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 hydrophilic anti-fog coating with dual curing of light and heat

Abstract

The invention discloses a photo-thermally cured hydrophilic anti-fog paint composition which comprises the following ingredients: 32-50 parts of hydrophilic thermal-curing resin, 10-15 parts of a waterborne curing agent, 10-20 parts of hydroxy acrylate monomer, 10-20 parts of a polymerizable surfactant, 0.5-1 part of a photoinitiator, 5-10 parts of a cosolvent and 400 parts of water. The photo-thermally cured hydrophilic anti-fog paint composition provided by the invention can be applied to the surface of a plastic base material, is firstly thermally cured and then photo-cured, has good constant fogging resistance and abrasion resistance, meanwhile, has good adhesive force to the plastic base material, can be widely applied to anti-fog vehicle window film, anti-fog vehicle headlights, bathroom mirrors and the like and has a good application prospect.

Description

technical field [0001] The invention belongs to the field of photothermal dual curing coatings, in particular to a hydrophilic anti-fog coating composition with photothermal dual curing. Background technique [0002] In daily life, due to the obvious temperature difference and humidity difference on both sides of the glass. When the vaporized liquid in the air on the higher temperature side encounters the glass, it will condense on the glass surface to form small liquid droplets with poor fluidity, which will cause fog on the glass surface. Small droplets on the glass surface can cause irregular scattering, reflection and diffraction of light, which significantly affects the transmission ability of light. [0003] In order to solve these problems, the surface of the material is generally treated with hydrophobic or hydrophilic treatment. Hydrophobic resins are commonly used as perfluorinated resins. On the one hand, the price is high. On the other hand, this type of resin ...
