Problems solved by technology

At present, the anti-fog treatment of the glass surface is usually to paint a layer of anti-fog layer on the surface, so that the glass surface has anti-fog performance, but this performance is formed by means of external means, the anti-fog time is not long, and long-term coating Brushing the anti-fog layer will have an impact on the glass surface

Abstract

The invention discloses a preparation method of antifogging glass. The method comprises the following steps: adding glass frit, alumina, titanium oxide, calcium carbonate and magnesium boride into a tempering furnace, heating the tempering furnace, carrying out heat insulation for a certain time, and preparing a glass blank through a mold; cooling the glass blank to 180-200 DEG C, and carrying outsteam treatment on the surface of the cooled glass blank for 5-10 min to obtain a steam-treated glass blank; and cooling the steam-treated glass blank to 78-80 DEG C, sprinkling ethanol on the surface of the glass blank in a spray manner, cooling the glass blank to room temperature, and washing the cooled glass blank with deionized water to obtain the antifogging glass. The antifogging glass prepared through the preparation method of the antifogging glass has a good antifogging effect under a high temperature condition, and also has a good antifogging effect under a low temperature condition.

Description

technical field [0001] The invention belongs to the technical field of glass preparation, and in particular relates to a preparation method of anti-fogging glass. Background technique [0002] The fogging on the glass surface greatly affects the projection of light. This is because many spherical tiny droplets are formed on the glass surface, and each droplet plays a role of transmission, scattering or irregularly reflecting the light in all directions. As a result, the external light cannot be directly transmitted, so the external image has a blurred effect that cannot be seen clearly. The greater the curvature of the water droplet, the more obvious the scattering and irregular reflection of light. Therefore, to prevent irregular reflections, it is necessary to reduce the curvature of the water droplet as much as possible, and to reduce its surface tension as much as possible. In this way, even if the water vapor condenses on the surface of the glass, it will not form wat...
