Problems solved by technology

[0003] At present, the car display screens are all made of anti-glare glass with low fog and low roughness characteristics. Although it meets the requirements of normal use, in special environments such as strong sunlight, the driver and passengers will still be affected by the reflection of the screen, which will interfere with the driver and passengers. Correct judgment will bring great potential safety hazards to vehicle driving and personal safety

Abstract

The invention discloses a glass etching solution, which is composed of the following raw materials in weight percent: citric acid 5-15%, acetic acid 5-15%, NH 4 F 20‑30%, (NH 4 ) 2 SiF 6 5‑10%, K 2 SiF 6 1‑5%, (NH 4 ) 2 HPO 4 5-15%, viscosity modifier 0.5-1.5%, surfactant 0.5-1.5%, and the balance is water. At the same time, the corresponding preparation method and the method for preparing anti-glare glass by using glass etching solution are provided. The glass etching solution of the present invention has good stability and durability, and the prepared anti-glare glass has a required glossiness range of 100-130 for vehicle-mounted display, the haze of the anti-glare glass reaches 6-17%, and the roughness is 0.040-0.065 μm , its performance is better than the existing anti-glare glass.

Description

technical field [0001] The invention relates to the technical field of preparation of vehicle-mounted anti-glare glass, in particular to a glass etching solution, a preparation method thereof, and a method for preparing anti-glare glass using the glass etching solution. Background technique [0002] With the development of modernization, automobiles are used as people's daily means of transportation, and the automobile industry has ushered in unprecedented development. Display screens are one of the important components of vehicle display systems and vehicle imaging system equipment, and automobiles have their own unique safety features. Therefore, the display screen glass must also have safe and reliable all-weather display characteristics. Whether it is a traditional fuel vehicle or a pure electric vehicle, transparent plastic panels and glass cover materials are basically abandoned in the vehicle display system and vehicle imaging system equipment, and more anti-glare gla...
