[0002] The antique brick is a kind of decoration material, and the surface aging process makes the space look like a retro atmosphere. The antique brick refers to a glazed brick, which is composed of a body and a glaze. The glaze is applied on the surface of the ceramic tile body and is formed by high-temperature and high-pressure firing. The antique brick is named because of the intentionally polished and irregular edges of the ceramic tile surface, which causes the appearance of years of erosion, and creates a sense of history and naturalness.

[0003] However, the antique brick intentionally has wear marks and rough textures, and dust and oil stains are easily accumulated in the gullies, which affects the overall appearance of the antique brick, and also easily breeds microorganisms such as bacteria, mold, and E. coli, which may pose a threat to human health.

The remaining steps are the same as those of Example 2.

[0040] Comparative Example 2:

[0041] The preparation process of the high-slip-resistance antique tile with concave-convex of Comparative Example 2 is different from that of Example 2 in step (2). Step (2) is modified as follows: 3-aminopropyltrimethoxysilane and isopropyl alcohol are mixed at a mass ratio of 1:10, and the pH is adjusted to 5 with 0.1 mol / L acetic acid aqueous solution to prepare a surface treatment solution; the antique tile substrate is soaked in the surface treatment solution, and is placed at 90℃ for 6 h, taken out, washed with deionized water for 7 times, and dried at 45℃ for 23 h to prepare a pre-modified antique tile; 5,7-dihydroxyflavone and acetone are uniformly mixed at a mass ratio of 1:5 to prepare a flavone solution; the pre-modified antique tile is soaked in the flavone solution, and is placed at 50℃ for 12 h, taken out, washed with ethanol for 4 times, and vacuum dried at 45℃ for 23 h to prepare an antique tile. The remaining steps are the same as those of Example 2.

[0042] Comparative Example 3:

[0043] The preparation process of the high-slip-resistance antique tile with concave-convex of Comparative Example 3 is different from that of Example 2 in that step (2) is not modified. The remaining steps are the same as those of Example 2.

[0044] Test Example 1:

[0045] Slip resistance test: the antique tiles prepared in each example and comparative example are soaked in deionized water for 2 h, and then the pendulum value is tested by using a pendulum friction coefficient tester of SK1564. The results are shown in Table 1.

[0046] Table 1 Slip resistance test results

[0047]

[0048] From the comparison of the experimental data in Table 1, it can be found that the antique bricks prepared by the present application have good slip resistance.

[0049] Test Example 2:

[0050] Antibacterial test: According to the standard JC / T897-2014, Escherichia coli and Staphylococcus aureus were selected for antibacterial test, and the antibacterial rate was calculated.

[0051] Stain resistance test: The antique bricks of each example and the comparative example were subjected to 10 min continuous drop rolling test (glycerol 45%) and mud pouring (mud 45 wt%) test, and the water contact angle and mud contact angle were tested. The results are shown in Table 2.

[0052] Table 2 Antibacterial and stain resistance test results

[0053]

[0054] From the comparison of the experimental data in Table 2, it can be found that the antique bricks prepared by the present application have good antibacterial and stain resistance.

[0055] From the comparison of the experimental data of Examples 1, 2, 3 and Comparative Example 1 in Table 2, it can be found that the antibacterial rates of Examples 1, 2 and 3 are large. The difference between Comparative Example 1 and the examples is that no zwitterion containing quaternary ammonium salt is formed by the reaction of 1,3-propanesultone and Schiff base. This shows that the quaternary ammonium salt can be adsorbed on the surface of the bacterial cell membrane, and through electrostatic attraction with the negatively charged components on the cell membrane, the permeability of the cell membrane is changed, thereby achieving antibacterial effect.

[0056] From the comparison of the experimental data of Examples 1, 2, 3 and Comparative Example 2, it can be found that the contact angles of Examples 1, 2 and 3 are large. The difference between Comparative Example 2 and the examples is that no perfluoro group is introduced on the surface of the material by the reaction of ketone group and amino group. This shows that due to the low surface energy characteristics of perfluoro group, it is difficult for dirt to adhere to the surface of the antique brick. And because of the strong electronegativity of fluorine atom, the electron cloud in carbon-fluorine bond is biased towards fluorine atom, making carbon atom positively charged, which overall shows hydrophobicity. This makes the surface of the antique brick easy to be washed by water flow, reducing the adhesion and growth of fouling organisms, thereby achieving stain resistance effect.

[0057] Test Example 3:

[0058] Coating durability test: The modification of step 2 was applied to the surface of ordinary flat glass, and the sample was irradiated under fluorescent ultraviolet lamp UV-A340 for 15 days to observe whether the coating was yellow. The results are shown in Table 3.

[0059] Table 3 Coating durability test results

[0060]

[0061] From the comparison of the experimental data in Table 3, it can be found that the coating of the antique brick prepared by the present application has aging resistance.

[0062] From the comparison of the experimental data in Table 3, it can be found that the coating of the antique brick prepared by the present application has aging resistance.
