Anti-glare glass forming method and product thereof

Abstract

The invention relates to an anti-glare glass forming method and a product thereof. The method mainly comprises the step of spraying a matt ink on a surface of a glass substrate by an inkjet printer, and then heating and drying the matt ink on the glass substrate by a heating device, so as to form a matt layer on the surface of the glass substrate. Therefore, the inkjet printer can accurately control the spray amount of the matt ink, patterns, the printing density and the like, so that formation of a matt surface with an anti-glare effect or with various matt degrees on the surface of the glasssubstrate is facilitated.

Description

technical field [0001] The invention relates to a method for forming anti-glare glass and its products, especially a method for forming a fog layer with anti-glare effect or various haze changes on the surface of a glass substrate by inkjet technology and its products. Background technique [0002] Existing matte processing methods for glass surfaces mainly include sandblasting, chemical etching, and spray gun spraying. Among them, sandblasting is to use high-pressure air to spray corundum onto the glass surface through a sandblasting gun to cause impact, so that many granular depressions are formed on the glass surface, thereby forming a foggy effect. However, the method of using corundum to impact the glass surface will make the glass The strength is reduced, and it is easy to crack on the matte surface. There are also places that do not need sandblasting, and a protective film must be pasted on the glass surface before sandblasting to prevent the matte surface from being ...

Problems solved by technology

Among them, sandblasting is to use high-pressure air to spray corundum onto the glass surface through a sandblasting gun to cause impact, so that many granular depressions are formed on the glass surface, thereby forming a foggy effect. However, the method of using corundum to impact the glass surface will make the glass The strength is reduced, and it is easy to crack on the matte surface. There are also places that do not need sandblasting, and a protective film must be pasted on the glass surface before sandblasting to prevent the matte surface from being covered by the protective film. Therefore, the existing sandblasting The matte surface method is quite time-consuming and labor-intensive in construction, and the high-pressure air can not accurately control the amount, force, and range of spraying of the corundum, which also reduces the quality of the glass matte surface.

[0003] The method of chemical etching to form the glass surface is mainly to coat the glass surface with chemicals such as hydrofluoric acid, so as to corrode and damage the glass surface, so as to produce a concave-convex effect on the glass surface, but the chemical such as hydrofluoric acid is highly corrosive and Volatile and highly toxic liquids are not only easy to cause environmental pollution, but also very easy to be harmed by the corrosive and toxic chemicals during the etching process, which will cause harm to the human body. In addition, the chemical etching process is also quite complicated and time-consuming , and the degree of corrosion is not easy to control, the strength of the glass where it is etched by chemicals will also decrease, and it is prone to breakage in use

[0004] The spray gun spraying method is to make the high-pressure air pass through the spray gun to spray the paint on the glass surface, so that the glass surface will be uneven through this layer of paint. Protective film, and because the paint is sprayed on the glass surface by using high-pressure air, the amount of paint sprayed, the spraying force and the spraying range cannot be accurately controlled, which affects the quality of the glass matte surface. In addition, the existing sandblasting, chemical Glass matte processing methods such as etching and spray gun spraying cannot accurately control the degree of atomization of the glass matte surface, so it is also difficult to form the effect of changing the depth of haze
