[0002] Brick blank is a key stage in the production process of ceramic tiles. The quality of brick blank directly affects the quality and performance of ceramic tiles. Therefore, in the production process of ceramic tiles, the production process and quality requirements of brick blank are very high. Stamping forming is a common method for producing ceramic tiles. The raw materials are pressed by high-pressure forming to form ceramic tiles with dense structure and precise size. This production method has the advantages of high production efficiency and conducive to the realization of automated production. It has been widely used in ceramic tile production.

[0003] If the surface of the ceramic tile is too flat, when the adhesive is applied to the surface of the tile, it is difficult for the adhesive to solidify and form a stable anchoring state. The difference in bonding stress between the tile and the adhesive will lead to a decrease in the overall bonding strength, which will easily lead to the tile being easily hollowed and falling off during use, resulting in poor overall tile paving performance. Contents of utility model

[0004] The main purpose of the utility model is to provide a stamped ceramic tile blank and ceramic tile, so that the paving surface has a three-dimensional undulating bonding interface structure, aiming to solve the problem of poor bonding effect between the surface of the ceramic tile blank and the adhesive, easy hollowing and falling off, and low tile paving performance.

[0005] To achieve the above-mentioned purpose, the utility model proposes a stamping-molded ceramic tile blank, including a tile blank body, a surface of which is provided with a plurality of convex portions and a plurality of concave portions, wherein the plurality of convex portions and the plurality of concave portions are staggered on the surface of the tile blank body in a first direction;

[0039] The present utility model provides a stamping formed ceramic tile blank.

[0040] In the embodiments of the present utility model, as Figure 1 and Figure 2 shown, a stamping formed ceramic tile blank includes a tile blank body 1, and a plurality of convex portions 2 and a plurality of concave portions 3 are provided on one surface of the tile blank body 1. The plurality of convex portions 2 and the plurality of concave portions 3 are alternately arranged in a first direction on the surface of the tile blank body 1;

[0041] And / or, the cross-sectional shapes of the plurality of convex portions 2 in the height direction are the same or different;

[0042] And / or, the cross-sectional shapes of the plurality of convex portions 2 are the same or different;

[0043] And / or, the outer contour shapes of the plurality of concave portions 3 are the same or different;

[0044] And / or, the cross-sectional shapes of the plurality of concave portions 3 are the same or different.

[0045] In the technical solution of the present utility model, a plurality of convex portions 2 and a plurality of concave portions 3 are arranged on one surface of the brick blank body 1. The plurality of convex portions 2 and the plurality of concave portions 3 are arranged alternately in the first direction. The cross-sectional shapes and cross-sectional shapes of the convex portions 2 in the height direction are the same or different, and the outer contour shapes and cross-sectional shapes of the concave portions 3 are the same or different. Through reasonable dense arrangement combination and design layout, the ceramic brick blank and the binder are further tightly anchored and engaged together, which not only effectively improves the bonding effect between the ceramic brick blank and the bonding material, but also reduces the occurrence of the phenomenon of "hollow drum and falling off" during the use of the ceramic brick, improves the tiling performance of the ceramic tile, and greatly reduces the safety risk caused by the "hollow drum and falling off" of the ceramic brick.

[0046] The die stamping production method is more flexible. The forms of the convex portions 2 and the concave portions 3 can be selected hierarchically, and reasonable dense arrangement combination and design layout are carried out to form a die-stamped ceramic brick blank with convex portions 2 and concave portions 3, further meeting the production requirements of different ceramic tiles. By increasing the adhesion and structural stability between the ceramic brick blank and the adhesive, the best tiling use function is achieved, and the falling off of the ceramic tile is effectively prevented.

[0047] The forms of the convex portions 2 and the concave portions 3 formed by the die stamping forming method are such as blind holes, grooves, columns, platforms, inclined surfaces, curved surfaces, etc. The formed ceramic brick blank has higher density and strength, and also has precise dimensions and shapes. Through reasonable arrangement combination and design layout, a ceramic brick blank with a two-dimensional bonding interface is formed on the surface of the one-dimensional plane ceramic brick blank, and a rich structure is formed on the surface of the ceramic brick blank, so that the surface thereof has a three-dimensional undulating bonding interface structure, further improving the aesthetics, use performance and product quality of the product, greatly shortening the production cycle, and improving the production efficiency.

[0048] Please refer to Figure 3, in an embodiment of the present application, a plurality of convex portions 2 and a plurality of concave portions 3 are alternately arranged in the second direction on the surface of the brick blank body 1. The alternating design of the convex portions 2 and the concave portions 3 further improves the bonding force between the ceramic brick blank and the adhesive, continuously improves the bonding effect between the two, and can also add texture and layering to the surface of the ceramic brick blank. In addition, when the ceramic brick blank is subjected to an external force, through the alternately arranged convex portions 2 and concave portions 3, there are more contact points to disperse and transfer stress, thereby improving the impact resistance and compressive resistance of the brick blank and further increasing the structural stability of the ceramic brick blank.

[0049] Please refer to Figure 4 , in an embodiment of the present application, a plurality of convex portions 2 are arranged at intervals in the second direction; a plurality of concave portions 3 are arranged at intervals in the second direction. The arrangement at intervals can, to a certain extent, reduce the material consumption and can also form a more complex structure on the surface of the ceramic brick blank. These structures can disperse stress and improve the compressive strength and impact resistance of the ceramic brick blank.

[0050] In an embodiment of the present application, in the height direction, with the surface of the brick blank body 1 provided with the convex portions 2 and the concave portions 3 as the reference plane 4, the convex portions 2 are 0.2 mm to 1.5 mm higher than the reference plane 4, and the concave portions 3 are 0.5 mm to 3.0 mm lower than the reference plane 4. If the height of the convex portions 2 is too high, it will affect the subsequent process. For example, during the firing process, if the height of the convex portions 2 is too high, it is more likely to be unevenly heated, causing the brick blank to warp, resulting in distortion and affecting the flatness and aesthetics of the product. If the height of the concave portions 3 is too high, the crack resistance of the ceramic brick blank will be reduced. When subjected to an external impact or temperature change, the ceramic brick blank is more likely to crack or break, thereby affecting the service life and performance of the ceramic brick. Therefore, the heights of both the convex portions 2 and the concave portions 3 need to be within a suitable range.

[0051] Please refer to Figure 1 、 2Between 5 and 10, in an embodiment of the present application, the cross-sectional shape of the convex portion 2 in the height direction is rectangular, triangular or arched; and / or, the cross-sectional shape of the convex portion 2 is polygonal, circular, annular or arc-shaped; and / or, the outer contour shape of the concave portion 3 is U-shaped or V-shaped; and / or, the cross-sectional shape of the concave portion 3 is polygonal, circular, annular or arc-shaped. Optionally, the convex portion 2 is a column or a platform. Optionally, the concave portion 3 is a hole, a groove or a slot. Filling the holes, grooves and slots with an adhesive can effectively enhance the adhesion between the ceramic tile and the adhesive, and form a firm connection after drying, which helps to prevent the ceramic tile from moving or warping during use, thereby improving the installation stability and safety. In addition, the concave portion 3 can guide the flow of the adhesive to a certain extent, ensuring that the adhesive is evenly distributed on the surface of the ceramic tile blank, further improving the installation stability. Through specific patterns and layouts, and combinatorial designs, the convex portion 2 and the concave portion 3 further have excellent adhesion performance with the binder, and also increase the sense of hierarchy and three-dimensionality of the space of the ceramic tile blank, with a unique design. In practical applications, various convex portions 2 and various concave portions 3 are used in combination as needed.

[0052] Optionally, the widths of both the column and the platform are 2.0 mm to 10 mm, the heights are both 0.5 mm to 1.5 mm, and the height of the column is greater than the height of the platform.

[0053] Optionally, the hole is a circular blind hole, a polygonal blind hole, or a blind ring hole. The blind hole can provide a larger contact area with the adhesive compared to the blind ring hole. The blind ring hole presents a circular depression, or can also present an elliptical ring-shaped depression. The polygonal blind hole can be in shapes such as triangular, square, rectangular, hexagonal, etc., which provide unique geometric shapes and can further enhance the richness and beauty of the surface texture of the ceramic tile. Optionally, the diameters of the blind holes and the outer diameters of the blind ring holes are both 4.0 mm to 20 mm, the hole depths are both 0.5 mm to 3.0 mm, and the inner diameters of the blind ring holes are 4.0 mm to 14 mm. Using the same outer diameter for the blind holes and the blind ring holes allows for a more unified mold, which not only reduces the complexity in the production process, improves production efficiency, but also reduces the number of molds of different sizes and lowers production costs. A concave portion 3 with an appropriate depth can ensure sufficient accommodation of the adhesive while not being too deep to affect the overall strength of the ceramic tile.

[0054] Optionally, the widths of both the groove and the slot are 2.0 mm to 10 mm, and the depths are both 0.5 mm to 1.5 mm. Using the same width and depth for the groove and the slot can further simplify and unify the mold design of the ceramic tile, contribute to reducing production costs and improving production efficiency, and can also create a cleaner, more unified and aesthetic visual effect, enhancing the overall design sense of the ceramic tile and making the product more attractive.

[0055] Please refer to Figure 1 and 9, in an embodiment of the present application, the recess 3 has a bottom edge 5 that forms an angle θ with the length direction of the brick blank body 1. The bottom edge 5 of the recess 3 forms a certain angle with the brick blank body 1, which is beneficial to improving the compressive strength of the ceramic brick blank and can further improve the overall structural stability of the ceramic brick.

[0056] Please refer to Figure 1 , in an embodiment of the present application, the bottom edge 5 includes an inclined plane area 51 and / or an arc area 52. In this embodiment, the bottom edge 5 of the recess 3 includes an inclined plane area 51 and / or an arc area 52. The arc area 52 can significantly improve the demolding process after stamping, improving product quality and production efficiency. Optionally, the arc area 52 is obtained by the plane where the inclined plane area 51 is located being tangent to the vertical plane in the height direction. Optionally, the highest point of the inclined plane area 51 in the height direction is higher than the reference plane 4. Optionally, the highest point of the arc area 52 in the height direction is at the same height as the reference plane 4. The arc surface design of the arc area 52 makes the shape of the brick blank body 1 in the mold more continuous, without sharp corners or right angles. This smooth shape helps to reduce the contact area and stress concentration points between the product and the mold during the demolding process, and can also effectively reduce the friction force between the product and the mold, thereby achieving a reduction in the demolding difficulty.

[0057] Please refer to Figure 1 , in an embodiment of the present application, the angle θ between the inclined plane area 51 and the length direction of the brick blank body 1 is not greater than 5°, and the radius of the arc area 52 is 2 mm to 6 mm. The arc surface formed by the arc area 52 has a smoother and more flowing transition compared to a right angle or an acute angle edge. During demolding, it can effectively reduce the friction force between the product and the mold, reduce the demolding difficulty, and improve product quality and production efficiency.

[0058] Optionally, the bottom edge 5 includes an arc area 52. At this time, the height difference between the lowest point of the arc area 52 and the reference plane 4 is 0.2 mm to 1.0 mm. The cross-sectional shape of the convex part 2 in the height direction is arched, and the height difference between the highest point of the convex part 2 and the reference plane 4 is 0.2 mm to 1.0 mm. At this time, the bottom edge of the recess 3 formed by the convex part 2 and this arc area 52 presents a unique curved surface texture visually. The combination of the two has a cross-sectional shape of a wavy pattern in the height direction, increasing the artistic sense and layering of the space, and can meet the personalized needs of different consumers. At this time, the arc area 52 is also beneficial for demolding after stamping, reducing the resistance and stress concentration during demolding, and further improving the integrity and surface quality of the product.
