Antibacterial lining aluminum plate applied to household appliances and preparation method of antibacterial lining aluminum plate

Abstract

The invention provides an antibacterial lining aluminum plate applied to household appliances. The antibacterial lining aluminum plate comprises an aluminum plate body and an antibacterial coating covering the surface of the aluminum plate body. The antibacterial coating is prepared from the following components in parts by weight: 45-65 parts of N-[4-(sulfonamide) phenyl] acrylamide/brominated 3-allyl benzothiazole/N-trihydroxymethyl methacrylamide/glycidyl methacrylate copolymer, 5-10 parts of 2, 2-bis [4-(4-aminophenoxy) phenyl]-1, 1, 1, 3, 3, 4-tetramethyl-1, 3-pentanediol monoisobutyrate, 5-10 parts of a silane coupling agent, 1-5 parts of a coupling agent, 1-5 parts of a coupling agent, 1-5 parts of a coupling agent, 1-5 parts of a coupling agent and 1-5 parts of a coupling agent. The coating is prepared from the following components in parts by weight: 4 to 6 parts of 1, 1, 1, 3, 3-hexafluoropropane, 0.8 to 1.2 parts of aluminum dihydroxyamino acetate, 10 to 15 parts of filler, 1 to 2 parts of dispersing agent, 0.5 to 1.5 parts of defoaming agent, 0.3 to 0.8 part of flatting agent and 40 to 50 parts of solvent. The invention further discloses a manufacturing method of the antibacterial lining aluminum plate applied to the household appliances. The antibacterial lining aluminum plate applied to the household appliances is remarkable in antibacterial effect, good in antibacterial durability and long in service life.

Description

technical field [0001] The invention relates to the technical field of materials for household appliances, in particular to an antibacterial lining aluminum plate applied to household appliances and a preparation method thereof. Background technique [0002] With the rapid development of the home appliance industry, especially white goods, the development of home appliance lining coating boards with antibacterial and other functions, which are used in the lining of food-contact home appliances such as freezers, medicine cabinets, wine cabinets, and display cabinets, is a manifestation of a home appliance. It is an important symbol of the manufacturer and its suppliers on the level of process quality, management level and product innovation ability. A refrigerator is a common household appliance, which is usually used to preserve items such as food at a low temperature. Existing refrigerator linings are usually made of aluminum plates. However, aluminum plates are usually no...

AI Technical Summary

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
