Description

Technical Field

[0001] The invention belongs to the field of sanitary materials, and in particular relates to a UV light-cured hydrophobic antibacterial material and a preparation method thereof. Technical Background

[0002] As people pursue a better quality of life, bathroom products are constantly being upgraded, and health and intelligence have become the direction of product development. What needs attention is that there are many sources of microbial contamination in the bathroom space. Bathtubs / tubs and showers have water flowing all year round, and the warm and humid environment provides a breeding ground for bacteria. If the cleaning work is not in place, it is easy to breed a large number of bacteria. Therefore, the antibacterial issue has become an important concern for bathroom products. It is of great significance to prepare materials with high efficiency, broad spectrum, health, safety, long-term effect and high stability for bathroom products.

[0003] Bathroom products are products that consumers use every day, but due to the humid environment, bathroom products are prone to bacteria, which is not good for human health. Although there are some bathroom materials that claim to have bactericidal functions, their antibacterial effects are poor and do not last long. At the same time, the preparation cost is high, which is not conducive to promotion and use.

[0004] Patent document CN106673633A discloses an antibacterial sanitary ceramic product and a preparation method thereof, including a body and a glaze, wherein the raw materials of the glaze contain titanium dioxide and nano-silver that can kill bacteria. The raw materials of the body are crushed, wet ball milled, left to age, slip cast, demolded, dried, and bisque fired to obtain a body; then the glaze is wet ball milled, left to age, and then sprayed on the surface of the body to obtain a product to be fired, and then glaze fired to obtain an antibacterial sanitary ceramic product. The antibacterial sanitary ceramic product prepared by the invention has good weather resistance, antibacterial properties, and low water absorption, but the method is only applicable to the preparation of ceramic materials. Patent CN116446013 invented a method for preparing a wear-resistant antibacterial coating for bathroom hardware. By preparing a composite material of metal organic framework material coated with metal particles, an electrochemical deposition reaction is used to form a wear-resistant antibacterial coating on the surface of the bathroom hardware substrate. The coating prepared by the invention not only has excellent antibacterial and self-cleaning properties, but also has a strong bond with the substrate, which can meet the long-term use requirements of bathroom hardware under harsh conditions. However, the only drawback is that this method uses electrochemical deposition reaction, which is only useful for metal substrates and will not be suitable for some non-conductive bathroom products. However, its method for preparing antibacterial coatings on the surface of materials provides a reference idea. Summary of the invention
