Abstract
Frosted glass takes considerable research attention due to its simple preparation process and wide application prospect. Herein, acid dissolving salt solution chemical etching method was used to prepare anti-glare (AG) and anti-reflection (AR) glass, and the relationship between etching time and surface crystallization under the constant temperature and the same acid concentration was explored. Based on which, the chemical reaction mechanism was clarified, and the dynamic model of the particle growth of the surface of the etched glass was fitted. The results indicated that with the prolongation of the etching time, the content and size of the insoluble fluorosilicate particles formed on the glass surface increased, and the growth of crystals conformed to the power-law model. Due to the appropriate amount and size of the precipitated insoluble fluoride salts, a light trapping structure was formed on the glass surface to capture incident light so that the transmittance of the glass was increased to a certain extent, and the specular reflection of the surface was effectively transformed into diffuse reflection, achieving an anti-glare effect. The glass etched in the frosting solution with pH = 3 for 15 min showed the best optical properties, with the transmittance of 89%, while the average light reflectance was reduced by 75%. It provides the possibility for the protection of historical buildings.
