Abstract

The invention provides an UV curing coating, a wear-resistant and antifouling coating layer and a mobile phone protection film containing the wear-resistant and antifouling coating layer. The coating comprises, in parts by weight, 10-95 parts of a first prepolymer, 5-60 parts of a second prepolymer, 0.05-8 parts of a polysilazane-based polymer, 0.05-8 parts of a fluorine-containing aid, 1-15 parts of a photoinitiator and 100-300 parts of a solvent, wherein the first prepolymer is a urethane acrylate prepolymer with a functionality degree of 4-8; the second prepolymer is an acrylate prepolymer with a functionality degree of 9-18. The wear resistance of the coating layer formed after curing the UV curing coating can be improved by the first prepolymer and the second prepolymer with high functionality degrees, improvement for the wear resistance of the coating layer and prolonging for the service life of the coating layer are benefited due to the adding of the polysilazane-based polymer and a polar compound, and the good antifouling performance of the coating layer can be ensured, and the reduction of the antifouling performance of the coating layer can be suppressed due to the fluorine-containing aid. The coating layer has both good antifouling performance and wear resistance.

Description

technical field [0001] The invention relates to the technical field of protective films, in particular to a UV curable coating, a wear-resistant and anti-fouling coating and a mobile phone protective film containing the wear-resistant and anti-fouling coating. Background technique [0002] With the development of science and technology, people have higher and higher requirements for the appearance protection of various electronic devices. As a common product, mobile phone protective film needs to have certain scratch resistance, wear resistance, high transparency and stain resistance. Generally speaking, the protective film for mobile phones needs to be coated with a protective hard coating on the surface of the PET film, and at the same time, the coating does not affect the appearance and ornamental performance of the film. The steel wool #0000 resistance of conventional PET protective film hard coatings on the market is generally lower than 500 times / 1kg, and its water co...
