Method for preparing anti-dazzle glass

Abstract

The method relates to a method for preparing antiglare glass. The method comprises the following steps that: (1) an etching solution comprises the following compositions in portion by weight according to a formula: 10 to 15 portions of ammonium bifluoride, 20 to 30 portions of ammonium fluoride, 5 to 7.5 portions of calcium fluoride, 10 to 15 portions of barium sulphate, 5 to 7.5 portions of ammonium sulphate, 5 to 10 portions of sodium fluosilicate or 5 to 10 portions of sodium fluoborate, 5 to 10 portions of zinc chloride, 10 to 20 portions of concentrated sulphuric acid and 70 to 100 portions of water; raw materials are weighed, mixed, evenly stirred and matured for 6 to 10 hours at room temperature to prepare the etching solution; (2) the surface of a glass sample is cleaned and driedby absolute ethyl alcohol; (3) one surface of the glass sample which does not need to be etched is covered; and (4) the glass sample is put into the etching solution, marinated, taken out, washed by clean water and dried to produce a finished product of the antiglare glass. The method has simple process and easy operation; the prepared glass sample has the advantages of small particles on the surface and even distribution of the particles, high light transmissivity, good antiglare effect, etc.

Description

technical field [0001] The invention belongs to the field of glass preparation, in particular to a preparation method of anti-glare glass. Background technique [0002] In recent years, liquid crystal display screens, etc. have developed rapidly, and have been used in mobile phones, computers, TV monitors, etc., and a variety of multi-purpose products have been manufactured. In order to improve the resolution of such displays, the surface of these display screens generally has a layer with anti-glare function. This type of anti-glare technology can be roughly divided into two types: one is to directly treat the glass surface with anti-glare treatment; the other is to coat the surface with an anti-glare film. [0003] At present, the anti-glare glass sold in the domestic market is generally realized by coating the glass surface. Examples of these anti-glare films are as follows: Chinese patent CN1125996C discloses a wavelength-selective application film with glare control. ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a preparation method of anti-glare glass, which overcomes the shortcoming that the currently used coated glass is not durable, solves the glare problem of the glass under direct sunlight, and because its cost is relatively low, it can Achieve the goal of gradually replacing coated glass
