Problems solved by technology

However, during the use of transparent substrates, the surface of the substrate is caused by the infiltration of water vapor in a high-temperature and high-humidity environment, and fogging / white fog often occurs on the surface of the substrate, resulting in a decrease in the light transmittance of the substrate and affecting the line of sight. Inconvenience, even danger

Embodiment Construction

[0022] In order to prevent the surface of the substrate from fogging, there are generally two methods. The first method is to eliminate water vapor or temperature difference. Although it is difficult to eliminate water vapor in the air, the surface temperature of the substrate is always higher than the dew point of the water vapor by means of heating, such as power heating or infrared radiation. However, these The heating method is expensive and energy-intensive. The second method is to change the wettability of the substrate surface, such as making the substrate surface hydrophilic or hydrophobic. When the surface of the substrate is hydrophilic, the contact angle of the surface of the substrate to water can be reduced, so that the small water droplets condensed on the surface will not form tiny water droplets, but spread on the surface to form a film, reducing the diffusion of light, This ensures the transparency of the material. In addition, if a layer of hydrophobic subs...

Abstract

The invention provides an anti-fog coating composition, a prepared optical film and a display device with the optical film. The anti-fogging coating composition of the present invention includes two different first (meth)acrylic monomers and second (meth)acrylic monomers, and the viscosity at a temperature of 25° C. is less than 65 cps, respectively, and at a temperature of 20° C. The surface tensions are in the range of 36 dynes / cm to 42 dynes / cm respectively, wherein the two different (meth)acrylic monomers are in the same weight percentage and equal ratio (1:1) mixing; and a third (meth)acrylic monomer, whose viscosity at a temperature of 25°C is between 90cps and 500cps, and a surface tension at a temperature of 20°C of between 36 dynes / cm and 42 dynes / cm between. The anti-fog coating composition of the present invention can prepare an anti-fog, rub-resistant and explosion-proof optical film.

Description

technical field [0001] The present invention relates to a coating composition, a prepared film layer and a display device comprising the same, and in particular to an anti-fog coating composition, a prepared optical film and a display device having the optical film . Background technique [0002] Transparent substrates (such as glass, plastic, etc.) are indispensable materials in people's daily life, work and production. For example, attaching an optical film to the surface of a transparent substrate to provide the desired optical purpose, or attaching an optical film containing an adhesive layer to the surface of the transparent substrate, can have both optical functions and prevent the glass from splashing and hurting people after breaking. explosion-proof function. However, in the process of using the transparent substrate, due to the infiltration of water vapor in the high temperature and high humidity environment, the surface of the substrate often produces fog / white ...
