Abstract

The invention provides an anti-fogging polyurethane acrylate resin and a preparation method thereof. The preparation method comprises the following steps of: reacting polyisocyanate with hydroxyl-terminated acrylate, and then reacting with hydroxyl-terminated quaternary ammonium salt to obtain the anti-fogging polyurethane acrylate resin. The raw materials are cheap and easy to obtain, and the manufacturing process is simple. The polyurethane acrylate resin has the characteristics of good anti-fog performance and rapid photocuring.

Description

technical field [0001] The invention belongs to the technical field of polymer material synthesis, and in particular relates to an anti-fogging polyurethane acrylate resin and a preparation method thereof. Background technique [0002] Fogging occurs frequently on optical materials used in everyday life such as bathroom mirrors, eyeglasses, goggles, swimming goggles, windshields, camera lenses, skis, and analytical and medical instruments. To overcome this dilemma, various materials and processes have been proposed for durable anti-fog coatings. Maechler et al. disclose the preparation of multilayer transparent anti-fog coatings based on polycarbonate. Cebeci et al. disclosed that a stable superhydrophilic nanofilm was prepared by layer-by-layer assembly of silica nanoparticles and polycations. Yuan et al. disclosed the preparation of an anti-fog coating of UV-curable hydrophilic acrylate polymer, which contains a certain amount of sulfonic acid groups and has good anti-fo...
