Problems solved by technology

This method is too costly and has low production efficiency. At the same time, this method is limited by the size of the vacuum coating machine, and it cannot be implemented for slightly larger-sized glass.
[0004] The surface activity of glass is relatively high. Generally speaking, it does not have "water repellency" and "oil repellency", or is not "slippery" enough. Therefore, the glass used in touch screens has a bad touch. The current method is also through vacuum coating. The way to coat the glass surface with a layer of fluorine-containing low surface activity material
Similarly, the cost of this approach is too high and the production efficiency is low. At the same time, this approach is limited by the size of the vacuum coating machine, and it cannot be implemented for slightly larger-sized glass.
For the field of solar energy, when there is dirt attached to the surface of the glass without coating, it will affect the power generation efficiency, especially for large-scale solar generators placed in the field, the maintenance and cleaning work is very heavy

Abstract

The invention discloses coated glass with optical characteristics and anti-fouling property and a preparation method thereof. The coated glass comprises a glass matrix, wherein an optical nano layer and an anti-fouling nano layer are orderly attached to the glass matrix and are bonded through a chemical bond; the optical nano layer comprises an antireflection nano layer and / or an anti-dazzle optical nano layer. The preparation method of the coated glass disclosed by the invention is not affected by the size of vacuum coating equipment, and is high in production efficiency and low in production cost. The light transmissivity and the anti-fouling and anti-dazzle abilities of the prepared coated glass are effectively improved; the coated glass can be widely applied to the fields of electrons, buildings, energy sources, automobiles and the like, and is especially applicable to touch screen glass and solar glass at the surface of a display.

Description

Technical field [0001] The invention relates to the field of coated glass, in particular to a coated glass with optical properties and antifouling properties and a preparation method thereof. Background technique [0002] The application range of glass materials is very wide. In the fields of electronics, construction, energy, automobiles, etc., the transmittance of ordinary colorless glass is below 92%, and the reflectivity of each surface is about 4%. Reflectivity reduces the light transmission efficiency, resulting in a significant drop in display effect and efficiency when applied to display modules, resulting in increased energy consumption and reduced device life; resulting in a decrease in power generation efficiency when applied to solar modules . [0003] At present, in order to increase the transmittance of glass, the usual method is to coat the surface of the glass with multiple optical anti-reflection coatings by means of vacuum coating. This approach is too costly an...
