Problems solved by technology

For the existing architectural glass or automobile glass, generally in humid air or cold environment, due to the difference in internal and external temperature, the water vapor in the air condenses on the surface of the glass to form fog droplets, affecting the line of sight
There is a fan on the car, which can blow air to the windshield, and accelerate the air flow to facilitate the evaporation of water mist, but its effect is not good, and it cannot completely remove the fog
At present, it is generally used to coat the glass with an anti-fog agent composed of a surfactant to solve this problem, but its operation is cumbersome, so it is very necessary to develop a tempered glass that itself has anti-fog function

Abstract

The invention discloses a preparation method of tempered glass with anti-fogging performance. The preparation method comprises the following steps: firstly putting silicon dioxide, calcium oxide, aluminum oxide, zinc oxide, sodium oxide, lithium oxide and sodium carbonate into a toughening furnace, carrying out heating treatment for 30-40min to obtain the treated material; cooling and soaking the treated material into an anti-fogging modifier at a certain temperature under an inert gas protection condition, keeping for a certain period of time, taking out glass, cooling to a room temperature and cleaning the surface; and finally putting the obtained glass into hydrogen peroxide, taking out the glass after heating treatment, and cleaning to obtain the tempered glass with the anti-fogging performance. The tempered glass with the anti-fogging performance is capable of lastingly and continuously generating the anti-fogging effect in high-temperature and low-temperature anti-fogging experiments.

Description

technical field [0001] The invention belongs to the field of glass preparation, and in particular relates to a preparation method of tempered glass with anti-fog performance. Background technique [0002] Tempered glass is widely used in automobile, construction and other industries due to its advantages such as high mechanical strength, excellent temperature resistance and good safety. For the existing architectural glass or automobile glass, generally in humid air or cold environment, due to the difference in internal and external temperature, the water vapor in the air condenses on the surface of the glass to form fog droplets, affecting the line of sight. There is a fan on the car, which can blow air to the windshield, and accelerate the air flow to facilitate the evaporation of water mist, but its effect is not good, and it cannot completely demist. At present, it is generally used to coat the glass with an anti-fog agent composed of a surfactant to solve this problem,...
