Problems solved by technology

The anti-reflection glass reduces the light reflectance of its own surface and enhances the perspective performance by using the spray coating method, sol-gel dipping method, magnetron sputtering method, vacuum evaporation method or acid etching method. However, the magnetron sputtering method is relatively It is complex and has high requirements on the environment and equipment, so the cost is high. The vacuum evaporation method is relatively complicated and the cost is high. It is not corrosion-resistant and has poor scratch resistance under harsh conditions such as strong light or outdoor wind and rain. After a period of use, it is easy to wear and shine, and the coating layer is easy to fall off or change color, losing the anti-glare effect. For example, Chinese patent CN2017109774660 discloses a wear-resistant and anti-fingerprint frosted glass and its preparation method; The defect of scratches, but due to the volatile nature of fluoride, the working environment is easily polluted, and there are certain safety hazards. For example, the anti-reflection glass disclosed in Chinese patent CN2019106601546 and its preparation method and application. Those skilled in the art for the above problems It is urgent to develop a preparation method for anti-glare coated AG glass to meet the existing performance requirements and market demand

Abstract

The invention discloses a preparation method of anti-glare coated AG glass and belongs to the technical field of antireflection glass. According to the preparation method of the invention, an insoluble and infusible polymer coating film is formed on the surface of glass through a plasma polymerization reaction; the prepared anti-glare coated AG glass has high light transmittance; the polymer coating film has good strength, is insoluble and non-fusible, has high surface hardness and good wear resistance and can significantly improve the light transmittance of the glass under the refractive index, so that the glass has a self-cleaning anti-static function, has high strength, high thermal stability, high-temperature sudden change resistance, high chemical stability, aging resistance and acidand alkali corrosion resistance, and is durable, good in flatness and long in service life in a severe use environment.

Description

technical field [0001] The invention belongs to the technical field of anti-reflection glass, and in particular relates to a preparation method of anti-glare coated AG glass. Background technique [0002] Using the scattering effect of the rough surface to convert a large amount of incident light into diffuse reflection light, it will not bring obvious changes to the transmittance. The glass produced by this kind of fine roughening is called AG glass. It is realized by sputtering one or more layers of heat-absorbing transparent metal film or metal oxide film on the glass surface. Anti-reflection glass, also known as anti-reflection glass, or AG glass for short, has a refractive index of about 1.52 for ordinary glass. Coating a transparent film with a small refractive index on its surface can make the reflected light on the upper and lower sides of the film interfere with each other to maximize the transmittance. The light rate makes the transmitted image very clear, as if t...
