1. A preparation method for a high-wear-resistance far-infrared ceramic polished glazed tile, comprising:
applying a far-infrared overglaze on a green body;
ink-jet printing a pattern on the far-infrared overglaze;
applying a transparent far-infrared polished glaze on the pattern;
applying an abrasion-resistant far-infrared polished glaze on the transparent far-infrared polished glaze to produce a glazed body;
firing the glazed body to produce a fired body; and
polishing the fired body to obtain the high-wear-resistance far-infrared ceramic polished glazed tile, wherein
a chemical composition of the far-infrared overglaze comprises 63 to 73 percent by weight of SiO2, 16 to 24 percent by weight of Al2O3, 0.5 to 0.7 percent by weight of Fe2O3, 0.25 to 0.35 percent by weight of TiO2, 0.3 to 0.6 percent by weight of CaO, 0.4 to 1.0 percent by weight of MgO, 3.0 to 4.0 percent by weight of K2O, 1.5 to 2.5 percent by weight of Na2O, 3.2 to 9.6 percent by weight of ZrO2, 120 to 180 ppm by weight of Rb2O, 90 to 130 ppm by weight of Y2O3, and 1.1 to 1.5 percent by weight of loss on ignition,
a chemical composition of the transparent far-infrared polished glaze comprises 50 to 60 percent by weight of SiO2, 6 to 8 percent by weight of Al2O3, 0.2 to 0.3 percent by weight of Fe2O3, 0.25 to 0.35 percent by weight of TiO2, 5.5 to 8.5 percent by weight of CaO, 3.1 to 4.2 percent by weight of MgO, 3.5 to 6.5 percent by weight of BaO, 8.0 to 13.0 percent by weight of ZnO, 3.0 to 4.0 percent by weight of K2O, 1.0 to 2.0 percent by weight of Na2O, 100 to 155 ppm by weight of Rb2O, 70 to 110 ppm by weight of Y2O3 and 2.0 to 3.5 percent by weight of loss on ignition,
a chemical composition of the abrasion-resistant far-infrared polished glaze comprises 40 to 50 percent by weight of SiO2, 9 to 11.5 percent by weight of Al2O3, 0.2 to 0.3 percent by weight of Fe2O3, 0.25 to 0.35 percent by weight of TiO2, 6 to 8.5 percent by weight of CaO, 2.5 to 4.5 percent by weight of MgO, 9.5 to 13.0 percent by weight of BaO, 10.0 to 16.0 percent by weight of ZnO, 2.0 to 4.0 percent by weight of K2O, 0.6 to 1.0 percent by weight of Na2O, 60 to 110 ppm by weight of Rb2O, 40 to 80 ppm by weight of Y2O3, and 3.5 to 5.0 percent by weight of loss on ignition, and
the far-infrared overglaze, the transparent far-infrared polished glaze, and the abrasion-resistant far-infrared polished glaze include far-infrared feldspar powder to provide a far-infrared function, and the far-infrared feldspar powder contains a compound of magnesium aluminum silicate with a highly asymmetric lattice doped with impurity ions.
