Abstract

The invention relates to the technical field of photocureable coating, in particular to solvent type spraying photocuring antibacterial coating as well as a preparation method and application thereof.The invention discloses the solvent type spraying photocuring antibacterial coating. The preparation raw materials of the antibacterial coating at least comprise the following components in percentage by weight: 15-25% of urethane acrylate, 10-20% of epoxy acrylate, 5-20% of light-cured antibacterial resin, 15-25% of an active monomer, 25-40% of a solvent, 1-5% of an initiator and 0.1-0.5% of anassistant. According to the coating, by adjusting the ratio of the raw materials, the compatibility and the synergistic effect between systems are improved, the spraying process requirements of the solvent type photocuring coating are met, consumer electronic products such as mobile phones, laptops and household appliances are coated with the solvent type photocuring coating in a spraying mode, surface decoration and protection are conducted, and the excellent and lasting antibacterial effect is achieved.

Description

technical field [0001] The invention relates to the technical field of light-curing coatings, in particular to a solvent-based spraying light-curing antibacterial coating and its preparation method and application. Background technique [0002] For a long time, pathogens such as bacteria and molds have caused great harm to the health of humans or animals, and can also cause decomposition and damage of materials and deterioration of food, resulting in great health and economic losses. Therefore, how to reduce or even avoid the harm of bacteria and other pathogens to the environment and human body has become a problem that people have always hoped to solve. application. Photocurable coatings have the characteristics of 5E, namely Efficient (high efficiency), Enabling (wide application), Economical (economical), Energy saying (energy saving), Environmental-friendly (environmental friendly). At present, UV-curable coatings have been widely used in fields closely related to lif...
