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

Embodiment 1

[0024] The present embodiment provides, a kind of surface has the production technology of the luster ceramic tile of bright and matte metallic luster, and it comprises the steps:

[0025] Step 1: Choose ceramics to produce general-purpose adobes. The adobe selected in this embodiment has a known ceramic brick production formula, which is composed of clay, feldspar, quartz (sand) and other known raw materials, and is stamped from powder made by spray granulation after iron removal by ball milling. Since it is a known technology, it will not be described in detail here, and those skilled in the art can refer to known raw material standards and make appropriate adjustments according to the firing process. For porcelain products, the water absorption rate E≤0.5%, for stoneware products, the water absorption rate E is 3%~6%.

[0026] Step 2: Applying the bottom glaze: on the selected brick, use a silk screen to print two layers of glaze. There are two types of glazes, one is mat...

Embodiment 2

[0033]In this example, boron is included in the glaze applied to the matte areas. The use of boron-containing frit particles can reduce pinhole defects in matte areas of the final product and improve product stain resistance. This can be compared with the inkblot test. Because the firing temperature of the glaze used in the matte area is higher than that of the high-gloss area, the components contain more refractory components (such as alumina, etc.), so the first firing and the second firing are equal. It is easy to produce pinhole defects, which will affect the stain resistance of the product. The introduction of boron element can make the glaze layer exhaust better in the first firing, and in the second firing, it will also better combine with the precious metal elements in the ink to obtain a smooth surface , so the glaze applied on the matte area contains boron element, which greatly improves the stain resistance of the product. In addition, because boron has a certain...

Embodiment 3

[0038] In this embodiment, the step of distributing the bottom glaze is not included, and the rest of the process is the same as in embodiment 1. The appearance effect of the product is basically the same, but the product is warped and deformed seriously, so the product degradation caused by defects reaches 25%, while the product in embodiment 1 Only 7%. Here, because different areas are formed by distributing different glazes or frits on the surface of the adobe, the problem of surface tension during the first firing will have a bad influence on the flatness of the brick. In the prior art, the application of glaze is layered application, that is, application of one layer and then application of another layer, even if there are overlapped parts in it, they are partially overlapped, but in the present invention, except for this method, there will be Different glazes are applied to different areas of the brick surface, which creates greater stress. Therefore, this defect can be...

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...
