Abstract

The invention discloses a production method for a glass surface without glare and with low reflection. The production method comprises: a glass substrate containing at least one surface to be processed is provided, a first etching solution is provided, and the first solution is formed through mixing of 10%-35% of water-soluble inorganic salts, 5%-60% of acid solution, 0.5%-5% of dispersants, 1%-10% of stabilizing agents, deionized water and the like; the first etching solution is applied on the surface to be processed of the glass substrate, a plurality of fine recessions are formed on the surface, the surface is roughened and the reflection of light is reduced; a second etching solution is provided, and the second etching solution is formed through mixing of hydrofluoric acid, inorganic acid, modifiers, deionized water and the like, the second etching solution is applied on the surface to be processed after the first etching production, the shapes of the fine recessions on the surface to be processed are subjected to passivation, the difference of depths of the recessions is lowered, the roughness of the surface to be processed is homogenized and the glossiness of the surface is raised, and therefore the light transmission of the glass surface is raised greatly, and a glass surface without glare and with low reflection and high light transmittance is formed.

Problems solved by technology

[0004] In addition, the aforementioned physical collision method uses wind pressure to hit the fine steel grit on the surface of the glass substrate in a high-speed spraying manner to roughen the surface to reduce the effect of reflected light, and perform polishing process after sandblasting to achieve Forming a glass surface with both anti-glare and anti-reflection performance; using physical collision to treat the surface of the glass substrate, although it can have the advantages of high efficiency, low cost and reworkability, but there are many uncontrollable factors in this technical method. For example, the service life of the consumables is short, the impact depth is different, the working environment is poor, and there will be static electricity; the polishing process after the aforementioned sandblasting is mostly mechanical grinding, and the stress generated when the glass surface material is removed during the polishing process often increases. Fragments of the glass substrate are caused, and because many pits of different depths and pore sizes are formed on the glass surface after sandblasting, although the use of mechanical grinding can remove part of the material on the glass surface, although it can improve the surface gloss and flatness, However, the anti-glare and anti-reflection effects that can be achieved are limited, and it is difficult to effectively improve the anti-glare effect and visual imaging quality of the display; it is known that in addition to the aforementioned mechanical grinding methods, wet etching methods can also be used for polishing processes. Wet etching is processed by etching solution, and the etching solution is a strong acid solution mixed with various compounds, usually with potassium bifluoride, calcium fluoride and other fluorides as the main components. In the strong acid solution, the hydrofluoric acid generated by the reaction erodes the glass surface to achieve the anti-glare effect; the current common problems in the polishing process by wet etching methods include: 1. The yield rate of finished products is low, and the subsequent surface polishing treatment takes a long time ; 2. The limitations of the production method are large, and the processing results are difficult to control. 3. The sour taste of the etching solution is too large, which seriously affects the production operation of personnel; 4. The etching solution is highly toxic and volatile, and has harmful effects on the skin and respiratory tract. Strong corrosiveness, which seriously endangers the health of workers; 5. The time required for etching processing is too long; 6. It cannot be produced in large quantities and efficiently; 7. The stability of the etching solution is poor and the effective life is short; and 8. Personnel costs Advanced; due to the immature technical means of common wet etching, there are still many shortcomings, so it is still unable to be applied to the mass production process
