Description

Technical Field

[0001] This invention relates to the field of building materials, specifically to a highly slip-resistant antique-style brick with an uneven surface and its preparation process. Background Technology

[0002] Antique tiles, as a type of decoration material, have an aged appearance that gives the space a retro feel. Antique tiles refer to glazed tiles, which consist of two parts: the body and the glaze. Glaze is applied to the surface of the tile body and then fired at high temperature and pressure. They are named for the intentional polishing and irregular edges of the tile surface to create an appearance that looks like it has been eroded by time, thus creating a sense of history and nature.

[0003] However, antique-style tiles are intentionally designed with wear marks and rough textures, making it easy for dust and oil stains to accumulate in the grooves, affecting the overall aesthetics of the tiles. They also easily breed bacteria, mold, E. coli, and other microorganisms, which may pose a threat to human health. Therefore, this application introduces a highly slip-resistant antique-style tile with an uneven surface and antibacterial properties, as well as its preparation process. Summary of the Invention

[0004] The purpose of this invention is to provide a highly slip-resistant antique-style brick with an uneven surface and its preparation process, so as to solve the problems existing in the prior art.

[0005] A high-slip anti-slip antique brick with an uneven surface is prepared by reacting an antique brick matrix sequentially with 3-aminopropyltrimethoxysilane, 5,7-dihydroxyflavone, 1H,1H-perfluorooctylamine and 1,3-propanesulfonic acid lactone.

[0006] The antique brick base is made by mixing sodium feldspar, quartz, calcite, zinc oxide, barium carbonate, deionized water, water glass and American fairy water, glazing it on the surface of the brick blank, and firing it.

[0007] The brick blank is made by molding, firing, and pressing ferrochrome waste slag, fly ash, clay, quartz sand, clay powder, and red clay powder.

[0008] A manufacturing process for a highly slip-resistant antique-style brick with an uneven surface, the manufacturing process mainly includes the following steps:

[0009] (1) Sodium feldspar, quartz, calcite, zinc oxide, barium carbonate, deionized water, water glass and American fairy water are mixed in a mass ratio of 48~51:18~19:7~8:4~6:6~7:78~80:0.5~0.7:0.15~0.25 and ball-milled at 300~500r / min for 18~22min. The brick blank is glazed by dipping. The temperature is raised to 1110~1130℃ at a uniform rate within 55~65min, held for 35~45min, and cooled to room temperature to obtain the antique brick base.

[0010] (2) The functionalized antique bricks are soaked in 1,3-propanesulfonic acid lactone at 35~37℃ for 20~30s, taken out, and placed at 85~95℃ for 4~5h under nitrogen protection. They are then washed with ether 3~5 times and vacuum dried at 40~50℃ for 22~24h to obtain the antique bricks.

[0011] As an optimization, the brick blank in step (1) is made by mixing 300-400 mesh ferrochrome slag, 400 mesh fly ash, 400-500 mesh clay, 200-300 mesh quartz sand, 400-500 mesh clay powder, 400-500 mesh red clay powder, and deionized water in a mass ratio of 28-32:28-32:38-42:8-12:14-16:18-20:11-12, stirring at 200-300 r / min for 14-16 min, and letting it stand under sealed conditions for 22-26 h. Under 5 MPa, the alumina powder is pressed into shape using a 25×15cm concave-convex mold, dried at 95~105℃ for 22~26h, placed on a shelf containing alumina powder, and heated at a uniform rate to 1110~1130℃ within 55~65min, held for 8~12min, heated to 1130~1150℃, held for 18~22min, heated to 1150~1170℃, held for 28~32min, heated to 1170~1190℃, held for 38~42min, and cooled to room temperature to obtain the product.

[0012] As an optimization, the manufacturer of the 25×15cm concave-convex mold is Hebei Hongxiang Mold Manufacturing Co., Ltd.

[0013] As an optimization, the functionalized antique brick in step (2) is prepared by immersing the modified antique brick in a surface modification liquid, letting it stand at 68~72℃ for 12~14h, taking it out, washing it with methanol 3~5 times, and vacuum drying it at 40~50℃ for 22~24h.

[0014] As an optimization, the surface modification liquid is prepared by mixing 1H,1H-perfluorooctylamine and methanol at a mass ratio of 1:80~90.

[0015] As an optimization, the modified antique brick is prepared by soaking the pre-modified antique brick in a flavonoid solution, letting it stand at 45~55℃ for 11~13h, taking it out, washing it with ethanol 3~5 times, and vacuum drying it at 40~50℃ for 22~24h.

[0016] As an optimization, the flavonoid solution is prepared by uniformly mixing 5,7-dihydroxyflavone and acetone at a mass ratio of 1:4~6.

[0017] As an optimization, the pre-modified antique brick is prepared by immersing the antique brick substrate in a surface treatment solution, letting it stand at 85~95℃ for 5~7 hours, taking it out, washing it with deionized water 6~8 times, and drying it at 40~50℃ for 22~24 hours.

[0018] As an optimization, the surface treatment solution is prepared by mixing 3-aminopropyltrimethoxysilane and isopropanol at a mass ratio of 1:8~12, and adjusting the pH to 4~6 with a 0.1mol / L aqueous acetic acid solution.

[0019] As an optimization, the surface finishing mechanism for antique-style bricks is as follows:

[0020]

[0021]

[0022]

[0023] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0024] In preparing high-slip anti-slip antique-style bricks with an uneven surface, the present invention involves molding and firing ferrochrome slag, fly ash, clay, quartz sand, clay powder, and red clay powder to obtain a brick blank; mixing sodium feldspar, quartz, calcite, zinc oxide, barium carbonate, deionized water, water glass, and American celery, glazing the surface of the brick blank, and firing to obtain an antique-style brick matrix; and reacting the antique-style brick matrix sequentially with 3-aminopropyltrimethoxysilane, 5,7-dihydroxyflavone, 1H,1H-perfluorooctylamine, and 1,3-propanesulfonic acid lactone to obtain a high-slip anti-slip antique-style brick with an uneven surface.

[0025] First, chromium slag, fly ash, clay, quartz sand, clay powder, and red clay powder are molded, fired, and used to obtain brick blanks. Then, sodium feldspar, quartz, calcite, zinc oxide, barium carbonate, deionized water, water glass, and American celery are mixed and glazed on the surface of the brick blanks, and fired to obtain the antique brick base. Finally, industrial waste such as chromium slag and fly ash are mixed and glazed. Sodium feldspar in the glazing material, as a silicate, reacts with the silicate in the glaze layer when acidic substances (such as acetic acid) come into contact with it, dissolving microscopic silica particles and forming millions of nanoscale grooves. These grooves significantly increase the coefficient of friction by increasing the contact area between the shoe sole and the ground, thus achieving an anti-slip effect.

[0026] Secondly, the antique brick matrix is ​​reacted sequentially with 3-aminopropyltrimethoxysilane, 5,7-dihydroxyflavone, 1H,1H-perfluorooctylamine, and 1,3-propanesulfonic acid lactone to prepare a highly anti-slip antique brick with an uneven surface. The reaction of the antique brick matrix with 3-aminopropyltrimethoxysilane and 5,7-dihydroxyflavone introduces flavonoids onto the material surface through the reaction of amino groups with alkenes. Flavonoids have strong antioxidant properties, preventing the generation and reducing the activity of free radicals, thereby combating oxidative damage to the organic coating on the surface of the antique brick and extending the coating's service life. Then, it is reacted with 1H,1H-perfluorooctylamine... The reaction involves the introduction of perfluorooctyl groups through the reaction of ketone and amino groups. Due to their low surface energy, dirt is difficult to adhere to the surface of antique bricks. Furthermore, due to the strong electronegativity of fluorine atoms, the electron cloud in the carbon-fluorine bond is biased towards the fluorine atom, making the carbon atom positively charged. Overall, the reaction is hydrophobic, which makes it easy for surface contaminants and dirt to be washed away by water flow, reducing the adhesion and growth of contaminants and thus achieving a stain-resistant effect. Finally, the reaction with 1,3-propanesulfonic acid lactone allows the quaternary ammonium salt to be adsorbed onto the surface of bacterial cell membranes. Through electrostatic attraction, it attracts negatively charged components on the cell membrane, altering the permeability of the cell membrane and thus achieving an antibacterial effect.

[0040] Comparative Example 1:

[0041] The difference between the preparation process of the high anti-slip antique brick with textured surface in Comparative Example 1 and that in Example 2 lies in the difference in step (2). Step (2) is modified as follows: 3-aminopropyltrimethoxysilane and isopropanol 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 obtain a surface treatment solution; the antique brick substrate is immersed in the surface treatment solution, left to stand at 90°C for 6 hours, taken out, washed 7 times with deionized water, and dried at 45°C for 23 hours to obtain a pre-modified antique brick; 5,7-dihydroxy Flavonoids and acetone were mixed evenly at a mass ratio of 1:5 to prepare a flavonoid solution. The pre-modified antique bricks were immersed in the flavonoid solution and allowed to stand at 50°C for 12 hours. After removal, they were washed four times with ethanol and vacuum dried at 45°C for 23 hours to obtain modified antique bricks. 1H,1H-perfluorooctylamine and methanol were mixed evenly at a mass ratio of 1:85 to prepare a surface modification solution. The modified antique bricks were immersed in the surface modification solution and allowed to stand at 70°C for 13 hours. After removal, they were washed four times with methanol and vacuum dried at 45°C for 24 hours to obtain antique bricks. The remaining steps were the same as in Example 2.

[0042] Comparative Example 2:

[0043] The difference between the preparation process of the textured, high-slip anti-slip antique brick in Comparative Example 2 and Example 2 lies in step (2). Step (2) is modified as follows: 3-aminopropyltrimethoxysilane and isopropanol are mixed at a mass ratio of 1:10, and the pH is adjusted to 5 with a 0.1 mol / L acetic acid aqueous solution to obtain a surface treatment solution; the antique brick substrate is immersed in the surface treatment solution, left to stand at 90°C for 6 hours, removed, washed 7 times with deionized water, and dried at 45°C for 23 hours to obtain a pre-modified antique brick; 5,7-dihydroxyflavone and acetone are mixed evenly at a mass ratio of 1:5 to obtain a flavonoid solution; the pre-modified antique brick is immersed in the flavonoid solution, left to stand at 50°C for 12 hours, removed, washed 4 times with ethanol, and vacuum dried at 45°C for 23 hours to obtain the antique brick. The remaining steps are the same as in Example 2.

[0044] Comparative Example 3:

[0045] The difference between the preparation process of the textured, high-slip anti-slip antique-style brick in Comparative Example 3 and Example 2 is that step (2) is not modified. The remaining steps are the same as in Example 2.

[0046] Test Example 1:

[0047] Anti-slip test: The antique-style bricks prepared in each embodiment and the comparative example were soaked in deionized water for 2 hours, and the pendulum value was tested using an SK1564 pendulum friction coefficient measuring instrument. The results are shown in Table 1.

[0048] Table 1. Anti-slip test results

[0049]

[0050] A comparison of the experimental data in Table 1 shows that the antique-style bricks prepared by this invention have good anti-slip properties.

[0051] Test Example 2:

[0052] Antibacterial test: According to the JC / T897-2014 standard, Escherichia coli and Staphylococcus aureus were selected for antibacterial test, and the antibacterial rate was calculated.

[0053] Anti-fouling test: The antique bricks prepared in each example and the comparative example were subjected to a 10-minute continuous droplet rolling test (glycerol 45%) and a mud pouring test (mud 45wt%) to test the water contact angle and mud contact angle. The results are shown in Table 2.

[0054] Table 2 Results of antibacterial and antifouling tests

[0055]

[0056] A comparison of the experimental data in Table 2 shows that the antique-style bricks prepared by this invention have good antibacterial and anti-fouling capabilities.

[0057] A comparison of the experimental data from Examples 1, 2, 3 and Comparative Example 1 in Table 2 reveals that Examples 1, 2, and 3 exhibit higher antibacterial rates. The difference between Comparative Example 1 and the Examples lies in the absence of the formation of zwitterions containing quaternary ammonium salts through the reaction of 1,3-propanesulfonic acid lactone with Schiff base. This indicates that quaternary ammonium salts can adsorb onto the surface of bacterial cell membranes and attract negatively charged components on the cell membrane through electrostatic interactions, thereby altering the permeability of the cell membrane and achieving an antibacterial effect.

[0058] A comparison of the experimental data from Examples 1, 2, 3 and Comparative Example 2 reveals that Examples 1, 2, and 3 exhibit larger contact angles. The difference between Comparative Example 2 and the Examples lies in the absence of perfluorinated groups on the material surface through the reaction of ketone and amino groups. This indicates that the low surface energy of perfluorinated groups makes it difficult for dirt to adhere to the surface of antique bricks. Furthermore, due to the strong electronegativity of fluorine atoms, the electron cloud in the carbon-fluorine bond is biased towards the fluorine atom, making the carbon atom positively charged and exhibiting overall hydrophobicity. This makes it easy for surface contaminants and dirt to be washed away by water flow, reducing the adhesion and growth of contaminants, thereby achieving a dirt-proof effect.

[0059] Test Example 3:

[0060] Coating durability test: The modification from step 2 was applied to the surface of ordinary flat glass. The sample was irradiated with a fluorescent ultraviolet lamp (UV-A340) for 15 days, and the coating was observed to see if it turned yellow. The results are shown in Table 3.

[0061] Table 3 Coating durability test results

[0062]

[0063] A comparison of the experimental data in Table 3 shows that the coating of the antique bricks prepared by this invention has aging resistance.

[0064] A comparison of the experimental data from Examples 1, 2, and 3 and Comparative Example 3 in Table 3 reveals that Examples 1, 2, and 3 did not turn yellow. The difference between Comparative Example 3 and the Examples is that flavonoids were not introduced through the reaction of amino groups with alkenes. This indicates that flavonoids possess strong antioxidant properties, capable of preventing the generation of free radicals and reducing their activity, thereby counteracting the oxidative damage caused by free radicals to the organic coating on the surface of antique bricks and extending the coating's service life.

[0065] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of the present invention. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
