Problems solved by technology

[0004] In addition, paints are often prone to bacteria and molds, causing mold spots on the surface of the coating to affect the aesthetic effect. It is necessary for the paint to have antibacterial and antiseptic effects, but the addition of antibacterial agents will further reduce the wear resistance of the paint.

Abstract

The invention provides a photocuring abrasion-resistant coating having an antibacterial performance. The photocuring abrasion-resistant coating comprises, by mass parts, 50-60 parts of oligomer, 5-6 parts of crosslinking agent, 10-15 parts of reactive diluent, 6-8 parts of photoinitiator, 0.8-1.5 parts of antifoaming agent, 1-1.5 parts of flatting agent, 1-1.2 parts of matting agent, 0.5-1 part of slip agent, 0.8-1.2 parts of wetting agent, 10-15 parts of solvent, 0.5-1 part of cellulose, 3-5 parts of abrasion-resistant additive, 3-5 parts of antibacterial agent and 0.8-1 part of preservative, wherein the oligomer is mixed solution of polysilicone emulsion and epoxy acrylate.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a light-cured wear-resistant coating with antibacterial properties and a preparation method thereof. Background technique [0002] Photocuring coating is a new type of coating that can undergo physical and chemical changes in a short period of time after being irradiated by ultraviolet light. Compared with traditional natural drying or heat-cured coatings, light-cured coatings not only have the advantages of fast curing speed, excellent performance, and wide application range of substrates, but also do not require external heat during the curing process, which is energy-saving and environmentally friendly. Cured coatings are used more and more widely. [0003] There are still some different problems in the current light-cured coatings. The existing light-cured coatings will produce shrinkage stress after being light-cured, resulting in brittleness, poor impact resistance and wear resista...
