Scratch-resistant anti-glare microcrystalline glass, preparation method and application thereof

A preparation method for scratch-resistant anti-glare (AG) microcrystalline glass, comprising:

• cleaning and drying a raw sheet of microcrystalline glass;
• passing the dried microcrystalline glass through a horizontal sandblasting machine to obtain a sandblasted microcrystalline glass;
• and
• pickling, polishing and cleaning the sandblasted microcrystalline glass, repeating the pickling, polishing and cleaning 2 to 8 times, and drying, to obtain a scratch-resistant AG microcrystalline glass, wherein a time for each polishing of the pickling, polishing and cleaning is 6 minutes to 8 minutes,
• wherein the pickling, polishing and cleaning the sandblasted microcrystalline glass comprises:
• spraying, via a pickling device, a reagent on a surface of the microcrystalline glass, polishing the microcrystalline glass, and cleaning the sandblasted microcrystalline glass,
• the reagent comprises:
• in parts by weight, 20 to 30 parts of water, 15 to 25 parts of ammonium sulfate, 20 to 30 parts of barium sulfate, 12 to 16 parts of oxalic acid and 15 to 18 parts of ammonium acetyl fluoride.
