Description

TECHNICAL FIELD

[0001] The present application relates to a porcelain tile with a relief composite brilliant color dry particle decoration effect and a preparation method thereof, and belongs to the technical field of ceramic tile production and manufacturing. BACKGROUND

[0002] According to market research data, the global high-end building decoration material market maintains an average annual growth rate of 6%-8%, among which the demand for high-end products such as stone-like ceramic tiles and artistic ceramic tiles has increased significantly. Consumers' demand for ceramic tile products has shifted from single functionality to decoration, personalization and environmental protection, especially the demand for ceramic tiles with high-end decoration effects such as natural stone and wood is strong. Natural stone has problems such as resource scarcity, high mining cost, large color difference and radioactivity, while ceramic tiles developed through micro-mold, multi-color dry particles and real stone replica glaze can highly restore the texture and quality of natural stone, becoming an ideal substitute for natural stone.

[0003] Chinese patent CN112811939A discloses a manufacturing method of a porcelain plate with a sparkling grain effect. The method uses a paving device or a carved roller type partition device to apply a mixed dry particle containing sparkling grains and transparent dry particles to form a sparkling grain layer, and then applies a transparent glaze layer on the sparkling grain layer to obtain a porcelain plate with a sparkling grain effect. The amount of sparkling grains used in the method is large, and the amount of polishing glaze also needs to be increased to cover the sparkling grains, which is difficult to control and has high cost. Moreover, the surface effect is single.

[0004] Chinese patent CN117510069A discloses a ceramic rock plate with a concave-convex effect and a preparation method. The method includes preparing a green body, applying a base glaze on the green body, pre-spraying a sunken ink, spraying a bright light mold glaze, spraying a sunken ink again using an ink jet machine, firing in a kiln, slowly cooling and keeping warm, and finally slowly cooling to room temperature. The functional ink containing rare metal inorganic materials is more stable, has rich color system, uniform diffusion gradient, stronger level sense, and more three-dimensional effect. Moreover, unlike the method of forming a three-dimensional mold texture by physically pushing away, the ceramic surface with deep concave-convex texture has deep concave-convex texture, clearer pattern, high hardness, and strong stain resistance and acid resistance. However, the process is relatively complex and belongs to overglaze decoration, and the pattern may be easily worn off after long-term use.

[0005] Compared with antique tiles and polished glaze tiles, the brilliant color dry particle composite decoration effect real stone glaze porcelain tile has good level sense of the surface pattern, clear texture, strong texture feeling, and warm and smooth glaze surface. Therefore, the brilliant color dry particle composite decoration effect real stone glaze porcelain tile product, which perfectly combines multi-color dry particles with designed pattern texture and functional ink, will have certain market advantage in market competition.

DETAILED DESCRIPTION

[0021] The present application is further illustrated by the following embodiments, which should be understood as merely illustrative of the present application, but not limiting the present application.

[0022] The present application is developed by combining a skin glaze, a relief ink, and multi-color dry granules with a design pattern. The process is as follows: a base glaze is applied on a dried body, then a skin glaze is applied, a design pattern is printed by inkjet, a relief ink is printed according to the pattern texture, a protective glaze is sprayed, the relief ink can react with the skin glaze to form a concave-convex sunken effect, and can have a certain physical reaction with the protective glaze, and can better reflect the concave-convex effect, and the protective glaze can also protect the pattern from being worn after being sprayed, then multi-color dry granules are applied on the body according to the pattern texture, and the body is fired in a kiln.

[0023] The conventional water-oil repulsion mainly produces a sunken effect, and is mainly in a line state or a dot state, and cannot realize a large-area sunken effect. The relief effect of the present application produces a large-area sunken effect on the tile surface according to the pattern, and then a skin glaze is applied on the upper layer, which is mainly beneficial to the relief ink to erode the skin glaze from top to bottom to produce a concave-convex effect. Since the amount of the relief ink used is large and the area is large, if the relief ink is printed by inkjet between the base glaze and the skin glaze, problems such as shrinkage of the glaze and pinholes are likely to occur, and the dark pattern has poor transparency due to the large amount of the skin glaze, and therefore the glazing process sequence according to the present application is more beneficial to the product decorative effect and improves the product quality.

[0024] The following exemplary describes the preparation method of the porcelain tile with a relief composite brilliant dry granule decorative effect.

[0066] Comparative Example 2

[0067] The method for preparing ceramic tiles includes:

[0068] Step 1. The body powder is pressed into a body, and the body is dried.

[0070] Step 3. A normal ink pattern is jet-printed on the surface of the body after the base glaze is applied.

[0071] Step 4. A relief ink pattern is jet-printed on the surface of the body after the normal ink pattern is jet-printed.

[0072] Step 5. A skin glaze is applied to the surface of the body after the relief ink pattern is jet-printed. The mineral composition, chemical composition, and glazing parameters of the skin glaze are consistent with those of Example 1.

[0073] Step 6. A protective glaze is applied to the surface of the body after the skin glaze is applied. The mineral composition, chemical composition, and glazing parameters of the protective glaze are consistent with those of Example 1.

[0074] Step 7. The body after the protective glaze is applied is dried.

[0075] Step 8. Inkjet printing glue pattern on the surface of the dried body, and positioning and applying the multi-color dry granules according to the multi-color dry granule texture. The mineral composition, chemical composition, and glazing parameters of the multi-color dry granules are consistent with those of Example 1. The dry granule recovery device is used to suck away the excess dry granules.

[0076] Step 9. The body with the positioned and applied multi-color dry granules is fired in a kiln. The firing temperature is 1210°C, and the firing time is 40 minutes.

[0077] The relief effect of the comparative example is poor, and due to the high ink amount, the sprayed skin glaze layer is difficult to dry, resulting in shrinkage, glaze pits, and pinholes, and the pattern definition is poor.
