Description

Technical Field

[0001] This invention relates to the field of ceramic tiles, specifically to a translucent ceramic tile with a night rose stone-like design and its manufacturing process. Background Technology

[0002] Night Rose granite is a type of granite primarily sourced from Brazil. It features raised leaf and rose motifs, as well as recessed background sections, as shown in the attached image. Figure 1 The raw Night Rose stone has a unique gemstone color gradient, especially in the raised rose area. Existing technology can only produce a poor grayish-purple-blue color by wrapping red with sapphire blue or cobalt blue, and cannot achieve the gemstone color gradient of the raised rose area.

[0003] The unique decorative effect of Night Rose granite is also reflected in the translucent effect of the rose-shaped protrusions when backlit, such as... Figure 3 And the unique glossy-matte integrated decorative effect where the raised areas of the original stone have a glossy texture while the recessed areas of the background have a matte texture, such as... Figure 5 .

[0004] Due to the unique decorative effect of Night Rose granite, it is mainly used in high-end venues. Moreover, the stone is produced in small quantities and is expensive. There is little research on simulating the decorative effect of this stone surface with ceramic tiles, making Night Rose granite difficult to replicate with existing technology. Summary of the Invention

[0005] The purpose of this invention is to provide a manufacturing process for translucent ceramic tiles that mimic the shape of a night rose stone. The resulting ceramic tiles can achieve the gem-like color gradient of the rose-shaped protrusions in the original stone and the unique overall texture effect of the night rose stone, including the translucent effect of the rose-shaped protrusions when backlit and the integrated glossy and matte decorative effect.

[0006] To achieve the purpose of this invention, the present invention provides a manufacturing process for a translucent ceramic tile with imitation night rose stone positioning, the manufacturing process comprising the following steps:

[0007] S1. Prepare a translucent blank with a light transmittance ≥0.45% after firing, and then use translucent powder to press a translucent blank with raised leaves, raised roses and recessed background using a mold with a textured surface.

[0008] S2. Apply a known base glaze to the translucent blank in sequence, and then use inkjet printing to form a pattern layer that corresponds to the concave and convex texture of the translucent blank.

[0009] S3. Apply various colored dry granules to the rose-shaped raised areas of the pattern layer; apply shimmering dry granules with a glittering effect after firing to the background recesses of the pattern layer to obtain the pattern layer after the dry granules are applied. Both the colored dry granules and the shimmering dry granules are applied through a screen.

[0010] S4. Apply a matte protective glaze to the pattern layer;

[0011] S5. After being fired once in the kiln, the translucent ceramic tile with imitation night rose stone is obtained through a polishing process.

[0012] This invention utilizes a translucent body powder with a light transmittance of over 0.45% after firing, a translucent body with a textured surface prepared by stamping, and a pattern layer corresponding to the textured surface formed by inkjet printing. Various colored dry granules are applied to the raised rose areas of the pattern layer to create embellishments, while shimmering dry granules are applied to the recessed areas of the background. Finally, a matte protective glaze is applied, and the piece is fired and polished to obtain a translucent ceramic tile that mimics the unique overall texture of the original night rose stone. By using a translucent body and applying various colored dry granules to the raised rose areas, a gemstone-like color gradient effect with good color development and transparency is achieved after firing, similar to the original stone. Furthermore, the raised rose areas exhibit a translucent effect when backlit, an effect that cannot be achieved with conventional colored glazes. By applying shimmering dry granules and a matte protective glaze to the recessed areas of the pattern layer, a matte surface with a shimmering sandstone effect is formed after firing. Combined with the polished raised areas, a unique decorative effect integrating gloss and matte finishes is achieved.

[0013] Preferably, in step S2, applying the base glaze by spraying helps to obtain a base glaze of uniform thickness on an uneven translucent body. More preferably, removing the base glaze from the rose-shaped protrusions after applying the base glaze helps to improve the light transmission effect.

[0014] Preferably, the light transmittance of the translucent body after firing is 0.45-1.5%, and the light transmittance effect of the imitation night rose ceramic tile made within this preferred range is closest to that of the original night rose stone.

[0015] Specifically, the method for preparing a textured mold involves scanning the stone to obtain a design drawing of the textured mold, and then carving it according to the design drawing. In some embodiments, the raised roses and leaves in the textured mold design drawing are presented with different gray levels; in other embodiments, the relevant gray level data and three-dimensional data in the textured mold design drawing are adjusted. In this solution, the required screen printing plate is prepared based on the scanned textured mold design drawing.

[0016] Preferably, in step S3, the step of applying multiple colored dry granules includes: (1) printing positioning adhesive on the pattern layer through a full-screen printing press; (2) the screen includes a rose pattern, on which multiple different colored dry granules are applied to the rose protrusions.

[0017] Preferably, the raw materials for colored dry granules include base materials and inorganic pigments. The colored dry granules are obtained by first melting and firing the base materials, then pulverizing them, mixing them with inorganic pigments, and then firing them a second time in a melting furnace, followed by drying, pulverizing, and sieving. The base materials, by mass percentage, include: feldspar 20-45%, dolomite 1-14%, kaolin 4-8%, quartz 9-23%, calcite 12-18%, zinc oxide 10-26%, and titanium dioxide 1-8%. Among them, the titanium dioxide crystal form is rutile. The inorganic pigments are added externally based on the mass of the base materials, and the amount added is 0-21% of the mass of the base materials.

[0018] Preferably, the colored dry granules applied by the rose-shaped screen include 25-45% blue-purple dry granules, 45-65% purple-red dry granules, and 5-15% transparent dry granules by weight percentage. After mixing, they are applied through the rose-shaped screen. Taking the base material as a weight reference, the added inorganic pigment portion of the blue-purple dry granules is 1-3% cobalt oxide, the added inorganic pigment portion of the purple-red dry granules is 20-21% cobalt oxide, and the added inorganic pigment portion of the transparent dry granules is 0%.

[0019] In this invention, colored dry granules are applied to the rose-shaped protrusions of the printed positioning adhesive using a screen. Due to the addition of an appropriate amount of rutile-type titanium dioxide to the base material, the colored dry granules help to develop blue and purple colors after the addition of inorganic pigments. After mixing and melting various dry granules, different layered transition areas are formed. After firing, a gemstone color gradient consistent with the night rose stone is formed. When backlit, light can pass through the translucent body at the same time, presenting a more transparent gemstone color gradient and good light transmission effect at the rose-shaped protrusions (other parts of the tile are opaque except for the rose-shaped protrusions).

[0020] Preferably, in step S3, the screen further includes a background screen, on which the glitter particles are applied in the recesses of the background.

[0021] Specifically, the sources of scintillation dry particles can be mica flakes (biotite or muscovite), pearlescent powder, and zircon sand, etc.

[0022] Preferably, the chemical composition of the shimmering dry particles, by mass percentage, is: silicon dioxide 36-38%, aluminum oxide 4.5-5.5%, calcium oxide 4.5-5.3%, potassium oxide 0.3-0.7%, barium oxide 1.8-2.2%, zirconium dioxide 45-50%, hafnium dioxide 0.6-1.0%, and loss on ignition 0.4-1%. When these shimmering dry particles with the preferred chemical composition are added to the matte protective glaze, they form a good blend. After firing, they present a unique matte surface resembling shimmering sandstone in the background recesses, further enriching the texture and decorative effect of the translucent ceramic tile with its imitation night rose stone design.

[0023] Preferably, the particle size of colored dry granules and glitter dry granules is 60 mesh to 150 mesh.

[0024] Preferably, the screen printing mesh count is 60-120 mesh.

[0025] Preferably, the height of the leaf protrusion is 0.3-0.4 mm, and the height of the rose protrusion is 0.5-0.7 mm.

[0026] Preferably, in step S5, the polishing process involves coarse polishing, medium polishing, and fine polishing sequentially. The coarse polishing process parameters include 8-12 sets of low-gloss grinding blocks (the grinding block material is a relatively rough type, such as silicon carbide, which cannot polish the brick blank). The low-gloss grinding blocks include 4-6 sets of 1500-mesh first low-gloss grinding blocks and 4-6 sets of 2000-mesh second low-gloss grinding blocks. The medium polishing process parameters include 9-11 sets of 240-mesh diamond brushes, 5-6 sets of 180-mesh rubber brushes, and 5-6 sets of 240-mesh sharp fiber polishers. The fine polishing process parameters include 9-11 sets of 240-mesh sharp fiber polishers and 9-11 sets of 240-mesh fiber polishers. The mesh numbers of the diamond brush, rubber brush, and fiber polisher refer to the diameter of the corresponding brush. Sharp fiber polishers have stronger cutting force than regular fiber polishers. Both sharp fiber polishers and regular fiber polishers mainly use fiber wheels, while sharp fiber polishers also incorporate some steel wool and nylon fibers to improve cutting performance.

[0027] The combination of the raised height and polishing parameters in this scheme helps to achieve a pattern decoration effect where the matte protective glaze on the raised areas is polished off and brightened after polishing, while the recessed areas of the background are not polished.

[0028] The present invention also provides a ceramic tile, which is prepared by the preparation process of the imitation night rose stone positioning translucent ceramic tile of any of the aforementioned schemes, and has the technical effects of the corresponding preparation process, which will not be elaborated here.

[0038] Performance characterization methods:

[0039] (1) Similarity of texture and color: The tested ceramic tile and the original night rose stone (hereinafter referred to as the tested ceramic tile and the original stone) were blindly tested. 100 testers distinguished the unmarked tested ceramic tile and the original stone by focusing on the overall texture effect and the unique gradient color of the rose-shaped protrusions. The overall texture effect and the rose-shaped protrusions were considered to be "no difference" if they were relatively consistent. After the distinction, they checked "different" and "no difference". The number of people who thought "no difference" was counted to obtain the corresponding proportion (proportion = number of people / total number of people * 100%). If the proportion is below 40%, the tested ceramic tile is considered to be significantly different from the original stone. If the proportion is between 40% and 60%, the tested ceramic tile is considered to be not significantly different from the original stone. If the proportion is above 60%, the tested ceramic tile is considered to be highly similar to the original stone. If the proportion is above 80%, the tested ceramic tile is considered to be extremely similar to the original stone.

[0040] (2) Light transmittance: The light transmittance at 10mm was measured using an LS117 optical density meter (brand: linshang). The light transmittance of Night Rose stone was measured to be 0.45-1.5%.

[0041] (3) Gloss: Measured using a photometer. The gloss of the Night Rose raw stone was measured to be 15-19° in the recessed area and 32-38° at the tip of the raised area.

The screen printing mesh count is 60 mesh.

[0050] The raw materials for colored dry granules include base materials and inorganic pigments.

[0060] The raw materials and preparation steps for preparing the ceramic tile to be tested are the same as in Example 1, except that in step 3, the composition of the base material in the specific colored dry granules is as shown in the table below (unit: %).

[0062] Comparative Example 1

[0063] The raw materials and preparation steps for preparing the ceramic tile to be tested are the same as in Example 1, except that in step 3, titanium dioxide is not added, and other components are adapted accordingly. The raw material composition of the base material in the specific colored dry granules is shown in the table above.

[0064] Comparative Example 2

[0065] The ceramic tile to be tested was prepared using the same raw materials and preparation steps as in Example 1, except that in step 3, the titanium dioxide crystal form was anatase.

[0066] Examples 6 to 8, Comparative Examples 3 to 9

[0067] The ceramic tile to be tested was prepared using the same raw materials and preparation steps as in Example 1, except that in step 3, the mass composition of the blue-purple, purple-red, and transparent dry particles in the colored dry particles was adjusted, and other components were adjusted accordingly, as shown in the table below (unit: %).

[0069] The tiles to be tested were inspected, and the results are shown in the table below:

[0070]

[0071]

[0072] As can be seen from the data of Examples 1 to 8 in the table above, within the preferred range of the raw material composition and dry particle quality composition of the base material of colored dry granules, the prepared ceramic tile forms a gemstone color gradient at the rose-shaped protrusion. The imitation night rose stone positioning translucent ceramic tile prepared in this application can achieve an extremely high degree of similarity in texture and color with the rose-shaped protrusion of the original night rose stone (>80%), a light-transmitting effect at the rose-shaped protrusion when backlit, and a glossy and matte integrated decorative effect formed between the glossy surface at 30-40° and the matte surface at 13-19° of the background recess.

[0073] As can be seen from the comparison of Comparative Examples 1-2 and Example 1, when titanium dioxide is not added to the base material of colored dry granules or when the titanium dioxide crystal form is replaced with anatase, the color development is not ideal, and there are cases where the color cannot be developed or the color is yellowish. When combined with inorganic pigments, it is impossible to produce the ideal blue and purple color development. The final color gradient is significantly less similar to the texture and color of the rose-shaped raised area on the surface of the Night Rose raw stone.

[0074] As can be seen from the comparison of Comparative Examples 3-9 and Example 1, when the mass ratio of blue-purple dry particles, purple-red dry particles and transparent dry particles in the corresponding colored dry particles is not within the preferred range, the similarity of texture color or light transmission effect of the rose-shaped texture of the Night Rose raw stone decreases.

[0075] Example 1 is the best embodiment, exhibiting a very high degree of similarity in texture and color to the Night Rose natural stone. The Night Rose natural stone and the tested ceramic tile in Example 1 can be used as a reference. Figure 1 and Figure 2 Under backlighting conditions, the light transmittance of the original stone and the tested ceramic tile can be referenced. Figure 3 and Figure 4 When a section of the tile or raw stone is magnified, the integrated glossy and matte pattern decoration effect of the raw stone and the tile under test can be seen. The matte surface presents a shimmering sandstone effect, as shown in the reference. Figure 5 and Figure 6 .
