic and photothermal products, but most of the photovoltaic and photothermal devices use glass with good light transmission As a protective or insulating material, if the reflection of the glass surface can be eliminated, the transmittance of sunlight can be increased, thereby further improving the efficiency of photoelectric or light-to-heat conversion, which has good economic benefits; at present, the glass curtain ...
