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] This embodiment provides a process for producing a ceramic tile with high gloss and matte metallic finish on the surface, which includes the following steps:

[0025] Step 1: Use ceramics to produce general-purpose bricks. In this embodiment, the ceramic tile production formula with a well-known original formula of the brick blank is selected, which is composed of clay, feldspar, quartz (sand) and other well-known raw materials, and is stamped from powder made by ball milling to remove iron and spray granulation. Since it is a well-known technology, it will not be repeated here, and those skilled in the art can refer to well-known raw material standards and make appropriate adjustments according to the firing process. For porcelain products, the water absorption rate E is less than or equal to 0.5%, and for stoneware products, the water absorption rate E is 3% to 6%.

[0026] Step 2: Apply the base glaze: On the selected bricks, use a silk screen to print two layers of glaz...

Embodiment 2

[0033] In this embodiment, the glaze applied on the matte area contains boron element. The use of boron-containing frit particles can reduce pinhole defects in the matte area of ​​the final product and improve the product's stain resistance. This can be compared by ink test. The matte area has a higher firing temperature of the glaze than the high-gloss area, and contains more refractory components (such as alumina, etc.) in the composition, so it is both the first firing and the second firing. Pinhole defects are prone to occur, and these defects will affect the product's antifouling performance. The introduction of boron can make the glaze layer better exhaust 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 Therefore, the glaze applied in 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 applying the glaze is not included. The rest of the process is the same as in Example 1. The appearance of the product is basically the same, but the product warpage is serious, so the product degradation caused by defects is up to 25%. Only 7%. Here, because different areas are formed by applying different glazes or frit on the surface of the brick, the surface tension problem will adversely affect the flatness of the brick during the first firing. In the prior art, the application of glaze is layered application, that is, one layer is applied and then another layer is applied. Even if there is an overlapped part in it, it is partially overlapped. In addition to this method in the present invention, Applying different glazes to different areas on the tile surface will cause greater stress. Therefore, applying multiple layers of glaze on the surface of the brick as in Example 1 will alleviate this defect.

[0039] In addition, in order to ...

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 building ceramics, in particular to a production process of a ceramic tile with high gloss and matte noble 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 golden, silver and electro-optical colors are more distinctive. At present, there are several ways to obtain the above metallic luster: [0003] 1. Electroplating. Electroplating a layer of precious metal on the brick surface by electrochemical method to obtain metallic luster. However, this method has serious waste and serious pollution in the electroplating process, and the plating layer is easy to wear and fall off, which is basically eliminated. [0004] 2. Decal paper. This process uses a baking process to mix precious metal pig...
