Abstract

The invention provides a stoneware sheet and a preparation method thereof. The stoneware sheet comprises the following chemical components in percentage by weight: 55-68% of SiO2, 14-28% of Al2O3, 0.5-1.8% of Fe2O3, 0.2-1.5% of TiO2, 1-12% of CaO, 0.3-1% of MgO, 2-5% of K2O and Na2O and 5-30% of fiber reinforcer. The preparation method comprises the following steps: independently ball-milling and pulping the fiber reinforcer, mixing with other pulping raw materials, carrying out spray granulation, and dry-pressing to obtain the green body. The stoneware sheet has the advantages of favorable adhesiveness, high strength, favorable flatness, high resilience and flexibility, high abrasive resistance, favorable anti-fouling performance, fire resistance, high temperature resistance, long service life, no radioactive contamination, light weight and the like.

Description

technical field [0001] The invention relates to the technical field of building decoration materials, in particular to a stoneware veneer and a preparation method thereof. Background technique [0002] With the increase of product specifications, the thickness of general ceramic tiles is also increasing. Ceramic tiles consume more raw materials per unit area, which not only increases the load of the building, but also causes a large consumption of materials. Thin-slab bricks can save raw materials and reduce energy consumption in the preparation process, which has become the future development trend of the ceramic industry. [0003] Due to its certain water absorption, stoneware bricks are widely used in kitchen and bathroom floor decoration. However, stoneware bricks have the disadvantages of high water absorption and poor strength, making it difficult to make large-scale thin-slab bricks, which limits their application in modern architectural decoration.
