Problems solved by technology

[0003] 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 provides a preparation process of tempered glass, which comprises the following steps: (1) cutting and edging a raw glass sheet according to design requirements; (2) tempering the cut and edged glass of the step (1) and then putting into a cleaning machine for cleaning; (3) putting the cleaned glass of the step (2) in a mixed solution of H2O2 with the mass concentration of 30% and H2SO4 with the mass concentration of 98% for ultrasonic activation, after activation, cleaning the glass to be neutral, and blow-drying; (4) plating an anti-fogging film on the surface of the blow-dried glass in step (3); (5) baking the film-plated glass of the step (4) in a baking oven, wherein the baking temperature is 150 to 250 DEG C, and the time is 50 to 60min; (6) putting the baked tempered glass of the step (5) into the cleaning machine for cleaning to obtain a finished product. The tempered glass of the invention has the advantages of uniform surface stress distribution, high flatness and a good anti-fogging effect.

Description

technical field [0001] The invention relates to the technical field of glass manufacturing, 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. [0003] 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 p...
