Granite texture ceramic tile and preparation method thereof

Abstract

The invention discloses a granite texture ceramic tile and a preparation method thereof. A green body of the granite texture ceramic tile is prepared from the following chemical components in percentage by mass: 68 to 70 percent of SiO2, 18 to 19 percent of Al2O3, small than 1.0 percent of Fe2O3, small than 0.3 percent of TiO2, small than 0.5 percent of CaO, small than 1.5 percent of MgO, 2.5 to 2.8 percent of K2O, 2.0 to 2.5 percent of Na2O and small than 4.5 percent of ignition lost; a ground coat of the granite texture ceramic tile is prepared from the following raw materials in percentageby weight: 35 to 40 percent of potash feldspar, 8 to 10 percent of zirconium silicate, 10 to 15 percent of calcined kaoline, 7 to 10 percent of zinc oxide, 5 to 8 percent of barium carbonate, 13 to 17percent of barium carbonate and the balance of additives; overglaze raw materials of the granite texture ceramic tile are high temperature matte dry grains with mesh numbers of 10 to 120; the firingtemperature of the granite texture ceramic tile is 1210 to 1240 DEG C and the firing period of the granite texture ceramic tile is 150 to 160 minutes. By adjusting and optimizing a green body preparation process and a ground coat formula of the ceramic tile, the prepared ceramic tile has the advantages of natural and smooth texture, stronger stereoscopic effect in vision and sandstone particle hand feel of natural stones; the texture and color patterns of granite texture ceramic tile are exactly the same as those of natural granite materials, so that the needs of consumers are met.

Description

technical field [0001] The invention relates to the technical field of ceramic tiles, in particular to ceramic tiles with a granite texture and a preparation method thereof. Background technique [0002] Due to the radioactivity of some natural granite stones (seriously endangering people's health), environmental problems in the stone processing process, color difference in the paving process, high price, and lack of resources, the scope of use of natural granite stones is limited. At present, there are many types of artificial granite on the market, but its color, natural changes in texture, surface texture, and practicality are all incomparable with natural stone. Therefore, there is an urgent need in the market for a high-grade ceramic tile that achieves a "granite" decorative effect in terms of pattern texture, visual effect, texture, and touch to replace granite stone to meet consumer demand. [0003] How to combine the original ceramic tile production technology of th...
