Problems solved by technology

[0003] In daily life, the human face is easy to secrete sweat and oil, and sweat and oil are easy to drip or adhere to the lens of the glasses. Ordinary glasses lenses have poor hydrophobic and oil-repellent effects, which makes it inconvenient to clean the glasses lenses, affecting wearing comfort and clear vision The anti-ultraviolet performance of ordinary spectacle lens film is average, and ultraviolet rays can easily cause damage to the eyeball, which is not conducive to protecting the eyeball

Abstract

The invention discloses an oil stain-resistant thin film. The oil stain-resistant thin film is prepared from the following raw materials in parts by weight: 60 to 80 parts of bisphenol A type epoxy resin, 20 to 30 parts of polyacrylate, 5 to 10 parts of o-cresol formaldehyde epoxy resin, 5 to 10 parts of polyethylene terephthalate, 3 to 5 parts of zinc oxide, 2 to 4 parts of polyaluminum iron silicate, 1 to 2 parts of 2-hydroxyl-4-methoxybenzophenone, 1 to 2 parts of 2-(2'-hydroxyl-5'-tert octyl phenyl)benzotriazole, 6 to 10 parts of organic solvent, 2 to 4 parts of flatting agent, 1 to 3 parts of curing agent, 0.5 to 1.5 parts of photoinitiator and 0.5 to 1 part of antioxidant. The invention also discloses a preparation method of the oil stain-resistant thin film. Under the common matching action of all raw materials, the oil stain-resistant thin film prepared by the invention is strong in anti-ultraviolet capacity, and the damage of ultraviolet rays to eyes can be reduced.

Description

technical field [0001] The invention relates to the technical field of thin films, in particular to an oil stain-resistant thin film and a preparation method thereof. Background technique [0002] Glasses are lens lenses embedded in the frame and worn in front of the eyes to improve vision, protect eyes or for decoration. Glasses can correct a variety of vision problems, including myopia, hyperopia, astigmatism, presbyopia or strabismus, etc. Existing spectacle lenses are mostly made of resin, with strong hardness and light weight. In order to improve the performance of spectacle lenses, often The surface of the lens is coated. [0003] In daily life, the human face is easy to secrete sweat and oil, and sweat and oil are easy to drip or adhere to the lens of the glasses. Ordinary glasses lenses have poor hydrophobic and oil-repellent effects, which makes it inconvenient to clean the glasses lenses, affecting wearing comfort and clear vision The anti-ultraviolet performance...
