A production process for ceramic tiles with high brightness and matt precious metal luster on the surface

Abstract

The invention provides a production process of a ceramic tile with high-light and matte precious metal gloss. The production process includes the steps of firstly, applying glaze or frit to a tile bases according to a preset pattern, wherein the preset pattern separates the tile base into at least two areas which include a high-light area and a matte area, and different kinds of glaze or frit are applied to the two areas; secondly, performing first sintering on the tile base obtained in the first step, wherein the sintering temperature is located between the complete spreading temperature of the glaze or frit applied to the high-light area and the complete spreading temperature of the glaze or frit applied to the matte area, and the complete spreading temperature of the glaze or frit applied to the high-light area is smaller than the complete spreading temperature of the glaze or frit applied to the matte area; thirdly, using precious metal gloss ink to perform ink-jet printing on at least the high-light area and the matte area in the first step; fourthly, performing secondary sintering to obtain the ceramic tile with the high-light and matte precious metal gloss, wherein the second sintering temperature is not larger than the first sintering temperature, and precious metal is gold, silver or platinum.

Description

technical field [0001] The invention relates to the production technology of architectural ceramics, in particular to a production process of ceramic tiles with high brightness and matt precious metal luster on the surface. Background technique [0002] Ceramic tiles are a common building material, mainly used for wall and floor decoration. The decorative effect of ceramic tiles with precious metal luster is magnificent, luxurious and beautiful, especially the gold, silver and electro-optic colors are more distinctive. At present, there are mainly the following ways to obtain the above metallic luster: [0003] 1. Electroplating. A layer of precious metal is electroplated on the brick surface by electrochemical means to obtain metallic luster. But in this way, the waste is serious, and the electroplating process is seriously polluted, and the coating is easy to wear and fall off, so it is basically eliminated at present. [0004] 2. Decal paper. This process uses the ba...

Problems solved by technology

[0007] The product specifications are limited, and the above processes are only suitable for small-scale products (300×300mm and below); there are many manual operations, and electroplating, decal paper and glaze ink decoration require many processes and complicated operation processes; and the scheme used There are many precious metals (gold, silver, platinum); the above factors lead to high production costs, heavy pollution, and low production capacity, and the metallic luster effect obtained by the above scheme is single, that is, bright or matte, and it is impossible to combine the two

Therefore, ceramic tile products with metallic luster are all decorated with a glossy effect at present, and it is impossible to obtain a matte and high-gloss effect on the brick surface. The matte effect is difficult to obtain, and even if the matte brick surface is obtained It will not be stain-resistant due to more pinholes, so the product mostly has a high-gloss effect
