Abstract

The invention discloses a high-hardness abrasion-proof ceramic brick. The high-hardness abrasion-proof ceramic brick comprises a blank body, a ground coat layer, a decorative layer and a high-hardnessabrasion-proof glazed layer from bottom to top, wherein the high-hardness abrasion-proof glazed layer comprises the following chemical components in percentage by weight: 68-75% of SiO2, 10-13% of Al2O3, 0.05-0.1% of Fe2O3, 0.01-0.03% of TiO2, 1-3% of CaO, 2-4% of MgO, 2-5% of K2O, 1.5-3% of Na2O, 0.1-0.3% of Li2O, and 1-2.5% of BaO, wherein loss on ignition is 2.5-4%. According to the high-hardness abrasion-proof ceramic brick disclosed by the invention, through controlling chemical constituents in glaze, high-silicon glaze is obtained, so that formation of the high-hardness abrasion-proof glazed layer at the later stage is guaranteed. The invention further discloses a preparation method of the ceramic brick. Through the nanocrystallization technology of raw materials and thickness matching of particle diameters of the high-silicon glaze, the defects of a glaze surface, for example, the glaze layer is easy to subject to cut glaze when the glaze layer is formed at the later stage areovercome, and the hardness and the abrasion resistance of the glaze surface of the ceramic brick are greatly improved.

Description

technical field [0001] The invention relates to the field of building ceramics, in particular to a wear-resistant ceramic brick. Background technique [0002] Ceramic tiles are the most important part of interior decoration, and the difference in their performance directly affects the scope of application. As a ceramic tile for paving, it needs to have better strength and wear resistance. Especially for the paving of the bottom surface in public places, hardness and wear resistance are particularly important. With the continuous expansion of ceramic tile categories, glazed tiles have gradually become the mainstream product in the market, and are widely used in home decoration and engineering construction decoration. [0003] In recent years, a series of high hardness and wear-resistant products have appeared on the market, such as diamond glaze and wear-resistant bricks. At present, the improvement of hardness and wear resistance is mainly to adjust the composition of the...
