Method for preparing stone jade porcelain polished tile

Abstract

The invention discloses a method for preparing a stone jade porcelain polished tile and belongs to the technical field of environment-friendly preparing of a wear-resisting pollution-resisting polished tile. On the basis of conventional raw materials, alpha-alumina with a large proportion is added into the porcelain polished tile; after blank preparing and application of slurry, the porcelain polished tile is dried with microwaves and treated for twice drying before being fired so that the moisture content of each ingredient has the better evenness. In the preparing method, nano-alumina sol and alpha-alumina powder are combined to reduce the firing temperature and the product manufacturing cost, intensity and resistance to acid and alkali corrosion of the product are improved; surface powder secondarily applied and an ink jetting and infiltrating technique are combined so that the beautiful decoration effect can be achieved and the porcelain polished tile can reach MOHS hardness of the jade; zirconium is not added into the entire formula, and thus the porcelain polished tile is healthy and environmentally friendly and has realistic jade textures.

Description

technical field [0001] The invention belongs to the technical field of environmentally friendly preparation of wear-resistant and anti-pollution polished bricks, and in particular relates to a preparation method of stone jade porcelain polished bricks. Background technique [0002] Polished brick is a kind of bright brick made by grinding the surface of the whole body brick body, which belongs to a kind of whole body brick. Compared with whole body bricks, the surface of polished bricks is much smoother. Polished tiles are hard and wear-resistant, suitable for use in bathrooms, kitchens and other indoor spaces. Although polished tiles are favored by consumers because of their hardness, wear resistance, and suitable for large-scale indoor and outdoor paving, the concave and convex pores left by the polished tiles during production will trap dirt and dirt, making the surface easy to infiltrate. Pollutants, and even some tea poured on polished tiles will do nothing. At prese...
