The present application provides a high-wear-resistance far-infrared ceramic polished glazed tile and preparation method therefor. The preparation method includes application of far-infrared overglaze, ink-jet printing, application of transparent far-infrared polished glaze and application of abrasion-resistant far-infrared polished glaze in sequence on a body, firing, and polishing. By adopting the far-infrared overglaze, the transparent far-infrared polished glaze and the abrasion-resistant far-infrared polished glaze in combination, the polished glaze tile can have a far-infrared function, high transparency, and high abrasion resistance.
