Technical Field

The invention belongs to the field of ceramic tiles, and particularly relates to a preparation method of a medium-light ceramic tile.

Background

The ceramic tile is used as a building decoration material, and not only can be used for decorating buildings to ensure that the buildings are beautiful and gorgeous; moreover, the tile layer is adhered to the surface of the building, so that the erosion of the external environment to the surface of the building can be isolated, and the building is more durable. The super-clean and bright technology is a high-precision ceramic tile surface treatment method which is commonly adopted at present, and the method comprises the steps of repeatedly applying pressure to a ceramic tile through a polishing grinding head, grinding and polishing, so that nano silicon dioxide particles in nano liquid better penetrate into pores of the polished ceramic tile, pores and microcracks of the ceramic tile are blocked, and a special and continuous nano film is formed, so that the ceramic tile has a bright surface, the surface can effectively prevent pollutants from invading, and the ceramic tile has better antifouling performance.

However, the excessively bright ceramic tiles generate light reflection, which can stimulate the retina, so that the eyes can be tired and even the visual function can be reduced when the ceramic tiles live in the household environment with excessively bright walls and floors for a long time. Compared with a high-light ceramic tile, the high-light ceramic tile with the light reflection coefficient at 70 degrees has low light reflection coefficient, cannot cause light pollution, can avoid the problems in use, but has the pollution resistance which is generally accepted as a scaling problem in the industry, is easier to absorb and dirty than a bright face brick, and has the pollution resistance which hardly meets the market requirement, so that the application of the high-light ceramic tile is limited, and particularly, the low-light ceramic tile with the low light reflection coefficient at about 30 degrees is widely produced in China, but the product has poor luminosity, the surface effect is not beautiful enough, and certain limitation is realized in use.
