Problems solved by technology

The hardness of the coating is greater than 2H, and the wear resistance is good, but the continuous anti-fog performance is average. The curing process takes a long time, and it needs to be cured in sections (50 ° C ~ 120 ° C), and the process is relatively complicated.
[0007] In order to overcome the contradiction between the continuous anti-fog performance and wear resistance of traditional anti-fog coatings on the market, the present invention discloses a UV photocurable hydrophilic anti-fog coating

Abstract

The invention provides a UV photo-cured anti-fog paint composition. The composition is prepared from, by weight, 35-80 parts of hydrophilic photo-cured resin, 15-50 parts of hydrophobic photo-cured resin, 5-15 parts of hydrophilic photo-cured monomers, 1-5 parts of photoinitiator and 0.01-0.05 part of auxiliaries. The composition further comprises a solvent. The weight of the solvent is 2-4 times of the total weight of the other components. After UV anti-fog paint is photo-cured by UV, the water resistance of a paint film is improved, durable anti-fog performance is achieved, the hardness of the paint film is high, and scrubbing resistance is good.

Description

technical field [0001] The invention belongs to the field of light-curing coatings, in particular to a UV light-curing anti-fog coating composition. Background technique [0002] When the water vapor in the air is lower than the dew point, it will condense into tiny liquid droplets to form fog. This adverse effect often occurs on windows, bathroom mirrors, glasses, swimming and diving glasses, windshields, optical instrument lenses, car lights, indicator lights, agricultural films and other transparent materials that are closely related to our lives. As a result of the atomization of water droplets on the surface of transparent materials, not only the decrease of light transmittance will affect the vision, but sometimes it will cause harm. For example, when the droplets condense on the lens surface of precision analysis instruments such as infrared optical microscopes, the accuracy of its analysis will be reduced. When the fog droplets condense on the solar cell light-trans...
