Description

Technical Field

[0001] This invention relates to the field of ceramic tile technology, and in particular to a soft-light marble ceramic tile and its preparation process. Background Technology

[0002] As a type of ceramic tile, soft-light tiles scatter light when it shines on their surface, resulting in a more delicate and smooth light feel, more comfortable visual experience, and no light pollution problem. Therefore, they have been widely used in recent years.

[0003] Currently, the production process of soft-gloss tiles requires a polishing step. Existing processes still use high-amount (smaller mesh) polishing blocks to achieve a soft-gloss effect. However, for marble-look ceramic tiles with a protective glaze applied via screen printing, the glaze layer is thin and contains many closed pores. Using high-amount polishing blocks can easily penetrate the glaze layer and expose these pores, reducing their stain resistance. Therefore, some manufacturers apply a stain-resistant wax layer to the surface of the ceramic tiles to further enhance their gloss and achieve a soft-gloss effect, while also improving their stain resistance. However, because the wax layer is thin and has limited adhesion to the tile surface, it is easily damaged during use, leading to stain-resistant failure. Summary of the Invention

[0004] The main objective of this invention is to provide a soft-light marble tile and its preparation process, aiming to improve the technical problem of poor stain resistance of existing soft-light marble tiles.

[0005] To achieve the above objectives, this invention proposes a manufacturing process for soft-light marble ceramic tiles, characterized by the following steps:

[0006] S1. Polish the surface of the marble tile in sequence using an elastic grinding block, a diamond grinding brush, and a fiber brush;

[0007] Wherein, the mesh size of the elastic abrasive block is ≥1500 mesh, and the mesh size of the fiber brush and the diamond abrasive brush is ≤600 mesh;

[0008] S2. Continue to apply a soft-polish wax to the surface of the marble tile;

[0009] S3. Continue to coat the surface of the marble tile with anti-fouling wax to obtain the soft-gloss marble tile.

[0010] To prevent the stain-resistant properties of ceramic tiles from failing after long-term use, the tiles or glaze themselves should have a certain degree of stain resistance.

[0011] In the above-mentioned preparation process of soft-light marble tiles, the surface of the tiles needs to be treated by polishing. Specifically, the following steps are included: the tile body with protective glaze applied by screen printing is fired to obtain the finished marble tile. Due to the high sintering temperature of the glaze, the surface hardness is also higher and the wear resistance is better. At the same time, the surface of the sintered tile has more and more obvious uneven structure and more closed pores inside the tile.

[0012] The tile surface is micro-polished using high-grit elastic abrasive blocks; then, the micro-polished tile is polished with a diamond rubber brush; after polishing, a fiber brush is used to repair abrasion marks and scratches caused by polishing, resulting in a final polished gloss of approximately 18-25°. In this polishing process, the tile is first polished with high-grit elastic abrasive blocks, then with low-grit diamond brushes and fiber brushes, preventing the tile's inherent uneven structure from being excessively removed, thus maintaining good anti-slip properties. After repair with a fiber brush, a wax containing superhydrophilic hybrid polysiloxanes is used as a smoothing wax to further enhance the gloss and anti-slip effect, maintaining a gloss of 50-75°. Finally, an anti-fouling wax is applied to the waxed surface to further enhance its stain resistance.

[0013] Preferably, in step S1, the elastic abrasive blocks include ≤6 groups of 1500-mesh first elastic abrasive blocks, 4-8 groups of 3000-mesh second elastic abrasive blocks, and 4-8 groups of 5000-mesh third elastic abrasive blocks arranged sequentially; the elastic abrasive blocks include 14-18 groups.

[0014] The grit size and arrangement of the polishing blocks need to be adjusted according to the specific polishing requirements, primarily to ensure that the tile maintains a glaze structure with good anti-slip properties. In this design, there should be ≤6 sets of 1500-grit elastic blocks, ideally 5-6 sets; 4-8 sets of 3000-grit blocks, preferably 5-6 sets; and 4-8 sets of 5000-grit blocks, preferably 4-6 sets. These three high-grit elastic blocks primarily provide an appropriate cutting amount to the tile surface, maintaining good anti-slip properties. Regarding quantity, too few elastic blocks will fail to remove surface bumps, while too many will expose closed pores, affecting the tile's stain resistance. Therefore, the total number of elastic blocks in this design should ideally be between 14-18 sets.

[0015] Preferably, in step S1, the diamond brush includes 20-30 sets of 320-mesh first diamond brushes and ≥6 sets of 400-mesh second diamond brushes arranged sequentially, and the diamond brush includes at least 30 sets; the fiber brush includes ≤6 sets of 320-mesh first fiber brushes, 4-8 sets of 400-mesh second fiber brushes and ≥4 sets of 600-mesh third fiber brushes arranged sequentially, and the fiber brush includes at least 10 sets.

[0016] Diamond abrasive brushes are generally diamond rubber brushes, primarily used for polishing to reduce the gloss difference between the brick surface and its pits. Because their grit is lower than that of the previous elastic abrasive blocks, they exert greater force on the brick's pits, smoothing out burrs within them. For diamond abrasive brush grit, start with 20-30 sets of 320-grit brushes, then use ≥6 sets of 400-grit brushes. The 400-grit brushes will make the already deburred pits even smoother. Regarding quantity, if the number of diamond rubber brushes is too small, the pits on the brick surface will be difficult to polish. This solution recommends using at least 30 sets of diamond abrasive brushes.

[0017] Fiber brushes are used to repair defects on the previously polished brick surface, such as removing scratches. Specifically, ≤6 sets of 320 mesh, 4-8 sets of 400 mesh, and ≥4 sets of 600 mesh. The number of fiber brushes should also be kept at more than 10 sets to effectively repair defects such as abrasion marks and scratches caused by elastic abrasive blocks and diamond rubber brushes on the brick surface.

[0018] Preferably, the softening wax comprises, by weight percentage, the following raw materials: 3-6% superhydrophilic hybrid polysiloxane, 90-95% deionized water, and 1-3% glycerol. The superhydrophilic polysiloxane content in the softening wax is approximately 3%-6%, and a large amount of deionized water and a small amount of glycerol are added as solvents to adjust its surface drying rate. After applying the softening wax, the gloss is improved to a suitable range of 50-75°, and the anti-slip properties are also enhanced.

[0019] Preferably, by weight percentage, the antifouling wax comprises the following raw materials: 12-24% methyl high-hydrogen silicone oil, 6-14% polyether block amino silicone oil, 5-10% long-chain alkyl silicone oil, and 60-70% organic solvent. The main components of the antifouling wax are methyl high-hydrogen silicone oil, polyether block amino silicone oil, and long-chain alkyl silicone oil, etc., which are prepared by dispersion in organic solvents such as butanol. The solvent can be n-butanol, which allows the antifouling wax to have a suitable surface drying rate and coating uniformity.

[0020] If further adjustments are needed, low-boiling-point solvents such as ethanol and petroleum ether, or high-boiling-point solvents such as DBE and ethylene glycol phenyl ether can be used.

[0021] Preferably, the smoothing wax and the anti-fouling wax are applied to the surface of the marble tile one after the other, and then the smoothing wax and the anti-fouling wax are coated evenly using a grinding head.

[0022] Preferably, the amount of the softening wax applied is 30-40 g / m². 2 The amount of antifouling wax applied is 1-2 g / m³. 2 At the above application rate, the effect on modifying the stain resistance and slip resistance of the tiles is optimal, while the tiles can also maintain a temperature of 50-75°.

[0023] Preferably, the gloss of the marble tile obtained in step S1 is 18-25° by weight percentage; the gloss of the marble tile obtained in step S3 is 50-75°.

[0024] Preferably, the diamond brush is a diamond rubber brush.

[0025] In addition, this invention also proposes a soft-light marble tile, which is prepared by the soft-light marble tile preparation process described in any of the above claims. The soft-light marble tile employs the above-described soft-light marble tile preparation process and has the same beneficial effects as the process itself, which will not be elaborated further here.

[0026] Compared with existing technologies, the soft-gloss marble tiles of this invention have the following beneficial effects: By sequentially treating the tile surface with a high-mesh elastic abrasive block, a low-mesh diamond rubber brush, and a fiber brush, the amount of cutting during the polishing process is reduced. The uneven structure of the tile surface itself is not excessively removed, ensuring the thickness of the glaze layer and reducing the exposure of pores in the glaze layer, which effectively enhances the anti-slip and anti-fouling properties of the marble tiles. Subsequently, a soft-gloss wax is applied to the tile surface, further improving the anti-slip effect and maintaining the tile's gloss at 50-75°, while also providing a soft-gloss finish. Finally, an anti-fouling wax is applied to the tile surface coated with the soft-gloss wax, further enhancing the tile's anti-fouling performance. Attached Figure Description

[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Furthermore, the technical solutions of the various embodiments can be combined with each other, but only if they are feasible for those skilled in the art. If the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0035] A manufacturing process for soft-light marble ceramic tiles includes the following steps:

[0036] S1. The surface of the marble tile is polished sequentially using an elastic grinding block, a diamond grinding brush, and a fiber brush. The gloss of the marble tile obtained after polishing is 18-25°.

[0037] Among them, the elastic abrasive blocks include ≤6 groups of 1500-mesh first elastic abrasive blocks, 4-8 groups of 3000-mesh second elastic abrasive blocks, and 4-8 groups of 5000-mesh third elastic abrasive blocks, with a total of 14-18 groups of elastic abrasive blocks.

[0038] The diamond brush includes 20-30 sets of 320-mesh first diamond brushes and ≥6 sets of 400-mesh second diamond brushes arranged sequentially, with a total of at least 30 sets; the diamond brushes are diamond rubber brushes.

[0039] The fiber brush includes ≤6 groups of 320-mesh first fiber brushes, 4-8 groups of 400-mesh second fiber brushes, and ≥4 groups of 600-mesh third fiber brushes arranged sequentially, and the fiber brush includes at least 10 groups.

[0040] S2. Continue to apply a soft-polish wax to the surface of the marble tile;

[0041] S3. Continue to coat the surface of the marble tile with anti-fouling wax to obtain the soft-gloss marble tile with a gloss of 50-75°.

[0042] The smoothing wax and anti-fouling wax are applied dropwise to the surface of the marble tile. Then, a grinding head is used to evenly coat both waxes. A super-cleaning machine is then used to evenly coat the smoothing wax onto the tile surface, forming a high-hardness coating that fully cures in 3-7 days. The application rate of the smoothing wax is 30-40 g / m². 2 The amount of antifouling wax applied is 1-2 g / m³. 2Applying too little material will result in uneven coating and difficulty in forming a film, while applying too much material will cause it to accumulate. The abrasive used in this solution should be of moderate hardness (this abrasive is produced by Jiangmen Shuangyi Abrasives Co., Ltd., model 2+). If the abrasive is too hard, it will not only be difficult to coat the soft wax into the concave spots of the brick surface, but it will also cause an excessive difference in gloss between the concave spots and other areas of the brick surface, affecting the brick surface effect. If the abrasive is too soft, it will make it difficult for the soft wax to form a film and cure on the brick surface, affecting its weak adhesion to the brick surface and resulting in reduced durability.

[0043] By weight percentage, the smoothing wax comprises the following raw materials: 3-6% superhydrophilic hybrid polysiloxane (produced by Jiangmen Shuangyi Abrasives Co., Ltd.), 90-95% deionized water, and 1-3% glycerol.

[0044] By weight percentage, the antifouling wax comprises the following raw materials: 12-24% methyl high-hydrogen silicone oil, 6-14% polyether block amino silicone oil, 5-10% long-chain alkyl silicone oil, and 60-70% organic solvent.

[0045] For ceramic tiles coated with traditional screen-printed protective glazes, the glaze layer is relatively thin, and the surface contains many closed pores. In traditional processes, when aiming to create a soft-gloss finish, a high-abrasion-weight (small-grit polishing blocks) soft polishing process is often used. This method not only easily polishes through the glaze layer but also exposes the closed pores, reducing its stain resistance. Some researchers have tried to enhance stain resistance by applying anti-fouling wax, but due to the limited adhesion of anti-fouling wax, it is easily damaged during use, resulting in poor durability of the stain-resistant effect.

[0046] Therefore, to improve the anti-slip and anti-fouling properties of ceramic tile products, this solution uses high-mesh elastic abrasive blocks to polish the tile surface, reducing the amount of cutting in the initial polishing process. This gives the tile surface some anti-fouling and anti-slip properties. However, the low cutting amount in the polishing process results in a large number of pits in the microstructure of the tile surface. The difference in gloss between the pits and the tile surface is too large, with the pitted areas being matte and the rest being glossy, causing uneven gloss in some areas. Moreover, the burrs and roughness in the pits cause diffuse reflection, which reduces the clarity of the tile pattern. Overall, this leads to a poor decorative effect, especially after applying a soft-light wax to increase the gloss, this difference in gloss becomes even more obvious. Therefore, a diamond rubber brush is introduced into the polishing process to grind and brush the pits on the tile surface, effectively avoiding the above-mentioned appearance defects. The diamond rubber brush has a relatively small mesh size, and the glaze itself still has a certain degree of anti-fouling and anti-slip effect after polishing.

[0047] The original glaze of conventional marble tile products, such as Figure 1As shown, the fired glaze surface has many uneven textures and is covered with numerous burrs. The gloss of this tile structure is approximately 7-9°. The glaze surface treated with a traditional soft polishing process (directly polishing with small-grit abrasive blocks) is as follows... Figure 2 As shown, due to the large cutting amount, the glaze surface is almost completely polished, the glaze layer becomes thinner, exposing the closed pores and reducing its anti-fouling performance. In contrast, in this solution, the glaze surface polished with high-mesh elastic abrasive blocks is as follows: Figure 3 As shown, the glaze layer suffers minimal loss after polishing, but the surface still retains numerous pits. This gentle polishing process hardly affects the glaze's anti-fouling properties. Continuing with the low-cutting-weight gentle polishing process using a diamond rubber brush, the treated glaze surface appears as... Figure 4 As shown, with a low cutting amount, the burrs in the concave areas of the brick surface are completely brushed away, making the concave areas as smooth as the brick surface, without any difference in gloss. The aesthetic effect of the brick surface is greatly improved, and the glaze surface after polishing still has a certain degree of anti-fouling and anti-slip effect.

[0048] The technical solution of the present invention will be further described in detail below with reference to specific embodiments. It should be understood that the following embodiments are only used to explain the present invention and are not intended to limit the present invention.

[0049] Example 1

[0050] A manufacturing process for soft-light marble ceramic tiles includes the following steps:

[0051] S1. Polish the surface of the marble tile in sequence using an elastic grinding block, a diamond rubber brush, and a fiber brush;

[0052] The elastic abrasive blocks include 5 groups of 1500-mesh elastic abrasive blocks and 7 groups of 2000-mesh elastic abrasive blocks arranged in sequence; the diamond rubber brushes include 26 groups of 320-mesh diamond rubber brushes and 8 groups of 600-mesh diamond rubber brushes arranged in sequence; and the fiber brushes include 5 groups of 400-mesh fiber brushes and 7 groups of 600-mesh fiber brushes arranged in sequence.

[0053] S2. Continue to apply a smoothing wax to the surface of the marble tile, the amount of which is 36g / m². 2 ;

[0054] S3. Continue to apply anti-fouling wax to the surface of the marble tile to obtain the soft-gloss marble tile. The amount of anti-fouling wax applied is 1 g / m². 2 ;

[0055] The smoothing wax comprises, by weight percentage, the following ingredients: 5% superhydrophilic hybrid siloxane, 92% deionized water, and 3% glycerol.

[0056] By weight percentage, the antifouling wax comprises the following raw materials: 16% methyl high-hydrogen silicone oil, 10% polyether block amino silicone oil, 5% long-chain alkyl silicone oil, and 69% organic solvent - n-butanol.

[0057] Comparative Example 1

[0058] In this comparative example, all preparation steps and parameters are the same as in Example 1. The difference lies in the polishing process and the polishing blocks (from low to high mesh). Specifically, 26 sets of 320-mesh elastic grinding blocks, 5 sets of 400-mesh elastic grinding blocks, 15 sets of 600-mesh elastic grinding blocks, 5 sets of 1500-mesh elastic grinding blocks, and 7 sets of 2000-mesh elastic grinding blocks are used to polish the same batch of tiles in sequence.

[0059] Comparative Example 2

[0060] In this comparative example, all preparation steps and parameters are the same as in Example 1. The difference lies in the polishing process (the order is changed compared to Example 1). Specifically, 26 sets of 320-mesh diamond rubber brushes, 8 sets of 600-mesh diamond rubber brushes, 5 sets of 400-mesh fiber brushes, 7 sets of 600-mesh fiber brushes, 5 sets of 1500-mesh elastic abrasive blocks, and 7 sets of 2000-mesh elastic abrasive blocks are used to polish the same batch of ceramic tiles in sequence.

[0061] The soft-light marble tiles prepared in Example 1 and Comparative Examples 1-2 were subjected to performance testing. The specific test results are shown in the table below:

[0062]

[0063] Note: 1. Tile stain resistance testing process: After drawing on a fixed position on the tile surface with a blue marker, wipe it with alkaline sand. If no blue ink residue is left after three consecutive tests, it is considered qualified. In the stain resistance level, qualified > slightly stained > heavily stained. In the table above, "before waxing" refers to tiles that have not been waxed after polishing, and "after waxing" refers to tiles that have been waxed after polishing.

[0064] 2. Durability test: The tile products were tested by stomping on them using a simulated trampling device (simulating the pressure and friction of trampling). After 5 hours of continuous testing, the tile surface was observed for any obvious shoe prints or shadows.

[0065] 3. According to Appendix M of GB4100, the anti-slip properties of ceramic tiles should be tested, and the static friction coefficient of the tiles should be ≥0.5.

[0066] 4. Detection of adhesive residue: Apply 502 glue to the obtained tile, remove it after 24 hours, and observe whether there is any obvious adhesive residue on the tile surface.

[0067] 5. Check for the presence or absence of grid pattern: After stacking the obtained ceramic tile products for 8 hours, observe whether there is a grid pattern on the tile surface.

[0068] 6. Gloss testing was conducted using a gloss meter. Slight differences in gloss may exist among tiles from the same batch. The gloss was tested on 10 tiles that had been polished and waxed in the examples and comparative examples. Therefore, the obtained gloss values ​​are range values.

[0069] The test results in the table above show that the gloss of the soft-light marble tiles prepared in this method is within the range of 50-75°, exhibiting a good soft-light effect. Simultaneously, the marble tiles demonstrate good anti-slip, stain-resistant, and durability properties. The test results of Example 1 and Comparative Example 1 show that the glaze of Example 1 has better stain-resistant performance, with even better results after applying wax. The tile glaze itself possesses excellent anti-slip properties without damaging its uneven structure. In Example 1, after the uneven structure of the tile surface is polished to a smooth finish before applying wax, the 502 glue cannot adhere tightly to the small burrs on the uneven areas, allowing the 502 glue to be completely removed without residue, thus avoiding glue marks.

[0070] When the polishing cutting amount in Comparative Example 1 increases, the uneven structure is almost completely polished away, the anti-slip performance will decrease significantly, and the stain resistance will also be poor.

[0071] The test results of Example 1 and Comparative Example 2 show that the appearance of Comparative Example 2 is not as good as that of Example 1. Since the low-mesh fiber brush is actually used to repair the appearance defects of the tile surface polished by the elastic abrasive block, swapping the positions of the fiber brush and the elastic abrasive block in the polishing process will greatly reduce the appearance of the tile surface. In addition, the anti-slip and anti-fouling effects of the tile are also reduced. At the same time, the polishing marks produced by polishing will make it easier to trap and absorb dirt when the anti-fouling performance is tested, which will have a significant impact on the anti-fouling performance. These polishing marks make the wax solution have a certain degree of instability when it is bonded to the tile surface, which will also have a certain impact on the durability of the tile.

[0072] Example 2

[0073] In this embodiment, all preparation steps and parameters are the same as in Example 1, except for the polishing process.

[0074] Specifically, the elastic abrasive blocks include 5 groups of 1500-mesh elastic abrasive blocks, 3 groups of 3000-mesh elastic abrasive blocks, and 11 groups of 5000-mesh elastic abrasive blocks arranged in sequence; the diamond rubber brushes include 15 groups of 320-mesh diamond rubber brushes and 15 groups of 400-mesh diamond rubber brushes arranged in sequence; and the fiber brushes include 3 groups of 320-mesh fiber brushes, 5 groups of 400-mesh fiber brushes, and 3 groups of 600-mesh fiber brushes arranged in sequence.

[0075] The soft-light marble ceramic tile prepared in Example 2 was subjected to performance testing. The specific test results are shown in the table below:

[0076]

[0077]

[0078] As shown in the table above, based on the test results of Example 1 and Example 2, the anti-slip effect of Example 2 is slightly better than that of Example 1. In addition, it should be noted that, in terms of appearance, the elastic abrasive block combination of Example 1 cuts less on the brick surface, so the brick surface retains many uneven structures, the gloss is lower after waxing, and there are more fine pits. The appearance of the brick surface is worse than that of Example 2 (among which, the brick surface of Example 1 has more fine pits, while the brick surface of Example 2 has fewer fine pits).

[0079] Example 3

[0080] In this embodiment, all preparation steps and parameters are the same as in Example 1, except for the polishing process.

[0081] Specifically, the elastic abrasive blocks include 5 sets of 1500-mesh elastic abrasive blocks, 4 sets of 3000-mesh elastic abrasive blocks, and 6 sets of 5000-mesh elastic abrasive blocks arranged in sequence, for a total of 15 sets of elastic abrasive blocks; the diamond rubber brushes include 23 sets of 320-mesh diamond rubber brushes and 7 sets of 400-mesh diamond rubber brushes arranged in sequence, for a total of 30 sets of diamond rubber brushes; and the fiber brushes include 6 sets of 320-mesh fiber brushes, 4 sets of 400-mesh fiber brushes, and 5 sets of 600-mesh fiber brushes arranged in sequence, for a total of 15 sets of fiber brushes.

[0089] By weight percentage, the antifouling wax comprises the following raw materials: 18% methyl high-hydrogen silicone oil, 10% polyether block amino silicone oil, 8% long-chain alkyl silicone oil, and 64% organic solvent n-butanol.

[0090] Example 5

[0091] A manufacturing process for soft-light marble ceramic tiles includes the following steps:

[0092] S1. Polish the surface of the marble tile in sequence using an elastic grinding block, a diamond rubber brush, and a fiber brush;

[0093] The elastic abrasive blocks include 4 sets of 1500-mesh elastic abrasive blocks, 5 sets of 3000-mesh elastic abrasive blocks, and 5 sets of 5000-mesh elastic abrasive blocks arranged in sequence, for a total of 14 sets of elastic abrasive blocks; the diamond rubber brushes include 29 sets of 320-mesh diamond rubber brushes and 6 sets of 400-mesh diamond rubber brushes arranged in sequence, for a total of 35 sets of diamond rubber brushes; the fiber brushes include 3 sets of 320-mesh fiber brushes, 4 sets of 400-mesh fiber brushes, and 4 sets of 600-mesh fiber brushes arranged in sequence, for a total of 11 sets of fiber brushes.

[0094] S2. Continue to apply a smoothing wax to the surface of the marble tile, the amount of which is 35g / m². 2 ;

[0095] S3. Continue to apply anti-fouling wax to the surface of the marble tile to obtain the soft-gloss marble tile. The amount of anti-fouling wax applied is 1 g / m². 2 .

[0096] By weight percentage, the smoothing wax comprises the following ingredients: 6% superhydrophilic hybrid siloxane, 91% deionized water, and 3% glycerol.

[0097] By weight percentage, the antifouling wax comprises the following raw materials: 22% methyl high-hydrogen silicone oil, 6% polyether block amino silicone oil, 6% long-chain alkyl silicone oil, and 66% organic solvent n-butanol.

[0098] The soft-light marble tiles prepared in Examples 3-5 were subjected to performance testing. The specific test results are shown in the table below:

[0099]

[0100]

[0101] As shown in the table above, based on the test results of Examples 1 and 3, the anti-slip performance of the ceramic tile has been further improved, and the gloss can be maintained within the range of 55-75°.

[0102] As can be seen from the test results of Examples 3-5, the tiles of this scheme, after the above polishing process, have good anti-fouling effect, anti-slip effect and surface appearance (the tiles of Examples 3-5 have fewer fine pits than those of Example 2), and the static friction coefficient can be maintained above 0.79, while the gloss is maintained at 55-75°.

[0103] Comparative Example 3

[0104] In this comparative example, all preparation steps and parameters are the same as in Example 4. The difference is that diamond rubber brushes were not used for polishing in this comparative example. That is, the 22 sets of 320-mesh diamond rubber brushes and the 8 sets of 400-mesh diamond rubber brushes that were set in sequence were removed in the polishing process.

[0105] Comparative Example 4

[0106] In this comparative example, all preparation steps and parameters are the same as in Example 4. The difference is that in this comparative example, the diamond rubber brushes are replaced with elastic grinding blocks for polishing. Specifically, the 22 sets of 320-mesh diamond rubber brushes and the 8 sets of 400-mesh diamond rubber brushes are replaced with the 22 sets of 320-mesh elastic grinding blocks and the 8 sets of 400-mesh elastic grinding blocks.

[0107] The soft-light marble tiles prepared in Comparative Examples 3-4 were subjected to performance testing. The specific test results are shown in the table below:

[0108]

[0109]

[0110] As shown in the table above, based on the test results of Example 4 and Comparative Example 3, the impact on the anti-fouling and durability properties of the brick is relatively small when it is not polished with a diamond rubber brush. However, many dark spots formed by the accumulation of dark pits will appear on the brick surface, which seriously affects the appearance of the brick surface. At the same time, since it is not treated with a diamond rubber brush, the burrs at the pits are not tightly bonded to the wax, which easily produces many micropores, making it easy to trap dirt, and the anti-slip performance of the tile is also reduced.

[0111] As can be seen from the test results of Example 4 and Comparative Example 4, replacing the diamond rubber brush with an elastic abrasive block of the same mesh size will cause the brick surface to be over-polished. This will not only cause a large number of polishing marks on the brick surface, affecting its anti-fouling performance, durability and anti-slip performance, but also increase the gloss of the brick surface, making the ceramic tile lack a soft gloss effect.

[0112] Example 6

[0113] In this embodiment, all preparation steps and parameters are the same as in Example 4, except that the amount of polishing wax and anti-fouling wax applied is different, as shown in the table below:

[0114] <![CDATA[Soft light wax application amount (g / m 2 )]]> <![CDATA[Anti-fouling wax application amount (g / m 2 )]]> Example 4 40 1.5 Example 6-1 30 1 Example 6-2 33 1.2 Example 6-3 36 1.7 Example 6-4 39 2

[0115] Comparative Example 5

[0116] In this comparative example, all preparation steps and parameters are the same as in Comparative Example 1, except that the application amounts of the smoothing wax and antifouling wax are different; the application amount of the smoothing wax is 36 g / m². 2 The application rate of antifouling wax is 14 g / m². 2 .

[0117] The soft-light marble tiles prepared in Example 6 and Comparative Example 5 were subjected to performance testing. The specific test results (after waxing) are shown in the table below:

[0118]

[0119] As can be seen from the test results of Example 6 in the table above, the soft-light marble tiles of this solution achieve better performance with a relatively small amount of anti-fouling wax applied (only 1-2 g / m²). 2 The resulting tiles also have good stain resistance.

[0120] The test results of Comparative Example 5 show that for the tiles obtained by the conventional polishing method in Comparative Example 1, the amount of anti-fouling wax needs to be increased to 14 g / m². 2 Only by using this amount can a good immediate stain-resistant effect be obtained. If the amount is less than this, the stain resistance of the tile will be slightly or severely stained, and the durability of the tile will still be poor.
