Description

Technical Field

[0001] This invention relates to the field of building material preparation, and more specifically, to a ceramic tile with a gold decorative effect and its preparation method. Background Technology

[0002] In the field of modern home decoration, with the continuous changes in people's aesthetic concepts and the increasing demand for personalization, decoration styles are showing a diversified development trend. Tile products are also becoming more upscale, personalized, and artistic. To this end, those skilled in the art have developed tiles with metallic effects. Glazed tiles with metallic effects can present a certain metallic luster and have an elegant and noble decorative effect, especially tiles with gold decorative effects.

[0003] Traditional gold-effect ceramic tiles or products are generally made using the following methods to achieve a gold effect: gold decorative lines or blocks are applied to the surface of the tile using a pigment prepared by mixing real gold powder with a solvent, which is then applied to the tile surface and fired. However, this method suffers from poor color reproduction. Screen printing followed by firing is another method, but the gold paste used in screen printing is expensive, resulting in high production costs. Decal paper is another method, where gold ink is pre-made into decals, which are then applied to the tile before firing. However, this method often results in a dull visual appearance and an unsatisfactory gold effect. Electroplating also imparts a gold effect to the ceramic surface, but this process is highly polluting and difficult to mass-produce.

[0004] For example, Chinese patent application number 201220233208.4 discloses a cermet tile, in which a metal layer is partially or completely covered on the surface of the ceramic layer. This metal layer is formed by sintering nano- or ultrafine metal particles, and different colors and glosses are used in different areas of the ceramic or glaze surface. This method produces a gold glaze effect by covering or bonding a metal layer, but the cermet tiles prepared by this method are not firmly bonded and the metal layer is easily worn away and peeled off. Furthermore, existing technologies also use cheaper materials that can produce a gold effect in the preparation of ceramic tiles. However, with long-term use, the decorative effect of these materials often fails to meet consumer demands, and over time, glazed tiles easily become dirty and fade, causing the ceramic tile products to lose their original aesthetic appeal and affecting their normal use. Summary of the Invention

[0005] Therefore, in order to solve the problem that the gold decorative effect in the existing technology is not good and easily loses its original aesthetic appeal, the present invention provides a gold-decorated ceramic tile and its preparation method, the specific technical solution of which is as follows:

[0007] The bright material comprises the following raw materials in parts by weight:

[0008] 13-15 parts of high-whiteness kaolin, 5-9 parts of glass powder, 8-12 parts of zirconium silicate, 11-13 parts of sodium alkylbenzene sulfonate, and 1-3 parts of degumming agent;

[0012] Furthermore, the degumming agent is at least one of sodium tripolyphosphate, sodium hexametaphosphate, sodium humate, and sodium polyacrylate.

[0013] Furthermore, the preparation method of the bright material is as follows:

[0014] High-whiteness kaolin, glass powder, and zirconium silicate are mixed to obtain mixture A;

[0015] The mixture A is added to a ball mill and milled at a speed of 100 r / min to 500 r / min for 20 min to 45 min. Then, sodium alkylbenzene sulfonate and a desiccant are added, and the mixture is stirred for 15 min to 30 min. After aging, a glossy material is obtained.

[0016] Furthermore, the gold decorative powder is at least one of gold powder and copper-aluminum alloy powder.

[0017] Furthermore, the base frit comprises the following components by mass percentage: SiO2 20%–35%, Al2O3 5%–7%, CaO 12%–18%, MgO 10%–15%, MnO 13%–20%, Fe2O3 0.1%–0.2%, ZnO 10%–15%, and TiO2 7%–15%.

[0018] Furthermore, the method for preparing the suspending agent is as follows:

[0019] By weight, 7-15 parts of waterborne polyurethane resin and 5-9 parts of emulsifier are added to 35-48 parts of water and stirred evenly. Then, 10-12 parts of α-hydroxy-ω-carboxylated polyethylene glycol, 9-12 parts of 2'-(2'-hydroxy-3'-tert-butyl-5'-methylphenyl)-5-chlorobenzotriazole and 1-7 parts of tris(2,4-di-tert-butylphenyl) phosphite are added and stirred at 200 r / min to 500 r / min for 15 min to 20 min to obtain a suspension.

[0020] Furthermore, the dispersant is at least one selected from nonylphenol polyoxyethylene ether, polyethylene glycol, polyvinyl alcohol, vinyltrimethylsilane, and isocyanate-based trimethoxysilane.

[0021] Furthermore, the preparation method of the gold decorative effect material is as follows:

[0022] Mix the gold decorative powder, suspending agent, dispersing agent and binder evenly to obtain mixture B;

[0023] Add the base frit to a ball mill and ball mill it at a speed of 100 r / min to 500 r / min for 15 min to 30 min. Then add the mixture B and continue to stir until homogeneous to obtain the gold decorative effect material.

[0024] In addition, the present invention also provides a method for preparing ceramic tiles with a gold decorative effect, the method comprising the following steps:

[0025] Using conventional processes, a base glaze is applied to the brick blank to form a base glaze layer; then ink is sprayed onto the base glaze layer to form an inkjet layer; finally, a composite glaze is applied to the surface of the inkjet layer, and the brick is fired at 1150℃~1200℃ to form a composite glaze layer.

[0026] Through fine carving, grooves are finely carved into the composite glaze layer. Then, a glossy material is coated into the grooves and dried. After drying, a polishing glaze is applied and dried to form a polishing glaze layer. The thickness of the polishing glaze is less than the depth of the grooves. Then, the brick surface is cut and polished.

[0027] By using linear three-dimensional scanning, the grooves are filled with gold decorative material. After filling, the material is transferred to a kiln and fired at 800℃~1000℃. After polishing and edge grinding, a gold decorative tile is obtained.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] 1. This invention optimizes the composition of the glossy material, resulting in excellent stability and rheological properties, which can exert a superior brightening effect. It can work synergistically with gold decorative materials, making it shine brightly under light, with a highly decorative effect reminiscent of gold, and offering excellent aesthetic appeal and user experience.

[0030] 2. This invention optimizes the composition of the gold decorative effect material. The synergistic effect of the specially formulated suspending agent and dispersant not only increases the dispersibility of the gold decorative powder and its environmental durability, but also, combined with the action of the adhesive, increases the adhesion between the gold decorative material and the polished glaze layer. Furthermore, by adding a base frit, the gold decorative powder is evenly distributed in the base frit during subsequent firing, forming a delicate and excellent gold iridescent tile appearance. In addition, the use of irregular gold decorative materials with different mesh sizes can refract metallic light from different angles, achieving an even better gold decorative effect.

[0031] 3. By optimizing the composition of the polishing glaze, this invention can increase its bonding with gold decorative materials, and also has better corrosion resistance and stain resistance. The brick surface is smooth and delicate, with excellent ornamental and artistic value. Detailed Implementation

[0119] The difference between Comparative Example 10 and Example 3 is that the chemical composition ratio of the polishing glaze in Comparative Example 10 is different, while the rest is the same as in Example 3. The preparation method of the polishing glaze in Comparative Example 3 is as follows: 35 parts by weight of silicon oxide, 1 part of aluminum oxide, 1 part of iron oxide, 12 parts of calcium oxide, 5 parts of magnesium oxide, 5 parts of potassium oxide, 9 parts of sodium oxide, 5 parts of zinc oxide, 9 parts of sodium carbonate, 1 part of barium oxide, and 1 part of strontium oxide are mixed to obtain mixture C. After wet ball milling, a density of 3.86 g / cm³ is obtained. 3 Polishing glaze, ready for use.

[0120] The appearance quality of the ceramic tile samples prepared in Examples 1-3 and the comparative ceramic tile samples prepared in Comparative Examples 1-10 was observed by performing appearance tests, and the results are recorded in Table 1 below.

[0124] In addition, the ceramic tile samples prepared in Examples 1 to 3 and the comparative ceramic tile samples prepared in Comparative Examples 1 to 10 were subjected to performance tests. The gloss was tested in accordance with GB / T15614-2015, the corrosion resistance was tested in accordance with GB / T4100.7-2006, and the stain resistance was tested in accordance with GB / T4100-2015. The results are shown in Table 2 below.

[0126]

[0127] Analysis of the data in Tables 1 and 2 shows that this invention, by optimizing the composition of the glossy material, the gold decorative effect material, and the polishing glaze, can produce ceramic tiles with significantly improved gloss, wear resistance, and stain resistance, as well as a gold decorative effect. Specifically, through precise carving and positioning, the tile surface is endowed with excellent artistic appeal. The glossy material achieves a certain mirror effect, and the synergistic effect of the glossy material and the gold decorative effect material results in an excellent metallic feel that directly reflects light, shining even more brilliantly under different lighting conditions, thus enhancing the gold decorative effect. Furthermore, the design of the polishing glaze ensures good integration of raw materials during polishing, with no gold decorative effect material falling off during polishing, demonstrating excellent adhesion and preventing surface defects. The overall surface is smooth and delicate, resulting in an excellent decorative effect. The difference between Comparative Examples 1-3 and Example 3 lies in the composition of the glossy material. The difference between Comparative Example 4 and Example 3 is that Comparative Example 4 did not add glossy material. Although the glossy material does not affect the polishing glaze and can produce smooth and delicate ceramic tiles, it does affect the metallic refraction effect of the gold decorative material, thus affecting the metallic sheen and resulting in a poorer gold decorative effect. The difference between Comparative Example 5 and Example 3 is that no silicone-based waterborne polyurethane (adhesive) was added to the gold decorative material in Comparative Example 5. During the subsequent polishing process, the gold decorative material experienced slight peeling, and glaze defects increased, resulting in a poorer gold decorative effect compared to Example 3. Furthermore, the corrosion resistance and stain resistance of the glaze were also worse than in Example 3. This indicates that adding an appropriate amount of silicone-based waterborne polyurethane (adhesive) during the preparation of the gold decorative material in this application can significantly improve the adhesion of the gold decorative material, reduce the occurrence of glaze defects, and indirectly improve corrosion resistance and stain resistance. The difference between Comparative Example 6 and Example 3 is that no basic frit was added in Comparative Example 6, resulting in a weaker metallic sheen on the tile's appearance. The gloss, corrosion resistance, and stain resistance were all worse than in Example 3. This indicates that adding a preferred basic frit during the preparation of the gold decorative material in this application can reduce tile surface defects that occur during the subsequent polishing process. The difference between Comparative Example 7 and Example 3 is that no suspending agent was added in Comparative Example 7, leading to poor dispersion of the gold decorative material, which also affected the gloss and surface effect of the tile. The difference between Comparative Example 8 and Example 3 lies in the raw materials used to prepare the suspending agent. The 2'-(2'-hydroxy-3'-tert-butyl-5'-methylphenyl)-5-chlorobenzotriazole and 7 parts of tris(2,4-di-tert-butylphenyl) phosphite added to the suspending agent provide UV protection and antioxidant effects, leading to a decrease in the environmental resistance of the gold decorative material in Comparative Example 8 and affecting its performance, including reduced stain resistance. The difference between Comparative Example 9 and Example 3 lies in the use of flake-shaped gold decorative material with a uniform 20-mesh particle size. However, the refractive index is poor, resulting in a decrease in the gloss of the brick surface. This indicates that different gold decorative powders affect the gold decorative effect, and the preferred gold decorative powder in this application can improve the gold decorative effect.The difference between Comparative Example 10 and Example 3 lies in the composition of the polishing glaze in Comparative Example 10. This difference leads to surface defects, such as pinholes, in the subsequent polishing process, affecting the gold decorative effect. Furthermore, due to these surface defects, the stain resistance is significantly worse than in Example 3. In summary, this application, through the optimization of glossy materials, gold decorative materials, and polishing glaze, achieves a synergistic effect, enabling the preparation of decorative ceramic tiles with a strong gold effect, excellent aesthetic appeal, and superior user experience, and allowing for large-scale mass production. Additionally, Example 2, which uses irregular copper-aluminum alloy powder for gold decorative powder, also achieves a gold decorative effect. Moreover, during the preparation process, the copper-aluminum alloy powder does not oxidize and turn black or discolor, indicating a lower cost of raw materials. This demonstrates that the optimized composition of this application has broader practicality and applicability, meeting market demands.
