Problems solved by technology

[0003] At present, most frosted glass is prepared by corroding glass with HF acid corrosion, but fluorine salts will be produced on the surface of the glass during the corrosion process. If the fluorine salts are not removed in time, the fluorine salts will hinder the progress of corrosion, making The glass corrodes unevenly, forming translucent glass, which cannot meet the requirements of practical application; and HF has high risk and is harmful to human body, so it should not be used in large quantities

Abstract

The invention relates to a glass frosting liquid and its preparation method and application. The preparation method of the glass frosting solution comprises the following steps: melting a metal salt to obtain a molten salt; adding a specific proportion of phosphate, inorganic alkali, alkaline auxiliary agent and adsorbent to the molten salt to obtain a glass frosting solution; wherein, The metal salt is selected from at least one of potassium nitrate, sodium nitrate and sodium chloride, and the adsorbent is selected from at least one of diatomaceous earth and aluminum oxide. The present invention first melts the metal salt to obtain the molten salt; then adds a specific proportion of inorganic alkali and alkaline additives to the molten salt, and utilizes the alkali and SiO in the glass to 2 and Al 2 o 3 Reaction, respectively reacting them into silicate and metaaluminate to achieve the purpose of corroding glass; at the same time, using phosphate together to further enhance the corrosion effect on glass; The reaction with glass can ensure uniform corrosion of glass and synergize the corrosion effect on glass.

Description

technical field [0001] The invention relates to the field of glass manufacturing, in particular to a glass frosting liquid and its preparation method and application. Background technique [0002] The light transmittance of glass is high, and it is easy to cause light pollution to the human body during use, and some liquids are prone to chemical reactions and deterioration when exposed to light. Therefore, it is of great significance to reduce the light transmittance of glass. Frosted glass corrodes or etches the glass surface through a chemical reaction to increase the roughness of the glass surface, thereby reducing the light transmittance. [0003] At present, most frosted glass is prepared by corroding glass with HF acid corrosion, but fluorine salts will be produced on the surface of the glass during the corrosion process. If the fluorine salts are not removed in time, the fluorine salts will hinder the progress of corrosion, making The glass corrodes unevenly and for...
