Problems solved by technology

For the existing automobile glass, when the automobile glass is in humid air or cold environment, because the temperature inside the car is higher than the temperature outside the car, 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 relates to the field of glass processing, and specifically discloses a preparation process of tempered glass. The preparation process of the tempered glass of the present invention is as follows: after the glass is physically tempered, an anti-fog layer is coated on the tempered glass, so that the tempered glass has a very good anti-fog effect, and the surface stress distribution of the tempered glass is even, High flatness, low probability of self-explosion of glass during cooling process, etc.

Description

technical field [0001] The invention relates to the field of glass processing, in particular to a preparation process of tempered glass. 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 automobile glass, when the automobile glass is in humid air or cold environment, because the temperature inside the car is higher than the temperature outside the car, 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, but its operat...
