[0002] In recent years, as the decoration style has changed from the past magnificent to the present deep low-key, luxurious but not flashy, the mainstream trend of ceramic products has gradually tended to the plain matte, plain concave and convex texture, a large category of plain and matte products. It has the characteristics of non-glare and no reflection imaging, which is more in line with the aesthetic needs of today's customers. At the same time, this type of brick is also labeled as hiding dirt, hiding dust, and difficult to clean. During the sintering process of ceramic tiles, the surface glaze will form a micro-continuous peak and valley structure, which can cause light scattering, and the depressions are also prone to dirt accumulation and difficult to clean. There are roughly two types of matte bricks on the market. One is that after sintering, it is lightly polished and softly polished to reduce the drop of the peak and valley structure, and a matte brick with a gloss of about 10° is prepared; the other is sintered into a matte brick with a gloss of about 10° and a warm feel through a special glaze (gold velvet, matte glaze, candy glaze, skin glaze, etc.).

[0003] However, the above matte tiles all have poor anti-graffiti performance and can hide dirt and dust. To this end, we provide a matte anti-slip, anti-fouling and easy-to-clean marble tile and a preparation method thereof. Summary of the invention

[0058] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments, and the contents mentioned in the implementation modes are not intended to limit the present invention.

[0059] In the actual development and production of ceramic tiles, we found that through observation under a microscope, the poor anti-fouling performance of matte tiles is mainly due to the presence of micron-level pores and microscopic continuous peak-valley structures on the glaze surface. On the market, similar methods have been used to develop some matte anti-fouling wax water to fill the pores and peak-valley structures on the brick surface to improve its anti-fouling performance. However, once the peak-valley structure of the brick surface is filled, its surface roughness decreases, resulting in a small static friction coefficient on the brick surface and reduced anti-slip performance.

[0060] To this end, we have developed a new type of primer wax water and intermediate wax water. By applying the primer wax water and intermediate wax water to the semi-finished ceramic tiles in sequence, the surface of the finished ceramic tiles can reduce the difference between the peaks and valleys but will not completely fill the peak-valley structure, so that the glossiness of the tile surface is increased and a certain anti-slip performance is maintained. At the same time, the pits on the surface are too shallow to meet the anti-fouling performance requirements. Moreover, after the finished ceramic tiles are continuously stepped on, the static friction coefficient of the tile surface increases. Analysis shows that the primer wax water has a certain flexibility and plastic deformation after film formation, and the difference between the peak-valley structure is increased under the action of external force, so that the anti-slip performance is improved. However, the anti-fouling performance of the sample tiles that have been stepped on does not meet the standards. Therefore, on this basis, a surface wax water is further developed to solve the problems of increased glossiness and dirt sticking. At the same time, we found that using the matte anti-fouling wax on the market as the top coating wax will have durability problems, and when the height difference of the peak-to-valley structure reaches 10um, visible dirt will be stuck, and it cannot be cleaned with water. The hydrophobicity of the surface prevents water from infiltrating the pits on the brick surface and cannot remove the dirt in the pits. For this reason, we have developed a new type of primer wax, middle wax, and top coating wax. When the top coating wax is superimposed on the middle layer, it has the effect of reducing gloss and facilitating cleaning;

[0061] After coating the finished ceramic tiles with the primer layer formed by the primer wax water, the middle layer formed by the intermediate wax water, and the top layer formed by the top wax water described in this application, a stepping test is carried out. The stepped-on samples are then tested for pollution resistance according to the national standard "GB / T3810.14-2016" for pollution resistance of ceramic tiles. The pollutants can be directly rinsed off with water to meet the level 5 pollution resistance standard.

[0062] In addition, the adhesion and superposition of the base coat, the middle coat, and the top coat make the finished ceramic tile have both anti-fouling and anti-slip properties, but there is a problem of unstable glossiness of the tile surface, which affects the aesthetic appearance. After analysis, it was found that the base coat wax water did not fill the micron-level pores sufficiently and the wax water was not evenly polished. Therefore, we adjusted the preparation method of ceramic tiles, and used polishing to apply the base coat wax water to the bottom layer of the tile surface, and stabilized the glossiness at about 30°. The 30° glossiness exceeds the effect of the middle wax water on the glossiness, avoiding the middle wax water from affecting the appearance of the tile surface; then the middle wax water with good plastic deformation is applied as the middle layer on the tile surface, and finally the top coat wax water with good scattering and hydrophilicity is applied as the top coat on the top layer, to obtain matte ceramic tiles with good appearance transparency, good anti-fouling and good anti-slip properties.

[0063] To this end, we provide a matte anti-slip, anti-fouling and easy-to-clean marble tile and a preparation method thereof.

[0236] Step 2: According to the conventional method, the ceramic tiles out of the kiln are lightly polished using four processes in sequence: rough polishing (3000 fineness elastic module), fine polishing (5000 fineness elastic module), fine polishing (6000 fineness elastic module), and brush polishing (200 fineness soft fiber) to obtain semi-finished ceramic tiles with a glossiness of 10-12°.

[0237] Performance testing:

[0238] 1. The base wax prepared in Examples 1-5 was tested for adhesion performance, the middle wax toughness (according to the paint film impact resistance test standard: GB / T1732-1993 "Paint film impact resistance determination method"), and the top wax was tested for scattering and hydrophilicity. The relevant results are summarized in the following Table 1:

[0239] Table 1

[0240]

[0241] It can be seen that in Examples 1-5, the surface wax layer has a very high adhesion level, reaching 5B; the surface wax layer also meets the qualified requirements in the toughness test; at the same time, the surface wax layer reaches 19-26° in scattering, and the hydrophilicity is less than 50°.

[0242] 2. The marble ceramic tiles prepared in Examples 6-10 and Comparative Examples 1-3 were tested for performance, and the relevant results are summarized in Table 2 below;

[0243] Among them: stain resistance is tested according to the standard "GB / T3810.14-2016";

[0244] Table 2

[0245]

[0246] from Figure 1 It can be seen that on the ceramic tile of Example 6, the wax water composition is initially applied evenly, with a smooth outline and no obvious peak-valley structure; Figure 2 In the test, the surface roughness of the ceramic tile of Example 6 increases after being stepped on, and its profile changes from smooth to rough. It can be seen that the surface wax layer has certain plasticity and flexibility. As can be seen from Table 2, the ceramic tiles prepared in Examples 6 to 10 can be erased three times in the anti-graffiti test, with a dry static friction coefficient of 0.69-0.70, a stain resistance of level 5, and a glossiness of 15-18°; in the simulated stepping test: the anti-graffiti test can be erased three times after stepping on, and the dry static friction coefficient after stepping on is 0.71-0.73.

[0247] Comparative Example 1, combined Figure 3 It can be seen that when the ceramic tile lacks the filling of the primer, the middle layer cannot fill the position of the larger hornet's nest. The primer has a filling effect on the pores on the brick surface, making the brick surface less likely to absorb dirt and having better flatness. In the anti-graffiti test, the ceramic tile prepared in Comparative Example 1: it slightly absorbed dirt twice, and the third time it obviously absorbed dirt and could not be wiped off. The dry static friction coefficient is 0.69-0.70, the stain resistance reaches level 5, and the gloss is 15-18°; in the simulated trampling test: the anti-graffiti test after trampling has two slight dirt absorptions, and the third time it obviously absorbed dirt and could not be wiped off.

[0248] The ceramic tile prepared in Comparative Example 2, in the anti-graffiti test: can be erased three times, the dry static friction coefficient is 0.69-0.70, the stain resistance reaches level 5, and the gloss is 18-20°; in the simulated trampling test: the anti-graffiti test after trampling can not be erased three times, and the dry static friction coefficient after trampling is reduced to 0.60-0.63. Figure 4 It can be seen that the surface of the ceramic tile obtained by omitting the middle layer of wax water becomes smooth, and the dry static friction coefficient is lower than 0.65, which makes the anti-slip performance worse than that of general matte tiles.

[0249] The ceramic tile prepared in comparative example 3 can be erased three times in the anti-graffiti test, with a dry static friction coefficient of 0.69-0.70, a stain resistance of level 5, and a glossiness of 35-40°; in the simulated trampling test, the anti-graffiti test can be erased three times after trampling, and the dry static friction coefficient after trampling is 0.71-0.73, and it is found that the ceramic tile has a high glossiness. Figure 5 It can be seen that the ceramic tiles obtained by omitting the surface wax water have a glossiness that exceeds the standard of matte tiles.

[0250] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention may also be implemented in other ways. Any obvious replacement without departing from the concept of the present invention is within the protection scope of the present invention.
