Description

Technical Field

[0001] The invention relates to the field of building ceramics, and in particular to a colorful marble tile and a manufacturing method thereof. Background Art

[0002] Traditional marble tile manufacturing focuses on texture and inkjet color matching. It is difficult to effectively express the color changes caused by the refraction of light in the stone crystals in natural marble. However, the color effect produced by the decomposition of light by these stone crystals is the most fascinating part of the stone.

[0003] Currently, when making the iridescent dry particle glaze layer in the industry, transparent dry particles are usually used as the base material, in which a small amount of glittering dry particles (1-3%) are mixed and applied to the entire surface to achieve the effect of sporadic glittering on the brick surface. It cannot truly and completely replicate the iridescent effect of natural marble, but if the amount of glittering dry particles added is too large, it will affect the clarity of the brick surface texture. Summary of the invention

[0004] In view of the above problems, the present invention provides a colorful marble and a method for manufacturing the same by improving the composition and process of the existing colorful dry particle glaze layer.

[0005] To achieve the above object, the technical solution adopted by the present invention is:

[0006] A method for manufacturing colorful marble comprises the following steps:

[0007] (1) Applying a base glaze on the surface of the ceramic tile blank and then inkjet printing a marble texture pattern;

[0008] (2) applying colored glaze by screen printing on the surface of the ceramic tile obtained in step (1);

[0009] (3) applying a colorful dry granule glaze locally on the surface of the colored glaze, wherein the colorful dry granule glaze is mixed with 40-50 parts of transparent dry granules, 20-30 parts of scintillating dry granules, 20-30 parts of printing ink, and 10-15 parts of printing paste; in terms of weight percentage, the chemical composition of the transparent dry granules is SiO2 55-60%, Al2O3 5.5-8.5%, Fe2O3 0-0.3%, CaO 10-15%, MgO 0.2-0.3%, BaO 1.5-4%, ZnO 8-15%, K2O 5-9%, Na2O 0-3%, ZrO2 0.2-0.5%, TiO2 0-1.5%, and the rest is ignition loss; the chemical composition of the scintillating dry granules is SiO2 30-40%, ZrO2 60-70%, Al2O3 0-1%, CaO0-1%, TiO2 0-1%, and the rest is loss on ignition;

[0010] (4) applying protective glaze on the surface of the ceramic tile obtained in step (3);

[0011] (5) firing the bricks obtained in step (4) into shape;

[0012] (6) Polishing and waxing the bricks obtained in step (5).

[0013] The scheme of the present invention can increase the proportion of shimmering dry materials in the shimmering dry granular glaze by adopting local fixed-point application of the shimmering dry granular glaze. Moreover, in the shimmering dry granular glaze, since the transparent dry granules used in the present invention have a low melting point, during the firing process, the shimmering dry granules with a high melting point are first melted and wrapped, so that the wrapped shimmering dry granules in the glaze layer can be stacked layer by layer to form a light refraction layer, thereby forming a more realistic shimmering effect. Further combined with the protective glaze layer, since the protective glaze has a certain thickness in the glaze layer, it can be fully polished to make the brick surface smooth without damaging the underglaze layer. It can provide a higher cutting amount for the polishing of the brick surface without affecting the anti-fouling and other properties of the brick surface. Moreover, since a layer of protective glaze is poured on the surface, the shimmering dry particles are distributed above and below the glaze layer, forming a three-dimensional shimmering shimmering effect, and even polishing will not affect the three-dimensional effect of the shimmering shimmering on the surface. Moreover, after polishing and waxing, the brick surface is smoothed. Due to the high gloss, good flatness and transparent glaze of the brick surface, the light can well illuminate the shimmering dry particles in the glaze and be refracted by a large number of shimmering dry particles, producing a realistic fantasy color gradient effect.

[0014] Preferably, in step (2), the screen is adjusted so that the colors of different textures of the screen are intertwined, so that the transition of the tiles is natural, which can make up for the shortcomings of inkjet printing in color richness, brightness and layering, and enhance the ornamental value of the marble tiles.

[0015] Preferably, in step (3), in the colorful dry particle glaze, the ratio of colorful dry particles to scintillating dry particles is 1:0.4-0.6 by mass, and the finally obtained ceramic tile has good colorful effect and modulus of rupture.

[0016] Preferably, in step (3), the amount of the colorful dry granular glaze applied is 1-1.2 kg / m 2 , thickness 0.75-1.5mm.

[0017] Preferably, in step (3), the particle size of the transparent dry particles is 37-75 μm, and the particle size of the scintillation dry particles is 150-250 μm.

[0018] Preferably, in step (4), the protective glaze is a slurry formed by dispersing protective glaze powder in water, wherein the chemical composition of the protective glaze powder is SiO2 40-45%, Al2O3 6-10%, Fe2O3≤0.3%, CaO 6-10%, MgO 3-6%, BaO 7-12%, ZnO 3-6%, K2O 2-5%, Na2O 2-5%, SrO 2-5%, SO3 1-2.5%, TiO2≤0.5%, and the rest is loss on ignition.

[0019] Preferably, in step (4), the amount of protective glaze applied is 400-600 g / m 2 , in order to reach a certain thickness, which is conducive to polishing and waxing to form a smooth and bright surface.

[0020] Preferably, in step (5), the firing temperature is 1185-1225° C. and the firing time is 45-60 min. If the temperature is too low or the time is too short, the glaze of the tile will not be completely melted and vitrified, thus affecting the transparency of the tile surface.

[0021] Preferably, in step (6), the brightness of the base brick surface after polishing is between 70°-80°, and the brightness of the base brick surface after waxing is between 90°-100°, so that the brick surface is smooth and transparent, and under the irradiation of light, the magic color effect is better presented locally.

[0022] Preferably, in step (6), the polishing process is to first use 10 groups of 400-mesh elastic grinding blocks, 10 groups of 600-mesh elastic grinding blocks, and a pressure of 4kg; then 10 groups of 800-mesh elastic grinding blocks, 10 groups of 1000-mesh elastic modules, and a pressure of 2kg; and finally 20 groups of 240-mesh sponge polishing, and a pressure of 0.5kg. The waxing process can choose commonly used ceramic polishing wax. For example, in a specific embodiment of the present invention, Shuangyi Zhongguang wax is used, and the dripping amount is 12-15g / m 2

[0023] Another aspect of the present invention also provides a colorful marble tile prepared by the above manufacturing method.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] The scheme of the present invention improves the components of the colorful dry granule glaze and applies the colorful dry granule glaze locally, so that the fired marble tiles can form a realistic colorful effect without affecting the overall texture clarity of the tile surface. In addition, since a layer of transparent protective glaze of a certain thickness is poured on the surface, the flashing dry particles are distributed above and below the glaze layer, forming a three-dimensional flashing colorful effect. Even polishing will not affect the three-dimensional effect of the flashing colorful surface. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Figure 1 This is a schematic diagram of the firing effect of tiles in Example 1 of the present invention. DETAILED DESCRIPTION

[0027] The present invention is further described by the following embodiments, and it should be understood that the following embodiments are only used to illustrate the present invention, but not to limit the present invention. In the absence of special instructions, the parts are all parts by weight.

[0028] The following is an exemplary description of the method for manufacturing the colorful marble tile of the present invention.

[0029] A method for manufacturing colorful marble comprises the following steps:

[0030] (1) Applying a base glaze on the surface of the ceramic tile blank and then inkjet printing a marble texture pattern;

[0031] The green body can be obtained by forming ordinary ceramic base materials through a press.

[0032] Then, the green body can be dried for 1 to 1.5 hours, and the moisture content of the dried green body can be controlled at 0.3 to 0.5%.

[0033] Then, a base glaze is applied on the blank. The base glaze material is not particularly limited, and the base glaze material known in the art can be used.

[0034] There is no special requirement for the method of applying the base glaze, and the conventional method of preparing the glaze slurry in the art can be used, such as spraying the glaze with an inkjet printer.

[0035] Printing marble texture patterns on the base glaze layer can be done with a digital inkjet printer. The ceramic inks used can be blue, brown, orange, lemon yellow, black, red, etc.

[0036] (2) Applying colored glaze by screen printing on the surface of the ceramic tile obtained in step (1).

[0037] Color glaze is applied on the surface of the blank after inkjet printing by screen printing, and different color glazes are selected according to needs. The screen printing method can be a conventional method in the art. By applying the color glaze, the color can be further enriched.

[0038] (3) Apply colorful dry granular glaze locally on the surface of the colored glaze.

[0039] Usually, the iridescent glaze is applied all over the surface, but the solution of the present invention adopts partial application to highlight the iridescent effect and avoid the problem of flickering and lack of iridescent effect caused by small amount of iridescent dry material when applying all over the surface.

[0040] The colorful dry granule glaze used in the scheme of the present invention is mixed with 40-50 parts of transparent dry granules, 20-30 parts of scintillating dry granules, 20-30 parts of printing oil, and 10-15 parts of printing paste. The chemical composition of the transparent dry granules is SiO2 55-60%, Al2O3 5.5-8.5%, Fe2O3 0-0.3%, CaO 10-15%, MgO 0.2-0.3%, BaO 1.5-4%, ZnO 8-15%, K2O 5-9%, Na2O0-3%, ZrO2 0.2-0.5%, TiO2 0-1.5%; the chemical composition of the scintillating dry granules is SiO2 30-40%, ZrO2 60-70%, Al2O3 0-1%, CaO 0-1%, TiO2 0-1%.

[0041] Preferably, in the colorful dry particle glaze, the ratio of transparent dry particles to scintillating dry particles is 1:0.4-0.6 (mass ratio). In this way, not only the finally obtained ceramic tile has a good colorful effect, but also the product has a good modulus of rupture and strong impact resistance.

[0042] The printing ink and printing paste are the printing ink and printing paste raw materials commonly used in the ceramic field. Preferably, the viscosity of the printing ink is 1000-1200 mpa·s, and the viscosity of the printing paste is 7000-7500 mpa·s.

[0043] Preferably, the amount of the colorful dry granular glaze applied is 1-1.2 kg / m 2 , thickness 0.75-1.5mm.

[0044] Preferably, the particle size of the transparent dry particles is 37-75 μm, and the particle size of the scintillation dry particles is 150-250 μm.

[0045] By adopting local fixed-point application of the fantasy color dry particle glaze, the proportion of shimmering dry materials in the fantasy color dry particle glaze can be increased. Moreover, in the fantasy color dry particle glaze of the present invention, by optimizing the composition of transparent dry materials and shimmering dry particles, the transparent dry particles have a lower melting point. During the firing process, the shimmering dry particles with a high melting point are melted first, so that the shimmering dry particles wrapped in the glaze layer can be stacked layer by layer to form a light refraction layer, thereby forming a more realistic fantasy color effect.

[0046] (4) applying protective glaze on the surface of the ceramic tile obtained in step (3).

[0047] By pouring protective glaze, the glaze layer has a certain thickness after firing, and it can be fully polished to make the brick surface flat without damaging the iridescent layer under the glaze. It can provide a higher cutting amount for brick surface polishing without affecting the anti-fouling properties of the brick surface. Moreover, after polishing and waxing, the brick surface is smoothed. Due to the high gloss, good flatness and transparent glaze surface of the brick surface, the light can well illuminate the glittering dry particles in the glaze surface, and refracted by a large number of glittering dry particles, producing a realistic iridescent gradient effect.

[0048] Protective glaze is a slurry formed by dispersing protective glaze powder in water to facilitate pouring glaze. Commonly used dispersants include sodium tripolyphosphate, sodium methyl cellulose, etc. Protective glaze is usually obtained by mixing protective glaze powder, water and dispersant by ball milling.

[0049] The chemical composition of the protective glaze powder of the protective glaze of the present invention is SiO2 40-45%, Al2O3 6-10%, Fe2O3≤0.3%, CaO 6-10%, MgO 3-6%, BaO 7-12%, ZnO 3-6%, K2O 2-5%, Na2O 2-5%, SrO 2-5%, SO3 1-2.5%, TiO2≤0.5%, and the rest is loss on ignition.

[0050] Preferably, the amount of protective glaze applied is 400-600g / m 2 , in order to reach a certain thickness, which is conducive to polishing and waxing to form a smooth and bright surface.

[0051] In a specific embodiment of the present invention, the protective glaze is prepared by ball-milling 66.3 parts of protective glaze powder, 33.2 parts of clean water, 0.3 parts of sodium tripolyphosphate, and 0.2 parts of sodium methyl cellulose.

[0052] (5) firing the bricks obtained in step (4) into shape;

[0053] The green body is put into the kiln for firing. The firing temperature is 1185-1225℃ and the firing time is 45-60min. If the temperature is too low or the firing time is too short, it is easy to cause the glaze of the tile to not be completely melted and vitrified, affecting the transparency of the tile surface.

[0054] (6) Polishing and waxing the bricks obtained in step (5).

[0055] After firing, it can be polished and waxed. For example, the surface of the tile can be polished with a high-speed rotating diamond brush to make it present a marble-like texture and a magical effect. It can be fully polished to make the surface have a higher gloss and flatness. Full polishing means that the entire surface is polished, and the polishing thickness is thicker, for example, 0.1-0.4mm, to polish the surface into a mirror effect. Through full polishing, a part can be polished off, with a certain glossiness, such as 25-35 degrees. It can also be half-polished. Half-polishing means that the surface is polished to increase the glossiness.

[0056] Preferably, the brightness of the base brick surface after polishing is between 70-80°, and the brightness of the base brick surface after waxing is between 90°-100°, so that the brick surface is smooth and transparent, and under the irradiation of light, the fantasy color effect is better presented locally.

[0057] Preferably, the polishing process is to first use 10 groups of 400 mesh elastic grinding blocks, 10 groups of 600 mesh elastic grinding blocks, and a pressure of 4kg; then 10 groups of 800 mesh elastic grinding blocks, 10 groups of 1000 mesh elastic modules, and a pressure of 2kg; and finally 20 groups of 240 mesh sponge polishing, and a pressure of 0.5kg. The waxing process can choose commonly used ceramic polishing wax. For example, in a specific embodiment of the present invention, Shuangyi Zhongguang wax is used, and the drop coating amount is 12-15g / m 2 .

[0110] Comparative Example 1

[0111] The difference from Example 1 is that the amount of each component in the magic color dry particle glaze is different, and the mass ratio is transparent dry particles: scintillating dry particles = 3:1, and the rest are the same. The modulus of rupture of the final obtained tile is 46.7 MPa, but due to the small amount of scintillating dry particles accumulated in the glaze layer, the magic color effect is not obvious.

[0112] Comparative Example 2

[0113] The difference from Example 1 is that the amount of each component in the magic color dry granule glaze is different. According to the mass ratio, the transparent dry granules: the scintillating dry granules = 5:7, and the rest are the same. The modulus of rupture of the final tile is 41.6 MPa. Since the amount of scintillating dry granules accumulated in the glaze layer is too large, they cannot be completely wrapped during the firing process, resulting in cracks inside the glaze layer, affecting the surface effect and reducing the performance of the tile surface.
