Embodiment 1-4

[0025] Components of Table 1 Embodiment 1-4 and parts by weight thereof

[0026]

[0027] The ZXL-CFW (product code) used in Examples 1-4 is an aqueous dispersion formed by dispersing hydroxyl-modified nano-silica in water. The ZXL-CQS (product code) used in Examples 1-4 is an aqueous dispersion formed by dispersing amino-modified nano-titanium dioxide in water. The solid content of the super-hydrophilic nano-silica water dispersion and the super-hydrophilic nano-titanium dioxide water dispersion are both 10%-12%.

[0028] The preparation process of the anti-fog film: weigh the water-based UV-curable resin, water-based heat-curable resin, super-hydrophilic nano-silica aqueous dispersion, super-hydrophilic nano-titanium dioxide aqueous dispersion according to the components in Table 1 and their parts by weight. Liquid, water-based additives, water-based leveling agent, cross-linking agent and photoinitiator are added to a stirrer and stirred at high speed for 30-50 minutes,...

Abstract

The invention relates to an anti-fog coating, an anti-fog film and a preparation method of the anti-fog coating. The anti-fog coating comprises the following components in parts by weight: 20-80 partsof water-based ultraviolet curing resin, 10-40 parts of water-based thermosetting resin, 10-30 parts of super-hydrophilic nano-silica water dispersion, 20-60 parts of super-hydrophilic nano-titania water dispersion, 20-60 parts of a water-based auxiliary agent, 0.1-1 part of a water-based flatting agent, 1-4 parts of a cross-linking agent and 3-8 parts of a photoinitiator. The anti-fog film comprises a transparent base material layer and an anti-fog coating attached to the surface of the transparent base material layer. And the anti-fog coating is prepared by coating the anti-fog coating andcarrying out dual curing of thermal curing and ultraviolet curing. The anti-fog film prepared by the invention has very excellent hardness, wear resistance and anti-fog performance, also has antibacterial performance, and has very wide application prospect.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to an anti-fog coating, an anti-fog film and a preparation method thereof. Background technique [0002] In rainy or cold weather, the surfaces of car rearview mirrors and helmets worn by non-motor vehicle drivers will be wet or fogged to form water drops, which will hinder the driver's vision and seriously affect the driver's awareness of road driving conditions. Judgment can easily lead to the occurrence of traffic safety accidents. Therefore, it is necessary to add an anti-fog film on the surface of these materials that are easily wetted or fogged to avoid the formation of water droplets. At present, most of the anti-fog films on the market cannot have good wear resistance and continuous anti-fog performance at the same time. Disclosed in CN105315735A is a hydrophilic anti-fog coating composition with dual curing of light and heat. Through the dual curing method of th...
