Abstract

The invention relates to an inkjet method for highly simulated marble tiles. The method comprises the following steps: 1) sintering the ceramic tile body at 850-1000°C for the first time; 2) sintering the body after step 1) Applying the underglaze, the underglaze includes 8-14% organic binder; 3) Carrying out the second sintering of the green body after applying the underglaze in the range of Tf+150°C to T1-50°C, wherein the Tf is the decomposition temperature of the organic binder, and the T1 is the first sintering temperature; 4) inkjet the green body obtained in step 3), and the boundary of the ink pigment is controlled within 150° from the corresponding texture boundary of the green body At 200 microns, the inkjet volume is 104‑158g / m 2 · mm, the m 2 is the surface area of ​​the green body, and the mm is the thickness of the bottom glaze; 5) Carry out a permeation-promoting treatment to the green body completed by inkjet. Ink jetting according to the technical solution of the invention can effectively control the penetration degree of the ink pigment, and the texture coincidence degree of the body and the bottom glaze on the longitudinal section is high, which greatly improves the three-dimensional effect and simulation degree of the ceramic tile.

Description

technical field [0001] The invention relates to an inkjet method for ceramic tiles, in particular to an inkjet method for highly simulated marble tiles. 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 application number is CN201110187245.6. The Chinese patent has obtained a ceramic infiltration glaze suitable for inkjet printing through research and development. Specifically, the technical solution is to dissolve ...
