Embodiment 1

[0034] The invention provides a method for preparing diffuse reflection colored glass, comprising the following steps:

[0035] S1. Take the float glass and clean it with 10% surfactant (sodium dodecylbenzenesulfonate) first, then clean it with deionized water; put it into 10% sodium hydroxide solution Soak for 5 minutes, then soak in 10% dilute hydrochloric acid solution for 5 minutes, wash with water and ethanol in turn, and dry;

[0036] S2. Carry out single-sided packaging on the A side of the cleaned float glass (paste the anti-corrosion film on the A side), and do anti-acid corrosion protection treatment;

[0037] S3. Immerse the encapsulated float glass in the first acid etching solution, and perform acid etching treatment on the B surface. The first acid etching solution contains 18% hydrofluoric acid (concentration 40%) and 15% sulfuric acid in weight percentage (concentration 98%), 13% ammonium bifluoride, 13% potassium chloride, 5% ammonium sulfate, 3% zinc acetate...

Embodiment 2

[0042] The invention provides a method for preparing diffuse reflection colored glass, comprising the following steps:

[0043] S1. Take the float glass and clean it first with 10% surfactant (fatty alcohol polyoxyethylene ether) and then with deionized water; soak in 10% sodium hydroxide solution for 5 Minutes, then soaked in 10% dilute hydrochloric acid solution for 5 minutes, washed with water and ethanol in turn, and dried in the air.

[0044] S2. Encapsulate the cleaned float glass on the A-side and single-side to prevent acid corrosion protection.

[0045] S3. Immerse the encapsulated float glass in the first acid etching solution for acid etching treatment. The acid etching solution contains 16% hydrofluoric acid (concentration 40%) and 15% sulfuric acid (concentration 98%) by weight percentage , 12% ammonium bifluoride, 15% potassium chloride, 5% ammonium sulfate, 3% zinc acetate, 3% aluminum nitrate, 4% sodium chloride, and 27% water, soak for 30 minutes.

Embodiment 3

[0050] The invention provides a method for preparing diffuse reflection colored glass, comprising the following steps:

[0051] S1. Take the float glass and clean it. When cleaning, first use 10% surfactant to clean it, and then clean it with deionized water; put it into 10% sodium hydroxide solution for 5 minutes, and then put it into 10% sodium hydroxide solution. % dilute hydrochloric acid solution for 5 minutes, washed with water and ethanol in turn, and dried in the air.

[0052] S2. Encapsulate the cleaned float glass on the A-side and single-side to prevent acid corrosion protection.

[0053]S3. Immerse the encapsulated float glass in an acid etching solution for acid etching treatment. The acid etching solution contains 15% hydrofluoric acid (concentration 40%), 15% sulfuric acid (concentration 98%), 11 % ammonium bifluoride, 15% potassium chloride, 6% ammonium sulfate, 4% zinc acetate, 4% aluminum nitrate, 3% sodium chloride, and 27% water, soak for 40 minutes.

Abstract

The invention discloses a preparation method of diffuse reflection colored glass. The preparation method comprises the following steps: S1, cleaning float glass; s2, carrying out single-sided packaging on the float glass, and carrying out acid etching prevention protection treatment; s3, immersing the packaged float glass in an acid etching solution for acid etching treatment, wherein the acid etching solution is prepared from the following raw materials in percentage by weight: 15-18% of hydrofluoric acid, 15-18% of sulfuric acid, 11-13% of ammonium bifluoride, 13-15% of potassium chloride, 5-6% of ammonium sulfate, 3-4% of zinc acetate, 3-4% of aluminum nitrate, 3-4% of sodium chloride and 25-30% of water; s4, taking out and cleaning the float glass subjected to acid etching, and removing a packaging surface; and S5, coating the non-corrosion surface of the acid-etched glass by adopting a magnetron sputtering method and a ZrO2 target material under the conditions that the radio frequency power is 190-210W, the pressure is 1.0-1.4 pa and the Ar flow is 18-22sccm. The method can be used for preparing the high-haze diffuse reflection colored glass.

Description

technical field [0001] The invention relates to the technical field of glass processing, in particular to a method for preparing diffuse reflection colored glass. Background technique [0002] Colored glass has broad application prospects in building glass, photovoltaic cover glass, bathroom doors and windows and other fields. There are usually two ways to prepare colored glass, one is to add colorants to the raw materials in glass production; the other is to realize the color through later coating after the glass is formed. The way to achieve color by coating is more flexible in terms of color and transmittance. [0003] The patent with the publication number CN107881465A discloses a method for physical vapor deposition of a color film on glass. After physical vapor deposition of a layer of film, the ink of the corresponding color is printed on the surface to achieve coloring on the glass. The patent with the publication number CN213126087U discloses a double-coated mobil...
