Abstract

The invention discloses a high-hydrophilicity high-wear-resistance organic / inorganic hybrid photocuring paint composition. The composition comprises 60-75 parts of hydrophilic photocuring low polymer, 5-15 parts of high-functionality photocuring resin, 12-20 parts of reactive diluent, 4-6 parts of photoinitiator, 0.01-0.5 part of assistant and 0.4-2 parts of inorganic functional additive. The inorganic functional additive is selected from polyvinyl silsesquioxane, methylacryloyloxy silsesquioxane and acryloyloxy silsesquioxane. The ultraviolet-curing hydrophilic paint disclosed by the invention can be applied to a glass surface; and the cured paint has the advantages of excellent hydrophilicity, excellent physical properties, favorable adhesive force, favorable water resistance, favorable acid resistance and favorable wear resistance.

Description

technical field [0001] The invention belongs to the field of ultraviolet curing coatings, in particular to a highly hydrophilic and highly wear-resistant organic / inorganic hybrid photocuring coating composition. Background technique [0002] With the improvement of people's living standards, people have higher requirements for the performance of some traditional materials, among which there are higher requirements for the transparency of some transparent materials, such as glass, in high humidity or water environment . Among them, it is widely used in automobile glass and bathroom glass / mirror. On the car glass, the front and rear windshields can have wipers to ensure that it will not affect the line of sight in rainy days, but the rearview mirror and the side window glass of the car do not have this function, so that the surfaces of these two parts will be blurred in rainy days. A large number of water droplets adhere to the surface, which affects the driver's observation...
