[0002] In recent years, ceramic manufacturers have developed a variety of functional tiles to meet the needs of user segments. In humid environments such as bathrooms and kitchens, bacteria easily breed on the surface of tiles to form biofilms, posing a risk of slipping. To address this problem, the industry has developed products such as negative oxygen ion antibacterial bricks and antibacterial glaze bricks, which achieve microbial inhibition by adding antibacterial agents such as silver ions and photocatalysts.

[0003] Although ceramic tile products with both antibacterial and anti-slip functions have appeared in the prior art, it has been found that there are still technical bottlenecks in actual applications. For example, there is a positive correlation between the durability of its anti-slip performance and the attenuation of its antibacterial efficacy. With the slow release of antibacterial ingredients, the surface friction coefficient shows a downward trend, and its anti-slip durability and long-term antibacterial performance cannot meet the use requirements.

[0004] In view of this, the purpose of the present invention is to provide a new technical solution to solve the existing technical problems. Summary of the invention

[0024] Ceramic tiles are widely used in high-humidity scenes such as bathrooms, kitchens, and balconies due to their decorative and functional properties. However, traditional ceramic tiles have two core defects in long-term humid environments: they are easy to breed bacteria and have a slippery surface, which leads to health and safety hazards and the risk of slipping. Although a variety of functional ceramic tiles have appeared on the market to address the above problems, the existing technology generally cannot effectively achieve long-term antibacterial and anti-slip properties. In order to achieve long-term anti-slip and antibacterial properties of ceramic tiles, the present application provides a method for preparing anti-slip and antibacterial ceramic tiles, comprising the following steps: S1. Preparation of ionic antibacterial agent: The inorganic antibacterial agent and the organic antibacterial agent were mixed in a molar ratio of (15-30): 1, glycerol was added, and the reaction was carried out at 150-200 ° C for 24 hours, and the ionic antibacterial agent was obtained by centrifugation, washing and drying; Among them, the inorganic antibacterial agent is one or more of zinc oxide, silver oxide or copper oxide; the organic antibacterial agent is one or more of dodecyltrimethylammonium bromide, hexadecyltrimethylammonium bromide, heptadecyltrimethylammonium bromide or nonadecyltrimethylammonium bromide.

[0025] In some specific embodiments, the inorganic antibacterial agent is nano zinc oxide.

[0026] In some specific embodiments, the molar ratio of the inorganic antibacterial agent to the organic antibacterial agent is (18-22):1.

[0027] In a specific embodiment, the molar ratio of the inorganic antibacterial agent to the organic antibacterial agent is 20:1.

[0028] S2. Preparation of antibacterial anti-slip wax water: The thermoplastic material and the solvent are mixed in a mass ratio of 1: (9-16), the colorant and the ionic antibacterial agent prepared in S1 are added, and the suspension is stirred in a water bath to obtain an antibacterial anti-slip wax water; Wherein, the mass ratio of the ionic antibacterial agent to the thermoplastic material is 1:(20-30); The thermoplastic material is one of polylactic acid, PP (polypropylene), PE (polyethylene), and PVA (polyvinyl alcohol), and the solvent is water, chloroform, or tetrachloromethane according to the selected thermoplastic material. The solvent is used to dissolve the thermoplastic material. For example, when the thermoplastic material is a non-polar material such as polylactic acid or PP, the solvent is an organic solvent such as chloroform or tetrachloromethane; when the thermoplastic material is a polar material such as polylactic acid, water is used as the solvent.

[0029] In some specific embodiments, the mass ratio of the ionic antibacterial agent to the thermoplastic material is 1:(25-29).

[0030] In a specific embodiment, the mass ratio of the ionic antibacterial agent to the thermoplastic material is 1:29.

[0031] In the antibacterial and anti-slip wax water, the thermoplastic material is dissolved in a solvent (such as chloroform). During the water bath heating process, the solvent will evaporate, the thermoplastic material will precipitate, and grow with the colorant as the crystal nucleus. With high-speed stirring, the thermoplastic material is dispersed to avoid agglomeration. In this process, the ionic zinc oxide wraps the thermoplastic material to form a suspension.

[0032] S3. Surface treatment: The antibacterial and anti-skid wax water prepared in S2 is applied to the surface of the tile body, and then baked and cured to form an anti-skid and antibacterial tile with a raised structure on the surface.

[0033] The baking temperature is above the boiling point of the solvent and below the melting point of the thermoplastic. For example, when the thermoplastic material is PP and the solvent is chloroform, the baking temperature is set to 100° C. After the antibacterial and anti-slip wax water is applied to the surface of the tile body, baking can soften the thermoplastic material and adhere to the surface of the tile body.

[0034] In some specific embodiments, the antibacterial and anti-slip wax coating has a thickness of 30-100 μm.

[0035] The antibacterial principle of the present invention is: Inorganic antimicrobial agents (such as zinc oxide) undergo high temperature and high pressure reactions with polyhydroxy organic matter to generate polyhydroxy structures (such as ZnO-OH) on their surfaces. Polyhydroxy zinc oxide and quaternary ammonium salt groups of organic antimicrobial agents (such as dodecyltrimethylammonium bromide) chemically combine to form R-(NH4⁺)-O-(ZnO)-O-, generating a positive and negative potential difference. By controlling the ratio of inorganic antimicrobial agents to organic antimicrobial agents, polyhydroxy zinc oxide reacts locally, and a potential difference is formed between the reacting local area and the unreacted area. The surface of bacterial cell membranes is usually negatively charged, and the positively charged area of ​​the composite antimicrobial agent destroys the bacterial membrane structure through electrostatic adsorption and contact sterilization, thereby enhancing the sterilization efficiency.

[0036] The anti-slip principle of the present application is as follows: zinc oxide will be adsorbed on the surface of the thermoplastic material during the preparation process, wrapping the thermoplastic material, and after baking, the thermoplastic material will form a raised structure on the surface of the tile body to achieve an anti-slip effect. Thermoplastic materials maintain rigidity at room temperature, and after baking and softening, they can be tightly combined with the tile body to form a wear-resistant coating. Thermoplastic materials have excellent durability, stable performance and wear resistance in long-term use; they are also resistant to water and chemical corrosion, and can be used in humid, acidic and alkaline environments, effectively avoiding the problems of aging and peeling of traditional rubber coatings.

[0037] Using glycerol as the main solvent to dissolve inorganic antimicrobial agents (such as zinc oxide) and organic antimicrobial agents (such as dodecyltrimethylammonium bromide) can ensure that the two are fully contacted and evenly mixed during high-temperature reactions. The high boiling point (about 290°C) of glycerol keeps it in liquid form under reaction conditions of 150-200°C, avoiding volatilization and causing system instability. In addition, during high-temperature and high-pressure reactions, the polar hydroxyl groups (-OH) of glycerol may bind to the surface of zinc oxide through hydrogen bonding, promoting the formation of polyhydroxy zinc oxide complexes. This composite structure helps to enhance the charge distribution of ionic antimicrobial agents (such as local positive / negative potential differences), thereby improving the bactericidal effect. In addition, the high viscosity of glycerol can prevent unreacted particles from agglomerating during centrifugation and washing, ensuring the purity and dispersibility of the ionic antimicrobial solids.

[0038] In a specific implementation, the ceramic tile blank is a white ceramic tile, and the colorant is titanium dioxide. In other embodiments, the ceramic tile blank can be made of ceramic tiles of other colors, such as red, black, blue, etc., and correspondingly, the inorganic colorant is iron red, iron black, phthalocyanine blue, etc. as the crystal nucleus, which is not limited here. It should be noted that the use of a colorant close to the color of the ceramic tile blank brick surface can not affect the beauty of the ceramic tile, and reduce the possibility of the protruding structure distributed on the brick surface to appear as color spots and affect the appearance.

[0039] like Figure 1-2 As shown, the present invention also provides: A non-slip antibacterial tile, referring to Figure 1 , prepared by the method described above.

[0040] Furthermore, the anti-slip and antibacterial ceramic tiles provided by the present invention have a static friction coefficient of ≥0.65, and a long-term antibacterial rate of >91%.

[0041] Reference Figure 2 In a specific embodiment, the surface roughness of the anti-slip antibacterial tile prepared by the above method is Sa=30.9. The anti-slip antibacterial tile has a high surface roughness, and its application in a humid environment (such as a bathroom, kitchen) can effectively reduce the risk of slipping.

[0054] Comparative Example 1: Antimicrobial glazed tiles available.

[0055] Comparative Example 2: Antibacterial wax water bricks are available.

[0056] Each embodiment and comparative example was tested respectively, and the test results were analyzed.

[0057] The following details the test steps and methods for each test item: National standard antibacterial rate test: Referring to the test standard of JC / T 897-2014, the detection method is the static immersion method, such as statically immersing the tiles for 24 hours, which is mainly used to evaluate the initial antibacterial properties of the tiles.

[0058] Testing standard: The antibacterial rate of ceramic products against designated bacteria (such as Escherichia coli and Staphylococcus aureus) should be ≥ 90% The antibacterial rate calculation formula is as follows:

[0059] Long-term antibacterial rate detection: Detection method: Escherichia coli spiked solution immersion test.

[0060] Long-term antibacterial rate testing steps: 1. Sample pretreatment: Rinse the surface of 200mm×200mm ceramic tiles with ultrapure water for 5 hours to remove the residual antimicrobial agent on the surface; then soak for 3 hours and rinse again for 1 hour to ensure that there is no free antimicrobial agent on the tile surface to interfere with the test.

[0061] 2. Bacterial inoculation: Use pure water to prepare a standard solution of E. coli with a concentration of 100,000±5,000 cfu / L; completely immerse the pretreated tiles in the bacterial solution and let it soak for 24 hours.

[0062] 3. Rinsing and sampling: Take out the tiles, rinse the surface with 1L of pure water, and collect all the rinse fluid; test the bacterial concentration of the rinse fluid and record the final colony count.

[0063] Testing standard: After long-term use or simulated environment testing, the antibacterial performance retention rate should be ≥85%.

[0064] Among them, the calculation formula for long-term antibacterial rate is as follows:

[0065] Static friction coefficient test: Testing method: Test in accordance with GB / T 4100 standard.

[0066] Testing standards: ordinary areas ≥ 0.50; high humidity areas ≥ 0.70.

[0067] Based on the above test contents, the relevant results are summarized in Table 1: Table 1

[0068] It can be seen from Table 1 that the national standard antibacterial rates of the anti-slip antibacterial tiles prepared in Examples 1-12 all reached 99.99%, indicating that the anti-slip antibacterial tiles prepared have strong initial antibacterial properties; the long-term antibacterial properties of Examples 1-12 also reached more than 91%, and their long-term antibacterial rates were much greater than the long-term antibacterial standards, indicating that the anti-slip antibacterial tiles have strong antibacterial durability; the static friction coefficients of Examples 1-12 are all ≥0.65, which indicates that the anti-slip antibacterial tiles prepared by the present invention meet the anti-slip requirements of ordinary areas, and the static friction coefficients of multiple raw material ratios (such as Examples 1-9) are ≥0.71, which indicates that the tiles prepared under these raw material ratios have better anti-slip properties and can be used in high-humidity areas. The antibacterial glazed tiles in Comparative Example 1 are weaker than the anti-slip antibacterial tiles of the present invention in terms of initial antibacterial effect, and their long-term antibacterial effect and anti-slip effect are also inferior to the anti-slip antibacterial tiles of the present invention; the antibacterial wax water bricks in Comparative Example 2 have almost no long-term antibacterial performance, and their anti-slip performance is also inferior to the anti-slip antibacterial tiles of the present invention.

[0069] In summary, compared with the existing antibacterial glazed tiles or antibacterial wax water tiles, the anti-slip antibacterial tiles prepared by the present invention can take into account the initial antibacterial performance, long-term antibacterial and anti-slip performance, and have long-term stability in anti-slip and antibacterial properties.

[0070] 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.
