Abstract

The invention discloses application of a UV curing coat in an anti-dazzling thin membrane for an automobile rear view mirror or side view mirror. The water contacting angle of the UV curing coat is smaller than 20 degrees. According to the application, the UV curing coat with a specific water contacting angle is applied to the mirror surface of the automobile rear view mirror or side mirror, an excellent anti-fogging effect is achieved, the UV curing coat comes into effect in a raining or dampness environment to prevent membrane surface from dimming and fogging, and therefore the driving safety can be improved.

Description

technical field [0001] The invention relates to a new application of UV curable coatings, in particular to the application of UV curable coatings in anti-glare films for automobile rearview mirrors or side view mirrors. Background technique [0002] UV-curable coatings have the advantages of fast curing speed, room temperature curing, and environmental protection. The film layer has high brightness and the film surface is firm and heat-resistant after drying. It has been widely used in household, chemical, electronic light industry and other fields. [0003] According to market needs and application fields, the research direction of UV curable coatings mainly focuses on improving wear resistance, scratch resistance, and weather resistance. Such as CN106147586A discloses a kind of ultraviolet curing water-based UV coating, which comprises polyurethane acrylate, modified polyurethane acrylic acid, reactive diluent, photoinitiator, mixed solvent, cosolvent, auxiliary agent, sur...
