Embodiment 1

[0016] A formula of anti-glare glass product etching solution is composed of the following raw materials in weight ratio:

[0017] 17 parts of ammonium fluoride

[0018] 2.5 parts of ammonium sulfate

[0019] Potassium sulfate 2.5 parts

[0020] Calcium fluoride 2.5 parts

[0021] 8 parts of sulfuric acid (concentration 98%)

[0022] 60 parts of water.

[0023] The specific operation steps of the anti-glare glass product etching process:

[0024] (1) Weigh the raw materials according to the composition of the formula, mix them at room temperature, stir evenly, put them in a container and age them for 24 hours, and make an etching solution;

[0025] (2) cleaning and drying the pre-etched flat glass with an organic solvent mixed with glycerol;

[0026] The composition of the organic solvent is: 5-10 parts of isopropanol, 5-10 parts of acetone, 70-120 parts of absolute ethanol, 10 parts of butyl acetate and 3-8 parts of glycerol.

[0027] (3) Shield the side of the glass t...

Embodiment 2

[0032] A formula of anti-glare glass product etching solution is composed of the following raw materials in weight ratio:

[0033] 9 parts of ammonium bifluoride

[0034] 3 parts ammonium sulfate

[0035] 3 parts potassium sulfate

[0036] 3 parts calcium fluoride

[0037] 24 parts of hydrochloric acid (concentration 34%)

[0038] 75 parts of water.

[0039] For the specific operation steps of the anti-glare glass product etching process, see Example 1, but the aging time is 30 hours. The cleaned glass uses paraffin to shield the side of the glass that does not need to be etched, and the glass is immersed in the prepared After soaking in the etching solution for 10 minutes, the surface particles of the prepared glass product are fine and fine, and the anti-glare effect is good.

Embodiment 3

[0041] A formula of anti-glare glass product etching solution is composed of the following raw materials in weight ratio:

[0042] 20 parts of ammonium fluoride

[0043] 2.8 parts of ammonium sulfate

[0044] Potassium sulfate 2.8 parts

[0045] 2.8 parts of calcium fluoride

[0046] 30 parts of hydrochloric acid (concentration 34%)

[0047] 65 parts of water.

[0048] For the specific operation steps of the anti-glare glass product etching process, refer to Example 1, but the aging time is 36 hours, and the glass is immersed in the prepared etching solution for 8 minutes. The surface particles of the prepared glass product are fine and The dazzle effect is good.

Abstract

The invention relates to a formula of etching liquid of anti-dazzle glassware and an etching process. Raw materials of the formula proportion by weight comprise: ammonium fluoride holding 17-24 parts or ammonium hydrogen fluoride holding 8.5-12 parts, ammonium sulfate holding 2.5-3 parts, potassium sulfate holding 2.5-3 parts, calcium fluoride holding 2.5-3 parts, sulfuric acid holding 8-12.5 parts or hydrochloric acid holding 24-37.5 parts and water holding 60-75 parts. The process comprises: (1) weighing the raw materials according to the formula of the etching liquid, then mixing, uniformly stirring and ageing to formulate the etching liquid, (2) rinsing and drying pre-etched glass by organic solvent mixed by glycerol, (3) shielding one face of the rinsed glass needing not be etched and (4) immersing the glass in the formulated etching liquid for soak, then taking out the glassware and preparing anti-dazzle glass finished products after washing by clear-water and drying. The invention has the advantages of simple process, easy operation, labor saving, subtle granular surface of the prepared glassware, high penetration rate, good anti-glare effect, durable service and the like.

Description

technical field [0001] The present invention relates to the field, and more particularly, to . Background technique [0002] Currently sold in the domestic market, the glass used for anti-glare purposes is generally realized by coating the glass surface. The anti-glare effect of coated glass is obvious, but the cost of coated glass is relatively high, and it is easy to fall off under harsh conditions such as strong sunlight or outdoor wind and rain, leaving scratches and spots on the surface, affecting transparency and appearance. Contents of the invention [0003] The purpose of the present invention is to provide an anti-glare glass product etching solution formula and etching process, which overcomes the disadvantages of using coated glass outdoors or under strong light conditions. The etching solution is relatively cheap and achieves the purpose of replacing coated glass. [0004] The formula of a kind of anti-glare glass product etchant of the present invention is m...
