Problems solved by technology

However, the existing antibacterial lining aluminum sheets used in home appliances still have more or less defects such as low bond strength, insufficient weather resistance, limited antibacterial function, and short service life.
During long-term use, the antibacterial functional components will leak out, making the antibacterial durability of the material poor, and due to the selection of antibacterial functional components, the antibacterial function is single, only effective for some bacterial species, and its antibacterial broad spectrum is insufficient
[0004] In order to solve the above problems, Chinese invention patent application CN112521788A discloses a method for preparing an antibacterial coating for lining aluminum plates of refrigerators, which is made of the following raw materials: 50-55 parts of polyester resin, 2-3 parts of adhesive agent, hexamethylene 1-2 parts of tetramine, 4-8 parts of xylene, 3-6 parts of ethyl acetate, 2-4 parts of n-butanol, 0.1-0.2 parts of manganese naphthenate, 25-30 parts of titanium dioxide, 5- 10 parts, 2-4 parts of yellow powder, 0.2-0.3 parts of catalyst, 0.3-0.6 parts of dispersant, 0.2-0.3 parts of defoamer, 0.15-0.25 parts of leveling agent; by preparing antibacterial coatings, it can effectively solve the problem of the existing aluminum plate Without antibacterial treatment, a large number of bacteria will be produced during use, which will cause pollution to the items in the refrigerator
However, the coating's weather resistance, antibacterial properties and bonding strength need to be further improved
