Abstract

The invention relates to an anti-dazzle glass etching liquid and a preparation method thereof. The anti-dazzle glass etching liquid comprises the following raw materials in percentage by weight: 8.2-9.6% of H2SO4 (sulfate), 1.8-2.2% of Na2SiF6 (sodium fluosilicate), 4.5-5.5% of ZnCl (zinc chloride), 21.5-22.5% of NH4HF2 (ammonium bifluoride), 3.6-4.2% of CaF (calcium fluoride), 3.6-4.2% of (NH4)2SO4 (ammonium sulfate), 2.1-2.5% of BaSO4 (barium sulfate), 1.6-1.8% of viscosity adjuster, 1.8-2.2% of dodecyl glucoside, and 45-55% of water. The anti-dazzle glass etching liquid has the advantages that the defects of high cost and instability of the existing etching liquid are overcome; the cost is low, the surface particles of the product are fine, and the transmittance is high.

Description

technical field [0001] The invention relates to the technical field of anti-glare glass preparation, in particular to an anti-glare glass etching solution and a preparation method thereof. Background technique [0002] Glass is widely used in daily life because of its advantages such as high strength, excellent optical properties, and good long-term working stability (not easy to age). However, due to the high reflectivity of the glass surface, it often causes "glare attack", which is what we often call "light pollution". And trouble; when we stop in front of the glass window to explore the scenery inside the window, the reflection of the glass surface often prevents us from clearly observing the scenery inside the window, etc., all of which are caused by the light reflection on the glass surface. To reduce the impact of light emitted by the glass, matting the glass can have a good effect. [0003] Anti-glare glass can reduce the interference of ambient light, reduce the r...
