Abstract

The invention provides a super stain resistance ultraviolet curing coating. The super stain resistance ultraviolet curing coating comprises 15-40 parts of organic silicon modified urethane acrylate resin, 5-15 parts of fluorine-containing acrylate monomer, 0.5-5 parts of perfluorooctyl triethoxysilane, 5-15 parts of nanometer titania, 30-60 parts of thinner and 1-6 parts of photoinitiator in parts by weight. According to an ultraviolet light curing super-hydrophobic wear-resistant coating provided by the invention, an optimum super-hydrophobic effect of the coating is synergistically developed by coordinating the using amounts of organic silicon modified urethane acrylate resin, fluorine-containing acrylate monomer and nanometer titania.

Description

technical field [0001] The invention relates to the field of ultraviolet light coatings, in particular to a super antifouling ultraviolet light curing coating. Background technique [0002] The surface of the lotus leaf has a rough microscopic topography and a hydrophobic cuticle wax. This special structure helps to lock the air, thereby preventing water from wetting the surface of the lotus leaf. Water droplets form a sphere on the lotus leaf instead of spreading out. A surface like this is a "superhydrophobic surface". This super-hydrophobic surface can effectively prevent contamination by sewage, and the dust and impurities on the surface will also be taken away by rainwater, so it can play a self-cleaning "lotus leaf effect". In recent years, artificial superhydrophobic surfaces imitating lotus leaves have emerged. However, many existing superhydrophobic surfaces are easily contaminated by oil and lose their superhydrophobicity. On the other hand, most of the existing...
