Problems solved by technology

However, due to the problems in its processing technology, it is impossible to achieve a firm bond between the chemical coating and the original glass. After a period of use, the coating will fall off, which greatly reduces the self-cleaning effect of the glass.
In addition, the existing chemical coatings have relatively simple components and do not have the function of self-sterilization

Embodiment 1

[0025] In the present invention, the self-cleaning glass consists of a glass original sheet and a photocatalyst coating arranged on the surface of the glass original sheet, and the photocatalyst coating includes the following components by weight:

[0026] Anatase Nano Titanium Dioxide (TiO2) 2%-8%

[0027] Isobutanol 0.01%~2%

[0028] Lauryltrimethylammonium chloride 0.01%~2%

[0029] Sodium dodecylbenzenesulfonate 0.01%~2%

[0030] Silica sol 1%~15%

[0031] Ethanol 0.5%~10%

[0032] Water 70%~90%

[0033] Production technique of the present invention comprises the steps:

[0034] First, select and cut the original glass, and then use cerium oxide polishing powder to polish and edge the glass surface;

[0035] Surface pickling: Use hydrochloric acid with a concentration of 1% to 30% to pickle the glass surface;

[0036] Then use pure water to clean again; spray photocatalyst coating on the surface of the original glass sheet cleaned by pure water, and carry out high-t...

Embodiment 2

[0039] The composition of the original glass sheet and the photocatalyst coating of this embodiment is identical to that in Example 1;

[0040] The production process in the present embodiment is as follows:

[0041] First, select and cut the original glass, and then use cerium oxide polishing powder to polish and edge the glass surface;

[0042] Surface pickling: Use hydrochloric acid with a concentration of 1% to 30% to pickle the glass surface;

[0043] Then use pure water to wash again; spray silica sol on the surface of the original glass sheet cleaned by pure water, and perform high-temperature baking and drying at a temperature of 300°C to 500°C, and the baking and drying time is 1 to 5 hours; then Spray coating includes 2%-8% of anatase nano-titanium dioxide (TiO2), 0.01%-2% of isobutanol, 0.01%-2% of dodecyl trimethyl ammonium chloride, 0.01%-2% of ten A photocatalyst coating composed of sodium dialkylbenzenesulfonate, 0.5% to 10% ethanol, and 70% to 90% water; and ...

Abstract

A self-cleaning glass and its production are disclosed. The glass consists of glass raw sheet and light catalyst coating set on surface of glass raw sheet, which comprises anatase nano-titanium dioxide, isopropyl alcohol, sodium dodecyl benzene sulfonate, silicon sol, alcohol and water. The process is carried out by concentrating for glass raw sheet, cutting, polishing, edging, surface washing by acid, washing by pure water, baking and drying at high temperature and tempering treating. It's smooth and transparent, has excellent light catalytic and sterilizing functions, strong oxidative performance, and higher degradation rate.

Description

Technical field: [0001] The invention relates to a self-cleaning glass and a production process thereof, belonging to the field of glass processing. Background technique: [0002] The existing self-cleaning glass is usually coated with a layer of chemical coating on the original glass, and the chemical coating is used to realize the automatic cleaning of the glass surface. The self-cleaning glass has good hydrophilic properties. Under the irradiation of ultraviolet light, Self-cleaning glass has unique characteristics: photocatalytic activity, which can quickly decompose organic dirt attached to the glass surface into inorganic substances, thereby realizing the self-cleaning function of glass; light-induced superhydrophilicity, the contact angle of water is in Below 10°C, the surface of the glass is not easy to produce water droplets, but forms a water film on the surface of the glass and dries quickly. However, due to the problems in its processing technology, the firm com...
