A processing method for leaf-shaped glass with surface

Abstract

The invention discloses a method for processing leaf-shaped glass on the surface, which comprises the following steps: S1, taking float glass and cleaning it; S2, encapsulating the cleaned float glass on one side to prevent acid corrosion protection; S3 1. Immerse the encapsulated float glass in the acid etching solution, the liquid level of the float glass and the acid etching solution is 45-90°; the acid etching solution contains 30-50% ammonium bifluoride, 4-10% Sulfuric acid, 10-18% potassium salt, 1-5% ammonium salt, and 30-40% water; S4, take out the float glass after acid etching, clean it, remove the sealing surface after cleaning, and obtain the unpackaged Leaf-shaped glass on the surface; the method can prepare high haze glass with microstructure on the surface, and the process is simple and the surface morphology is easy to control.

Description

technical field [0001] The invention relates to the technical field of glass processing, in particular to a method for processing leaf-shaped glass on the surface. Background technique [0002] With the rapid development of science and technology, people have higher and higher requirements for the functions carried by glass. From frosted glass used in privacy places to anti-glare glass for vehicle / electronic product screens, researchers try to realize and endow glass with more functions and applications through the regulation of glass surface microstructure. However, so far, the controllable synthesis of glass surface microstructures requires expensive lithography, etching, nanoimprinting and other technologies to achieve, because the equipment itself is expensive, the follow-up maintenance costs are high, and the shortcomings seriously restrict the special glass with surface microstructures. industrial application. [0003] There are also many problems in the research on ...

Problems solved by technology

But so far, the controllable synthesis of glass surface microstructures requires expensive lithography, etching, nanoimprinting and other technologies. Due to the expensive equipment itself, the disadvantages of high follow-up maintenance costs seriously restrict the special glass with surface microstructures. industrial application of

[0003] There are also many problems in the research of preparing anti-glare glass by ordinary acid etching method. For example, in the Chinese patent of "Preparation Method of Anti-glare Glass" (publication number CN101314522B), the acid etching solution needs to be aged for more than 6 hours. It is suitable for large-scale industrial production, and the surface of the prepared glass has irregular morphology and low haze, only 2%-8%

The Chinese patent of "A Frosting Liquid, Its Preparation Method, Application, and Method for Preparing Anti-Glare Glass" (publication number CN108191253A) requires gas to be introduced during the preparation process, and the process is relatively complicated, and the surface of the prepared anti-glare glass Irregular shape, low haze

All in all, there are currently problems in this field such as complex acid etching solution formula, cumbersome process flow, uncontrollable surface morphology, and low haze.
