Abstract

The invention belongs to the field of ceramics, and discloses ceramic digital ink with a matte carving effect and application thereof. The digital ink with the matte carving effect is composed of powder, a solvent and an auxiliary, and the powder is composed of albite, wollastonite, limestone, calcined zinc oxide, quartz, corundum and high-calcium zinc-containing frit. The ceramic digital ink of some examples is particularly suitable for preparing digital mold tiles, the mold effect is good, the mold depth can reach 0.1-0.3 mm, lines are clear, particularly turning positions are also clear, and the obvious matte carving effect is achieved. The ceramic digital ink of some examples is simple in preparation method, low in production cost and suitable for large-scale production.

Description

technical field [0001] The invention relates to new materials for ceramics, in particular to a ceramic digital ink with matte engraving effect and its application. Background technique [0002] With the popularity of rock slabs, the application of ceramic digital glazes has also been further developed. The previous ceramic production line only needed one inkjet machine to meet the requirements, but now with the maturity of digital glazes, many processes are processed by three inkjet machines. The machines are used in series to completely replace the water glaze, thus realizing the production of an anhydrous glaze line. [0003] With the realization of the waterless glaze line concept, many new processes have also been realized. However, it is still extremely difficult to achieve a micro-stereoscopic ceramic effect by inkjet printing. [0004] CN112358326A discloses a preparation method of ceramic tiles with a matte deep engraving effect and ceramic tiles, using the princip...
