Embodiment 1

[0024] A kind of formula of etching solution used in the present invention, takes raw material by following weight ratio:

[0025] Ammonium bifluoride 10 parts

[0026] 30 parts of ammonium fluoride

[0027] Calcium Fluoride 5 parts

[0028] Barium sulfate 10 parts

[0029] Ammonium sulfate 5 parts

[0030] Sodium fluoborate 10 parts

[0031] Zinc chloride 10 parts

[0032] 20 parts concentrated sulfuric acid

[0033] 100 parts of water

[0034] The specific operation steps for preparing anti-glare glass are as follows:

[0035] (1) Weigh the raw materials according to the etching solution formula, mix them, stir them evenly, and age them at room temperature for 6 hours to prepare the etching solution;

[0036] (2) The surface of the glass sample is cleaned with absolute ethanol and dried;

[0037] (3) Cover the side of the sample that does not need to be etched with self-adhesive (ordinary transparent glue);

[0038] (4) Put the glass sample in the etching solution,...

Embodiment 2

[0041] A kind of formula of etching solution used in the present invention, takes raw material by following weight ratio:

[0042] Ammonium bifluoride 10 parts

[0043] 30 parts of ammonium fluoride

[0044] Calcium Fluoride 5 parts

[0045] Barium sulfate 10 parts

[0046] Ammonium sulfate 5 parts

[0047] Sodium fluosilicate 10 parts

[0048] Zinc chloride 10 parts

[0049] 20 parts concentrated sulfuric acid

[0050] 80 parts of water

[0051] For the specific operation steps of preparing anti-glare glass, refer to Example 1, but the aging time is 10 hours.

[0052] The surface particles of the prepared anti-glare glass sample are fine, about 10-20 microns, and evenly distributed. According to the photoelectric haze meter, the light transmittance of 4 mm thick glass can reach 87.6%, and the haze is about 3.5%.

Embodiment 3

[0054] A kind of formula of etching solution used in the present invention, takes raw material by following weight ratio:

[0055] Ammonium bifluoride 15 parts

[0056] 30 parts of ammonium fluoride

[0057] Calcium Fluoride 5 parts

[0058] Barium sulfate 10 parts

[0059] Ammonium sulfate 5 parts

[0060] Sodium fluosilicate 10 parts

[0061] Zinc chloride 5 parts

[0062] 20 parts concentrated sulfuric acid

[0063] 100 parts of water

[0064] For the specific operation steps of preparing anti-glare glass, refer to Example 1.

[0065] The surface particles of the prepared anti-glare glass sample are fine, about 10-20 microns, and evenly distributed. According to the photoelectric haze meter, the light transmittance of 4 mm thick glass can reach 87.4%, and the haze is about 6.3%.

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 dried by 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. ...
