Preparation method of anti-dazzle high borosilicate glass

Abstract

The invention discloses a preparation method of anti-glare high borosilicate glass. The anti-glare preparation method comprises the following steps: S1, preparing an etching solution: mixing ammonium bifluoride, potassium bifluoride, ammonium fluoride, sulfuric acid, titanium dioxide and a modified filler, uniformly stirring, and adding into distilled water; S2, pre-cleaning: cleaning the high borosilicate glass to be treated; S3, performing local protection: covering the part which does not need to be etched with a shielding film; and S4, etching: putting the high borosilicate glass treated in the S3 into an etching solution for soaking, taking out the high borosilicate glass and drying the high borosilicate glass. The preparation method has the advantages that the activated carbon is added into the modified filler, so that the dissolving speed of the etching liquid can be increased, and the etching liquid can play a better role in a short time; a binder is added into the modified filler, so that the etching liquid can be in better contact with the high borosilicate glass, and the etching effect is improved; and a wear-resistant agent is added into the modified filler, so that the etched high borosilicate glass has good wear resistance, and the anti-dazzle effect is further improved.

Description

technical field [0001] The invention relates to the technical field of detection and production of float glass, in particular to a preparation method of high borosilicate glass anti-glare. Background technique [0002] High borosilicate glass is made by using the property of glass to conduct electricity at high temperature, through heating inside the glass to realize glass melting, and processed by advanced production technology. High borosilicate glass has a very low coefficient of thermal expansion, high temperature resistance, 200-degree temperature change resistance, acid resistance, alkali resistance, water resistance, and excellent corrosion resistance. These characteristics of high borosilicate glass determine that it is stronger than ordinary sodium silicate glass. Difficult to process and handle, etch with the general frosting method, the frosting effect obtained is poor, and the frosting particles are uneven.
