Abstract

The invention discloses a ceramic tile and a preparation method thereof, and belongs to the technical field of production of ceramic tiles. The ceramic tile is characterized by comprising a blank material and a glaze material, wherein the blank material is prepared from the following raw materials in parts by weight: 15 to 20 parts of wollastonite, 15 to 20 parts of diatomite, 10 to 15 parts of iron tailings, 8 to 12 parts of light-burned dolomite, 7 to 10 parts of corundum powder, 3 to 5 parts of silicon carbide, 3 to 5 parts of active aluminium oxide and 2 to 4 parts of sodium silicate. Through improvement of formulas of the blank material and the glaze material, a product has low cost, high strength and strong adhesion force between the blank material and the glaze material.

Description

technical field [0001] The invention relates to the technical field of tile production, in particular to a ceramic tile and a preparation method thereof. Background technique [0002] Ceramic bricks are plate-shaped or block-shaped ceramic products produced by molding and sintering processes from clay and other inorganic non-metallic raw materials. They are commonly used building decoration materials and are widely used in residential buildings and public places on the walls or floors of buildings. For decoration, the current market requirements for ceramic tiles tend to be beautiful, light in weight, and high in strength. Ceramic tiles with properties such as heat preservation, sound insulation, and antibacterial have also been developed in the prior art. [0003] Chinese patent literature (publication number CN105272163) discloses an environmentally friendly ceramic brick green body, an environmentally friendly ceramic brick and a preparation method for the ceramic brick. ...
