Abstract

The invention discloses a natural-marble-imitated ceramic tile and a preparation method thereof. The natural-marble-imitated ceramic tile is prepared from 94-97% of a green body, 1.5-2.5% of ground glaze, 0.1-1% of fancy glaze and 1.5-2.5% of surface glaze, and is prepared by the following steps of putting blank feldspar, crystal color frit, pyrophyllite, white mud and high-alumina stone into a press to be formed, drying an obtained green body, applying the ground glaze to the surface of the green body, printing fancy glaze onto the ground glaze-applied green body, applying surface glaze to the fancy glaze-applied green body, then firing the green body, and polishing a fired semi-finished product to obtain a finished product. The prepared ceramic tile has fine texture similar to that of natural marble and has the layering sense and translucency of natural stone at the same time, patterns and colors are located in the glaze, direct abrasion of patterns and colors of the ceramic tile inthe using process is avoided, the service life of the ceramic tile is prolonged, completeness and natural feeling of the patterns and colors of the tile are kept for a long time, and a more vivid effect is achieved.
