Problems solved by technology

Most of the common antibacterial coatings on the market are based on the addition of fungicides. The disadvantages are toxicity, unsafe, easy to dissolve, and poor durability.
Common antibacterial coatings used for electronic products have the following two types: 1) Solvent-based light-curing coatings. The disadvantage is that after curing into a film, the antibacterial ability is destroyed, and there is no antibacterial or antibacterial ability.
2) Although water-based products also have a certain antibacterial and antibacterial ability, after forming a film, the antibacterial and antibacterial ability will decrease rapidly or completely lose the antibacterial ability, and the antibacterial ability is very limited

Abstract

The invention discloses an antimicrobial ultraviolet-curing paint and a preparation method thereof. The paint is prepared by mixing polyurethane acrylate, active acrylate monomer, initiator, leveling agent, special antimicrobial agent and diluter. The preparation method comprises the steps of proportioning, dispersing and conditioning. According to the antimicrobial ultraviolet-curing paint, the high-activity high-reaction-speed polyurethane acrylate is used as the main component and carrier, the special antimicrobial agent and ultraviolet initiator are used as curing agents, the leveling agent is used as an auxiliary material, and the active acrylate monomer and diluter are used as viscosity modifiers, so that the ultraviolet-curing paint has antibacterial action.

Description

technical field [0001] The invention relates to the field of coatings, in particular to an ultraviolet light curing UV coating and a preparation method thereof. Background technique [0002] With the advancement of science and technology and the improvement of people's living standards, people use more and more electronic products such as mobile phones in their daily life. In recent years, there have been relevant data pointing out that when daily electronic products are in contact with people for a long time, bacteria will continue to grow and multiply on electronic products, and eventually infect the human body through frequent contact with people, endangering human health. Therefore, the coating technology with antibacterial function came into being. Most of the common antibacterial coatings on the market are based on the addition of fungicides. The disadvantages are toxicity, unsafe, easy to dissolve, and poor durability. Common antibacterial coatings used for electron...
