Description

Technical Field

[0001] The invention relates to the technical field of ceramic tiles, and in particular to a ceramic tile with metallic luster and a preparation method thereof. Background Art

[0002] In the field of modern home decoration, with the continuous changes in people's aesthetic concepts and the growing personalized needs, the decoration style shows a diversified development trend. In this process, metal plates, with their natural and unique texture and strong glossiness, have become a key element to improve the grade and quality of home decoration. The use of metal plates can not only make the home environment more modern and fashionable, but also create a unique artistic atmosphere, which is deeply loved by consumers.

[0003] However, metal plates also face some unavoidable problems during use. As metal plates are constantly in contact with oxygen in the air, a series of chemical reactions will occur over time, the most common of which is oxygen absorption corrosion. This phenomenon will not only seriously affect the appearance of the metal plate, causing it to lose its original luster and texture, but may also further affect its service life and even seriously affect its anti-fouling effect.

[0004] In summary, after extensive searching by the applicant, it is found that at least the existing ceramic tiles in this field have insufficient gloss and three-dimensional effect of the positive and negative surfaces, lack delicate and beautiful metallic glare, and have poor anti-fouling performance. Therefore, it is necessary to develop or improve a ceramic tile with metallic luster and a preparation method thereof. Summary of the invention

Specifically, since tantalum nitride has excellent chemical stability and thermal conductivity, beryllium zirconate has excellent corrosion resistance and good thermal conductivity, niobium nitride has excellent corrosion resistance, thermal stability and thermal conductivity, and tetracarboxyphthalocyanine vanadium has excellent chemical stability and heat resistance, α-hydroxy-ω-carboxy polyethylene glycol has good stability and abundant reactive groups, and N-benzanilide-4,4'-dicarboxylic acid has multiple functional groups, the metal glaze prepared by gold dry particles containing tantalum nitride, beryllium zirconate and tetracarboxyphthalocyanine vanadium, platinum dry particles containing niobium nitride, beryllium zirconate and tetracarboxyphthalocyanine vanadium, and a suspension containing α-hydroxy-ω-carboxy polyethylene glycol and N-benzanilide-4,4'-dicarboxylic acid can make the final ceramic tile have high-gloss, delicate and beautiful metallic glare, and have a three-dimensional effect of yin and yang surfaces, and its anti-fouling level is as high as level 5.
