Problems solved by technology
[0003] However, in the existing frosted glass surface preparation, the rough structure is usually a micron-scale rough concave-convex structure. This structure has been verified by experiments and found to have certain defects, specifically: the micron-scale rough structure on the frosted glass surface, It can play an anti-glare effect, but the light transmittance of the glass surface is low. In many occasions, it is difficult for users to see objects on the back of the glass.
The surface of this kind of frosted glass forms a layer of foggy feeling, and the clarity of the glass surface is low

The invention relates to the technical field of frosted glass surface treatment, in particular to an anti-glare (AG) glass nano-scale glass-frosting powder etching process. The surface of to-be-etchedglass has a nano-scale coarse structure, the nano-scale coarse structure has irregular nano-scale protrusions and recesses in terms of surface topography, and the size of the nano-scale protrusions and recesses ranges from 40 nm to 200 nm. The etching process for preparing frosted glass includes (1), preparation of glass-frosting powder; (2), cleaning of glass; (3), photoetching process; (4), hydrofluoric acid based etching; (5), glass frosting etching, to be specific, uniformly stirring to mix glass-frosting liquid, frosting the glass, performing frosting etching for 1-3 minutes, washing glass surfaces with great clean water after frosting etching to remove glass frosting powder, and further cleaning the glass surfaces with deionized water and absolute ethyl alcohol sequentially so as toobtain glass with cleaned surfaces. By the etching process, light transmittance and anti-glare effect can be guaranteed simultaneously; accordingly, the etching process has high practicable value andpromotion value.

technical field [0001] The invention relates to the technical field of frosted glass surface preparation, in particular to an anti-glare (AG glass) nanoscale frosting powder particle etching process. Background technique [0002] At present, in many technical fields of glass surface preparation, frosted glass provides better convenience for users in daily life based on its better anti-glare effect on the surface. [0003] However, in the existing frosted glass surface preparation, the rough structure is usually a micron-scale rough concave-convex structure. This structure has been verified by experiments and found to have certain defects, specifically: the micron-scale rough structure on the frosted glass surface, It can play an anti-glare effect, but the light transmittance of the glass surface is low.
