Problems solved by technology

Although this method improves the fidelity of the texture to a certain extent through the multi-tube fabric, but because it does not rationally optimize the heating process parameters, the resulting blank has obvious pigment penetration and high distortion of the longitudinal section texture

Abstract

The invention provides a preparation method of a high-fidelity ceramic tile blank body. The preparation method is characterized by comprising the following steps: 1) respectively putting mud and powder in a ball mill for ball milling and performing spray drying to obtain hard powder; 2) paving mud in a grinding tool, then press-molding and once-firing at a temperature of 850-1000 DEG C; 3) applying the powder onto a mud blank body fired in the step 2) to form a powder layer with texture fine lines and performing HIP treatment; 4) performing secondary firing on the blank body obtained in the step 3), wherein the secondary firing temperature is lower than the primary firing temperature; 5) repeating the steps 2)-4) at least once; 6) firing the finally-obtained blank body at a temperature of1200-1300 DEG C. The blank body obtained by the preparation method provided by the invention has strong stereoscopic sensation on a longitudinal section while having excellent fidelity.

Description

technical field [0001] The invention relates to a method for preparing a ceramic tile body, in particular to a method for preparing a ceramic tile body with a high simulation degree. Background technique [0002] Natural marble has always been sought after by people as a stone decoration material because of its noble and elegant appearance. However, as a non-renewable resource, natural marble has higher and higher mining and production costs. In order to meet people's growing demand for natural marble and reasonably control production costs , There are more and more artificial marbles on the market. However, due to poor technology, the imitation degree and three-dimensional effect of the prepared artificial marble are not ideal, which greatly affects the fidelity of the marble. [0003] The Chinese invention patent with the patent application number CN201810587557.8 discloses a method for manufacturing ceramic tiles with a three-dimensional decorative effect, which includes...
