Description

Technical Field

[0001] The invention relates to the field of building material preparation, in particular to a ceramic tile with a gold decorative effect and a preparation method thereof. Background Art

[0002] In the field of modern home decoration, with the continuous changes in people's aesthetic concepts and the growing personalized needs, the decoration style shows a diversified development trend, and ceramic tile products are also being upgraded, personalized and artistic. For this reason, technical personnel in this field have developed ceramic tiles with metallic effects. Glazed tiles with metallic effects can present a certain metallic luster, and the decorative effect is elegant and noble, especially ceramic tiles with gold decorative effects.

[0003] Traditional gold effect tiles or porcelain products are generally given a certain gold effect by the following methods: by drawing gold decorative lines or color blocks on the surface of the tile, the colorant is prepared by mixing real gold powder with a solvent, and then applied to the surface of the tile blank and fired, but there is a problem of poor color; by silk screen printing and then firing, but the gold paste used in the silk screen printing method is expensive and the preparation cost is high; the decal paper method, that is, using gold water to pre-make decals, and the tile products are fired after decals, but there is a problem of dull vision and poor gold effect; the electroplating process gives the ceramic surface a certain gold effect, but the electroplating process has serious pollution and is difficult to mass produce.

[0004] For example, the Chinese patent application number 201220233208.4 discloses a metal ceramic tile, in which a metal layer is partially or completely covered on the surface of the ceramic layer of the metal ceramic tile, and the metal layer is formed by sintering nano-scale or ultra-fine metal particles, and different areas of the ceramic layer or glaze layer surface use metal layers of different colors and luster. This method uses a method of covering a metal layer or bonding a metal layer to produce the effect of colored gold glaze, but the metal ceramic tile prepared by this method is not firmly bonded, and the metal layer is easily worn and peeled off. In addition, the prior art also uses lower-priced materials that can produce a gold effect in the preparation of ceramic tiles, but such materials are used for a long time, and their decorative effects often fail to meet the needs of consumers, and as time goes on, glazed tiles are prone to dirtiness and fading, making the ceramic tile products lose their original ornamental value and affecting their normal use.

[0118] Comparative Example 10:

[0122]

[0123]

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

[0125] Table 2: Performance test results

[0126]

[0127] According to the data analysis of Table 1 and Table 2, the present invention can obtain tiles with significant gloss, wear resistance and antifouling performance and gold decorative effect by optimizing the composition of bright material, gold decorative effect material and polishing glaze. Among them, through fine carving and positioning, the surface of the tile is given excellent artistic appreciation, and the bright material achieves a certain mirror effect. Under the synergistic effect of the bright material and the gold decorative effect material, the excellent metal feel can directly reflect light, especially more shining under different light, and the gold decorative effect is more excellent. In addition, the design of the polishing glaze has better fusion of the raw materials during the polishing process, and no gold decorative effect material falls off during polishing. It has excellent adhesion, and thus no defects on the brick surface occur. The overall surface is delicate and smooth, and the decorative effect is excellent. The difference between Comparative Examples 1 to 3 and Example 3 is that the composition of the bright material is different. The difference between Comparative Example 4 and Example 3 is that no bright material is added in Comparative Example 4. Although the bright material does not affect the polishing glaze, and a tile with a smooth and delicate brick surface can be prepared, the bright material will affect the metal refraction effect of the gold decorative material, and then it will also affect the metal light sense, resulting in a poor gold decorative effect. The difference between Comparative Example 5 and Example 3 is that in Comparative Example 5, no organic silicon water-based polyurethane (adhesive) is added to the gold decorative material. In the subsequent polishing process, the gold decorative material falls off slightly, and the glaze defects increase, making the gold decorative effect worse than that of Example 3, and the corrosion resistance and antifouling performance of the glaze are also worse than those of Example 3. This shows that when preparing the gold decorative material, the application adds an appropriate amount of organic silicon water-based polyurethane (adhesive) to significantly improve the adhesion of the gold decorative material, reduce the occurrence of glaze defects, and indirectly improve the corrosion resistance and antifouling properties. The difference between Comparative Example 6 and Example 3 is that no basic frit is added in Comparative Example 6, which makes the metallic light sense of the appearance of the tile weak, and the glossiness, corrosion resistance and antifouling properties are all worse than those of Example 3. This shows that when preparing the gold decorative material, the application adds the preferred basic frit to reduce the brick surface defects that appear in the subsequent polishing process. The difference between Comparative Example 7 and Example 3 is that no suspending agent is added in Comparative Example 7, resulting in poor dispersion of the gold decorative effect material, which also affects the glossiness and brick surface effect. The difference between Comparative Example 8 and Example 3 is that the raw materials for preparing the suspension in Comparative Example 8 are different, and the 2'-(2'-hydroxy-3'-tert-butyl-5'-methylphenyl)-5-chlorobenzotriazole and 7 parts of tris(2,4-di-tert-butylphenyl)phosphite added in the suspension can play an anti-ultraviolet and anti-oxidation role, resulting in the poor environmental resistance of the gold decorative effect material in Comparative Example 8, which will also affect the use effect of the gold decorative material and the poor antifouling performance. The difference between Comparative Example 9 and Example 3 is that the gold decorative material in flaky form is used in Comparative Example 9, and the particle size is a single 20 mesh, but the refractive index is poor, and the glossiness of the brick surface is poor, indicating that the use of different gold decorative powders will affect the gold decorative effect, and the preferred gold decorative powder of the present application can improve the gold decorative effect.The difference between Comparative Example 10 and Example 3 is that the composition of the polishing glaze in Comparative Example 10 is different, resulting in brick surface defects such as pinholes in the subsequent polishing process, which in turn affects the gold decoration effect, and due to the brick surface defects, the anti-fouling performance is significantly worse than that of Example 3. In summary, the present application optimizes the bright material, gold decorative material and polishing glaze, and the synergistic effect can prepare tiles with a strong gold effect, good decorative beauty and experience, and can be mass-produced. In addition, the gold decorative powder used in Example 2 is irregular copper-aluminum alloy powder, which can also achieve the gold decoration effect, and in the preparation process, the copper-aluminum alloy powder is not oxidized to black or discolored, and has a cheaper source of raw materials, indicating that after the composition of the present application is optimized, the practicability and applicability are wider and can meet market demand.
