Abstract

The invention relates to a durable antibacterial acrylic water-based coating. The durable antibacterial acrylic water-based coating contains durable antibacterial water-based acrylic resin, a filling,a coloring agent, an aid and deionized water, wherein the durable antibacterial water-based acrylic resin is prepared through the reaction of acrylic soft monomers, acrylic hard monomers, Schiff baseacrylic monomers, acrylic acid, azodiisobutyronitrile, hydroxied acrylate monomers, an emulsifying agent and deionized water; and the Schiff base acrylic monomers are prepared through the reaction ofsalicylaldehyde, R-NH2 and acryloyl chloride. The prepared durable antibacterial acrylic water-based coating is integrated with the characteristics of water-based acrylic resin and a Schiff base structure and has good adhesive force and water tolerance, and the efficient and durable antibacterial property is achieved without adding an antibacterial agent.

Description

technical field [0001] The invention relates to a water-based antibacterial coating, in particular to a durable bacterial type acrylic water-based coating, which belongs to the technical field of water-based functional coatings. Background technique [0002] In recent years, as human beings pay more attention to their own health, we have increased our requirements for the cleanliness of the living environment. However, in modern life, bacteria and germs are easy to breed and exist in various environments, such as: mobile phones, Computers, cameras and other equipment, the bacteria on these equipment are transmitted to the human body through different channels, which poses a great threat to human health and safety. In latex paint, some additives may become a source of nutrition for microorganisms. When the paint is Microbial pollution, as long as the growth conditions such as temperature and humidity are suitable, microorganisms will multiply and make the paint moldy and dete...
