Abstract
The invention discloses a preparation method of anti-glare film-coated AG glass, which belongs to the technical field of anti-reflection glass.
Description
Technical Field
The invention belongs to the technical field of antireflection glass, and particularly relates to a preparation method of anti-glare coating AG glass.
Background
The scattering effect of the rough surface is utilized to convert a large amount of incident light into diffuse reflection light, the diffuse reflection light does not bring obvious change to the transmittance, and the glass produced by the fine roughening is called AG glass. The glass is coated with one or more layers of transparent metal films or metal oxide films which can absorb heat. Antireflection glass, also called anti-reflection glass, AG glass for short, has a refractive index of about 1.52, and is also called "invisible glass" because the surface of the glass is coated with a transparent film having a small refractive index, so that the reflected light from the upper and lower surfaces of the film interferes with each other to maximize the transmittance, and the transmission image is clear as if the glass is invisible. The antireflection glass is also called as "non-reflection glass". Glass capable of reducing reflected light. The surface of the glass is coated with a film with a refractive index smaller than that of the glass so as to reduce the reflection amount of light. In the prior art, a layer of magnesium fluoride film is coated by a vacuum evaporation coating method, the reflectivity of magnesium fluoride is low, the transmittance of magnesium fluoride is less changed along with the temperature change, the magnesium fluoride film can be used as protective glass used for exhibition windows, pictures, electronic instruments and the like, infrared window glass and the like, and the existing antireflection glass on the market mainly comprises the following components: the vacuum sputtering coated glass, the gel-sol coated glass and the special ultra-white cloth grain glass for packaging the solar cell can generate diffuse reflection even under the strong light condition, further reduce the reflection of the screen, improve the visibility and the brightness of a display picture, enable the image to be clearer and the color to be more saturated, thereby generating good visual effect, creating a clear and transparent visual space and enabling an observer to experience better visual enjoyment. With the advance of urbanization, high-rise buildings built in various places increasingly adopt glass curtain walls as decorations, and the problem of light pollution caused by the glass curtain walls is becoming serious. On the one hand, light pollution is a fierce in making an accident, under the blazing of burning sun, a traffic signal lamp and a running vehicle can pass through a building glass curtain wall beside a passage or at a traffic intersection to generate reflected light, and the reflected light can cause sudden temporary blindness and visual illusion to a driver, thereby seriously harming pedestrians and driving safety. On the other hand, the glass curtain wall near the residential area can reflect light to surrounding buildings, and certain troubles are inevitably brought to residents living nearby. Light pollution caused by reflected light is difficult to eliminate or reduce by means of decomposition, conversion or dilution and the like other pollution, so that the antireflection glass becomes an ideal material for high-grade building glass. The polythiophene synthesizing process includes mainly chemical oxidation polymerization, electrochemical polymerization, enzyme catalytic oxidation and coupling polymerization with transition metal element as medium. In daily life, people have experience of being attacked by glare, wherein part of the experience is from a glare light source, and part of the experience is from glare reflection. For example, when a computer is operated, due to the existence of the glass show window, the liquid crystal display screen and the liquid crystal touch screen cannot clearly see the displayed content due to reflection. The glass show window made of the antireflection glass can effectively solve the problem of glare pollution. The antireflection glass has the advantages that the surface light reflectivity of the antireflection glass is reduced and the perspective performance is enhanced by adopting a spraying method, a sol-gel immersion plating method, a magnetron sputtering method, a vacuum evaporation method or an acid etching method, but the magnetron sputtering method has relatively complex process and high requirements on environment and equipment, so the cost is higher, the vacuum evaporation method has relatively complex process and relatively high cost, the antireflection glass is not corrosion-resistant and has poor scratch-resistant performance under severe conditions such as strong light irradiation or outdoor wind, rain and the like, the antireflection glass is easy to wear and shine after being used for a period of time, a coating layer is easy to fall off or change color and lose the antiglare effect, and for example, Chinese patent CN2017109774660 discloses wear-resistant fingerprint-resistant frosted glass and a preparation method; in view of the above problems, a person skilled in the art needs to develop a method for preparing an anti-glare coating AG glass to meet the existing performance requirements and market requirements.
