Problems solved by technology

The current commercialized superhydrophilic anti-fog coatings are mainly pure polymer material systems. The hydrophilic groups that play a superhydrophilic role in this material are connected to the main chain of the polymer, which makes the water resistance of this coating poor. , resulting in a short service life and poor weather resistance of the super-hydrophilic coating
At the same time, the hardness of the coating prepared by this coating is also low, and the wear resistance, scratch resistance, anti-fingerprint, and stain resistance are relatively poor.

Abstract

The invention relates to a superhydrophilic anti-fogging nano zirconiumhydrogen phosphate hybrid coating. The superhydrophilic anti-fogging nano zirconiumhydrogen phosphate hybrid coating comprises, by weight, 8 to 20 parts of zirconiumhydrogen phosphate containing olefinic bonds and sulfonic acid groups, 5 to 30 parts of a UV resin oligomer, 5 to 15 parts of a reactive diluent containing 1 to 6 functional groups, 0.5 to 2 parts of a levelling agent, 10 to 50 parts of a solvent, and 2 to 6 parts of a photoinitiator. A preparation method of the superhydrophilic anti-fogging nano zirconiumhydrogen phosphate hybrid coating comprises following steps: the zirconiumhydrogen phosphate containing olefinic bonds and sulfonic acid groups is subjected to ultrasonic dispersion in the solvent; the UV resin oligomer, the reactive diluent containing 1 to 6 functional groups, the leveling agent, and the photoinitiator are added; and ultrasonic dispersion is carried out for a second time after uniform stirring. The superhydrophilic anti-fogging nano zirconiumhydrogen phosphate hybrid coating possesses excellent superhydrophilic anti-fogging performance, water resistance, and weathering resistance, and long service life; and hardness, wear resistance, scratch resistance, finger print pollution resistance, and stain resistance of coating layers prepared from the superhydrophilic anti-fogging nano zirconiumhydrogen phosphate hybrid coating are excellent.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a superhydrophilic anti-fog nano zirconium hydrogen phosphate hybrid coating. Background technique [0002] The contact angle of water on the surface of transparent materials such as glass, plastic, and film is above 40°. When there is a temperature difference between the inner and outer surfaces, water vapor will condense on the surface of the material to form fog when it is cold, affecting the transparency of the material. Coating a transparent coating with super hydrophilic properties on the surface of the material can make the contact angle of water on the surface of the material below 5°, so that the water mist or water droplets on the surface of the material will spread on the surface of the material to form a water film. Does not affect the transparency of the material, thus achieving the purpose of anti-fog. The current commercialized superhydrophilic anti-fog coatings ...
