Process for producing anti-glare glass by using high-boron silicon and high-aluminium silicon glasses

Abstract

The invention discloses a process for producing anti-glare glass by using high-boron silicon and high-aluminium silicon glasses, wherein the method comprises the following steps: (1) weighing the raw materials according to the formula of a frosting liquid, mixing and stirring the raw materials evenly, curing the mixture for 24 -30 hours to prepare the frosting liquid; (2) after cleaning the glass to be frosted, carrying out protective treatment on one surface that is not needed to be frosted; (3) placing the protected glass into a pre-treatment liquor for further cleaning; (4) placing the treated glass into the cured frosting liquid to frost the glass for 30 -200 seconds, taking out the glass and cleaning the glass with water; and (5) placing the frosted glass into a polishing liquid to etch to obtain the anti-glare glass finished product. The invention solves the problem that the high-boron silicon and high-aluminium silicon glasses have large hardness and are difficult to be frosted; the process provided by the invention improves the hardness of the glass while guaranteeing the even frosting degree and good anti-glare effect; the product produced by the process provided by the invention has advantages of acid and alkali resistance and corrosion resistance.

Description

technical field [0001] The invention belongs to the field of glass preparation, in particular to a process for producing anti-glare glass with high borosilicate and high aluminosilicate glass. Background technique [0002] High borosilicate and high aluminosilicate glass are made by utilizing the conductive property of glass at high temperature, melting the glass by heating inside the glass, and processing it through advanced production technology. High borosilicate and high aluminosilicate glass have very low coefficient of thermal expansion, high temperature resistance, 200 degree temperature drastic change resistance, acid resistance, alkali resistance and water resistance, and excellent corrosion resistance. These characteristics of high borosilicate and high aluminosilicate glass determine its It is more difficult to process and handle than ordinary sodium silicate glass. Etching with general frosting method will result in poor frosting effect and uneven frosting partic...

Problems solved by technology

High borosilicate and high aluminosilicate glass have very low coefficient of thermal expansion, high temperature resistance, 200 degree temperature drastic change resistance, acid resistance, alkali resistance and water resistance, and excellent corrosion resistance. These characteristics of high borosilicate and high aluminosilicate glass determine its It is more difficult to process and handle than ordinary sodium silicate glass. Etching with general frosting method will result in poor frosting effect and uneven frosting particles.

There are many methods and techniques for making anti-glare glass in China, but they are mainly aimed at ordinary soda-lime-silicate glass, and there are no patents on the anti-glare effect of superhard glass such as high borosilicate, such as CN201010270000.5 One-step method of manufacturing low-reflection glass. This patent is mainly aimed at ordinary soda-lime-silica glass. Secondly, the anti-glare glass produced by the patented method can only have a small range of technical parameters such as gloss and light transmittance. Internal changes, can not meet the needs of customers, another example is CN200810038886.3 is anti-glare treatment for ordinary soda-lime-silica glass, through its solution ratio frosted high borosilicate glass, the anti-glare effect is not good and the surface frosted particles uneven
