Abstract

The invention discloses ceramic large board ground glaze. The ceramic large board ground glaze is prepared from the following raw materials in percentage by weight: 10 to 20 percent of potassium feldspar, 22 to 40 percent of sodium feldspar, 5 to 15 percent of nepheline, 20 to 30 percent of mixed kaolin, 5 to 15 percent of quartz powder, 10 to 20 percent of aluminum oxide, 5 to 10 percent of middle-temperature frit and 5 to 15 percent of zirconium silicate. According to the ceramic large board ground glaze disclosed by the invention, the ground glaze has excellent performance through adjustingraw material components and ratios thereof, and can be suitable for glaze spraying technological operation in a production process; meanwhile, after high-temperature firing is carried out, a glaze surface has no defects of needle holes, concave glaze, air bubbles and the like, so that the color, luster and lines have the advantage that a natural large rock plate is smooth and natural and the ground glaze also has a noble and elegant appearance of ceramic tiles; a ceramic large board has good pollution resistance and chemical corrosion resistance. The invention further discloses a preparationmethod of the ground glaze; the preparation method has the advantages of simple technology, strong controllable technological parameters and high production efficiency, and is suitable for large-scaleindustrial production.

Description

technical field [0001] The invention relates to the field of ceramic tiles, in particular to a ceramic tile bottom glaze. Background technique [0002] As a new type of ceramic product, ceramic slabs can carry richer texture elements than traditional ceramic tiles due to their super-large specifications. Combined with advanced technology, they can achieve excellent glaze quality. Ceramic large slabs have the advantages of simple and elegant decorative effects, less seams, avoiding dirt and dirt, and high construction and laying efficiency. Its market share in the high-end household products market will continue to increase. [0003] However, the size of ceramic large slabs exceeds the size of conventional ceramic tiles, which increases the difficulty of production. It is necessary to ensure the stability of the production process and improve the quality of the product. This requires that the glaze formula can be matched with the body and the kiln at the same time. Achieve s...
