The invention relates to large-sized
ceramic tiles imitating jade quality and a preparation method thereof. The invention is characterized in that the forming specification of the large-sized
ceramic tiles is 1050mm*2060mm*3.0-7.0mm; fixed point fabric distribution technology is adopted on a bottom material layer to form a needed pattern, a fabric layer is arranged on the bottom material layer in the form of micro-power or common power, and the fabric layer is a semitransparent
ceramic material which accounts for 80-100% of the total fabric
layers, and the thickness of pressing ranges from 0.5 to 1.5mm. The semitransparent ceramic material comprises the following chemical components according to percentage by weight: 60-75% of SiO2, 10-20% of Al2O3, 1-4% of CaO, 0.3-3% of MgO, 5-12% of K2O+Na2O+Li2O, 0-3% of ZnO and 0-3% of P2O5. By adopting the technology of the invention, the effect similar to
underglaze color can be achieved. The pattern has strong three-dimensional sense and high
abrasive resistance, and improves the grade of the product.
