In the traditional process, after edging, the size of the brick body is shaped, and due to the limitations of the clean and bright and antifouling process, the brick body edge often has the defects of dark edge, low luminosity and poor antifouling effect, and a small amount of waste products are caused by corner breakage and edge rot. For some polished tiles with less demanding gloss (75-85 deg.), the effect of this defect is not very significant; this drawback is not allowed for some polished tiles of high gloss (95-100 °). Especially, after adjacent floor tiles are spliced together for a period of time, the area of the black edge is doubled and becomes more prominent, and the requirements of customers on high-grade floor tiles are difficult to meet.

As an improvement of the scheme, the anti-fouling liquid is formed by mixing two kinds of organic silicon oil which can generate polymerization reaction, wherein one kind of organic silicon oil is hydrogen-containing silicone oil, and the other kind of organic silicon oil is one kind of alkyl modified silicone oil, polyether modified silicone oil, epoxy modified silicone oil and hydroxyl modified silicone oil.
As an improvement of the above scheme, the antifouling liquid is a solvent-based antifouling liquid, and the solvent-based antifouling liquid comprises the following raw materials in parts by weight:
