[0032] S1: preparing ceramic tile green body;

[0033] Specifically, the green body of the ceramic tile is obtained after milling, distributing, pressing, and drying; the formula of the green body of the ceramic tile is a porcelain brick formula, that is, the water absorption rate is ≤0.5% after firing.

[0034] S2: applying a primer on the surface of the green ceramic tile;

[0035] Specifically, the primer can be applied on the surface of the ceramic body by means of pouring glaze, spraying glaze, dipping glaze, etc., but not limited thereto. Preferably, the underglaze is applied by bell jar glazing.

[0036] Specifically, the chemical composition of the bottom glaze is SiO 2 53.5~60%, Al 2 o 3 13~15%, Fe 2 o 3 0.2~0.7%, TiO 2 0.3~0.5%CaO 1~3%, MgO 1~3%, K 2 O 5~8%, Na 2 O 2-4%, ZnO 1.5-2.5%, BaO 8-11%, LOI 3.5-8%. ...

Embodiment 1

[0067] This embodiment provides a kind of colorful effect ceramic tile, and its preparation method is as follows:

[0068] (1) preparing a ceramic green body;

[0069] The ceramic body adopts conventional porcelain brick body;

[0070] (2) applying a bottom glaze on the surface of the ceramic body;

[0071] Among them, the chemical composition of the bottom glaze is: SiO 2 54.18%, Al 2 o 3 13.85%, Fe 2 o 3 0.26%, TiO 2 0.47%, CaO 1.45%, MgO 2.28%, K 2 O 7.54%, Na 2 O 3.36%, ZnO 1.89%, BaO 10.55%, LOI 4.17%; the bottom glaze is dark gray after firing; the specific gravity of the bottom glaze is 1.86g / mL, the flow rate is 45s, and the glaze amount is 360g / m 2 ;

[0072] (3) applying dry glaze on the surface of the ceramic body;

[0073] Among them, the formula of the dry granule glaze is: 8 parts of superfine dry granules, 46 parts of glue, and 46 parts of transparent glaze;

[0074] The chemical composition of ultrafine dry particles is: SiO 2 30.54%, Al 2 o ...

Embodiment 2

[0083] This embodiment provides a kind of colorful effect ceramic tile, and its preparation method is as follows:

[0084] (1) preparing a ceramic green body;

[0085] The ceramic body adopts conventional porcelain brick body;

[0086] (2) applying a bottom glaze on the surface of the ceramic body;

[0087] Among them, the chemical composition of the bottom glaze is: SiO 2 56.08%, Al 2 o 3 13.76%, Fe 2 o 3 0.31%, TiO 2 0.49%, CaO 2.17%, MgO 1.94%, K 2 O 6.12%, Na 2 O 2.41%, ZnO 1.69%, BaO 10.75%, LOI 4.28%; the bottom glaze is dark gray after firing; the specific gravity of the bottom glaze is 1.84g / mL, the flow rate is 43s, and the glaze amount is 370g / m 2 .

[0088] (3) Carry out inkjet printing decoration on the surface of the ceramic body;

[0089] (4) applying dry granular glaze on the surface of the ceramic body;

[0090] Among them, the formula of the dry granule glaze is: 12 parts of superfine dry granules, 50 parts of glue, and 38 parts of transparent g...

Abstract

The invention discloses a method for preparing ceramic tiles with colorful effects, which comprises: preparing a green body, applying bottom glaze, applying dry granular glaze, firing, and sequentially using 200-500-mesh nylon diamond grinding disc, 600-800-mesh resin Grinding discs and 1200 mesh-2000 mesh resin grinding discs are polished to obtain finished ceramic tiles with colorful effects. Wherein, the dry granule glaze includes superfine dry granule and transparent glaze; the particle size of the superfine dry granule is ≤250 mesh. The invention greatly reduces the particle size of the dry particles in the dry particle glaze, weakens the concave-convex effect caused by the dry particles, and makes the brick surface difficult to hide dirt. At the same time, the ultrafine dry particles of the present invention cooperate with the transparent glaze to form a dry glaze; wherein, the transparent glaze melts after firing; and the ultrafine dry particles do not melt after firing due to the high aluminum content, so that the ultrafine dry particles wrap In the glass body formed by the glaze slurry, the brick surface has a dazzling metal aperture under the light, and the decorative effect is greatly improved.

Description

technical field [0001] The invention relates to the technical field of ceramic tiles, in particular to a colorful effect ceramic tile and a preparation method thereof. Background technique [0002] With the development of ceramic tile technology, people's requirements for the functional and decorative performance of ceramic tiles are increasing day by day. As far as functionality is concerned, anti-slip and stain resistance are the main directions of concern at present. For decoration, the luster and pattern of ceramic tiles are the main directions of attention. In this context, "dry granules", as a new means of decoration and functionalization, are gradually being applied in the production process of ceramic tiles. [0003] Dry granules are essentially a special kind of frit; dry granules have been applied many times during the development of ceramic tiles. For example, at the beginning of the 20th century, the microcrystalline brick introduced by the ceramic industry wa...
