A preparation method for a hard wear-resistant polished glazed ceramic tile, comprising the following steps: Step: pressing and then drying body powder to form a green brick; Step: applying a ground coat on the surface of the green brick; Step: inkjet-printing a pattern on the surface of the green brick having the ground coat, and applying an isolation glaze, the chemical composition of the isolation glaze comprising 42 to 50 percent by weight of SiO 2, 21 to 25 percent by weight of Al 2 O 3, 0.16 to 0.46 percent by weight of Fe 2 O 3, 0.10 to 0.20 percent by weight of TiO 2, 10.0 to 12.0 percent by weight of CaO, 1.0 to 2.0 percent by weight of MgO, 0.5 to 1.5 percent by weight of K 2 O, 1.5 to 2.5 percent by weight of Na 2 O, 4.5 to 7.5 percent by weight of ZnO, 6.0 to 10.0 percent by weight of BaO, and 4.0 to 6.0 percent by weight of loss on ignition; Step: applying a fully polished glaze on the surface of the green brick having the isolation glaze, the chemical composition of the fully polished glaze comprising 42 to 50 percent by weight of SiO 2, 21 to 25 percent by weight of Al 2 O 3, 0.16 to 0.46 percent by weight of Fe 2 O 3, 0.10 to 0.20 percent by weight of TiO 2, 8.5 to 10.5 percent by weight of CaO, 4.0 to 6.0 percent by weight of MgO, 0.5 to 1.5 percent by weight of K 2 O, 0.5 to 1.5 percent by weight of Na 2 O, 4.5 to 7.5 percent by weight of ZnO, 6.0 to 10.0 percent by weight of BaO, 0.5 to 2.0 percent by weight of ZrO 2, and 4.0 to 6.0 percent by weight of loss on ignition; and Step: drying, firing, and polishing the green brick having the fully polished glaze to obtain a hard wear-resistant polished glazed ceramic tile, wherein the phase composition of the fired fully polished glaze is 10 to 20 percent by weight of corundum, 20 to 30 percent by weight of hyalophane, 0.5 to 1.0 percent by weight of hematite, and 50 to 68 percent by weight of amorphous phase. Step: pressing and then drying body powder to form a green brick; Step: applying a ground coat on the surface of the green brick; Step: inkjet-printing a pattern on the surface of the green brick having the ground coat, and applying an isolation glaze, the chemical composition of the isolation glaze comprising 42 to 50 percent by weight of SiO 2, 21 to 25 percent by weight of Al 2 O 3, 0.16 to 0.46 percent by weight of Fe 2 O 3, 0.10 to 0.20 percent by weight of TiO 2, 10.0 to 12.0 percent by weight of CaO, 1.0 to 2.0 percent by weight of MgO, 0.5 to 1.5 percent by weight of K 2 O, 1.5 to 2.5 percent by weight of Na 2 O, 4.5 to 7.5 percent by weight of ZnO, 6.0 to 10.0 percent by weight of BaO, and 4.0 to 6.0 percent by weight of loss on ignition; Step: applying a fully polished glaze on the surface of the green brick having the isolation glaze, the chemical composition of the fully polished glaze comprising 42 to 50 percent by weight of SiO 2, 21 to 25 percent by weight of Al 2 O 3, 0.16 to 0.46 percent by weight of Fe 2 O 3, 0.10 to 0.20 percent by weight of TiO 2, 8.5 to 10.5 percent by weight of CaO, 4.0 to 6.0 percent by weight of MgO, 0.5 to 1.5 percent by weight of K 2 O, 0.5 to 1.5 percent by weight of Na 2 O, 4.5 to 7.5 percent by weight of ZnO, 6.0 to 10.0 percent by weight of BaO, 0.5 to 2.0 percent by weight of ZrO 2, and 4.0 to 6.0 percent by weight of loss on ignition; and Step: drying, firing, and polishing the green brick having the fully polished glaze to obtain a hard wear-resistant polished glazed ceramic tile, wherein the phase composition of the fired fully polished glaze is 10 to 20 percent by weight of corundum, 20 to 30 percent by weight of hyalophane, 0.5 to 1.0 percent by weight of hematite, and 50 to 68 percent by weight of amorphous phase.
