Description

Processing method of leaf-shaped glass with surface

Technical Field

The invention relates to the technical field of glass processing, in particular to a processing method of leaf-shaped glass.

Background

With the rapid development of science and technology, people have higher and higher requirements on the functions borne by glass. From frosted glass used in private places to anti-dazzle glass of screens of vehicle-mounted/electronic products, scientific researchers try to realize and endow more functions and applications to glass through regulation and control of glass surface microstructures. However, the controllable synthesis of the glass surface microstructure has been realized by expensive technologies such as photolithography, etching, nanoimprint and the like, and the industrial application of the special glass with the surface microstructure is severely restricted due to the defects of expensive equipment, high subsequent maintenance cost and the like.

There are also many problems in the research of the general acid etching method for preparing the anti-glare glass, such as: the acid etching solution of the Chinese patent of a preparation method of anti-glare glass (publication No. CN 101314522B) needs to be aged for more than 6 hours, so that the preparation method is not suitable for large-scale industrial production, and the prepared glass has irregular surface and low haze which is only 2-8 percent. The frosting liquid, the preparation method and the application thereof and the method for preparing the anti-dazzle glass (publication number CN 108191253A) are Chinese patents, gas needs to be introduced in the preparation process, the process flow is relatively complex, and the prepared anti-dazzle glass has irregular surface appearance and low haze. In summary, the problems of complex formula of the acid etching solution, complex process flow, uncontrollable surface morphology, low haze and the like exist in the field at present.
