Problems solved by technology

[0002] The surface coloring of the existing ceramic body is carried out by glazing, that is, a glaze layer is applied on the surface of the ceramic body. The glaze layer is usually thicker and the amount of glaze applied is relatively large. Taking a ceramic tile with a size of 45×95mm as an example, it requires 4.0 ~6.0 g / piece of glaze, so there are obvious glaze traces on the surface of the product, the uneven contour of the mold surface is not clear, the effect of imitating stone is poor, the color of the glaze is relatively limited, the process is more complicated, and the production cost is high

Embodiment 1

[0043] Such as figure 1 Shown, the invention provides a kind of method for coloring the surface of ceramic body, the method comprises the steps:

[0044] 1. Preparation of ceramic body

[0045] Configure the green body raw materials, where K 2 O and Na 2 The content of O is controlled at 4.0% to 6.0% of the weight percentage of the total ceramic body raw material; K 2 O: Na 2 O=1:0.8~1:2; the CaO content is controlled below 1.5% by weight of the total ceramic body raw materials; the MgO content is controlled below 1.5% by weight of the total ceramic body raw materials.

[0046] Perform ball milling and pulping on the configured green body raw materials;

[0047] To test the mud;

[0048] Spray and granulate the slurry;

[0049] Detect the powder formed after granulation;

[0050] The qualified powder is pressed into a ceramic green body.

[0051] 2. Atomize and spray the coloring agent on the surface of the ceramic body. The raw materials of the coloring agent are tap...

Abstract

The invention discloses a method for coloring the surface of a ceramic body and a ceramic colorant. The method comprises the following steps of: (1) spraying the colorant on the surface of the ceramic body, wherein the raw materials of the colorant comprise water, a chemical material, a ceramic pigment and a suspension stabilizer, and the chemical material is one or a combination of a low-temperature bright flux, a high-temperature non-luminous material and an opacifier; (2) drying the ceramic body sprayed with the colorant; and (3) burning the dried ceramic body at a high temperature to obtain a product, wherein the raw materials of the colorant comprise water, a chemical material, a ceramic colorant and a suspension stabilizer. The used colorant disclosed by the invention mainly contains water, also contains a little of chemical material and ceramic pigment, and is sprayed on the surface of the ceramic body; the spraying amount is less; and the cost is very low and the process is very simple compared with the existing glazing method.. The colorant is sprayed on the surface of the ceramic body; the product can completely keep the modular surface effect of the ceramic body before being sprayed with the colorant; and concave and convex outlines of the modular surface are clearer and sharper, and the effect of imitating stone is vivid.
