Abstract

The invention discloses an anti-fog urethane acrylate coating as well as a preparation method and a use method thereof. The invention relates to the technical field of urethane acrylate coatings. Thecoating comprises the following raw materials in parts by weight: 30-50 parts of urethane acrylate, 15-40 parts of acrylic resin, 10-15 parts of a carboxylated graphene dispersion liquid, 40-60 partsof a solvent, 1-5 parts of a photoinitiator and 0.1-1 part of a catalyst. According to the invention, hydrophilic pure acrylic resin is matched with hydrophobic urethane acrylate, and a hydrophilic and hydrophobic partially cross-linked network structure is formed after photocuring; meanwhile, the carboxylated graphene dispersion liquid has hydrophilicity, so that water drops are easy to spread onthe coating to form a water film without fogging; meanwhile, graphene is introduced, so that various film-forming properties of the prepared ultraviolet curing anti-fog coating are excellent, and hydrophilicity and adhesive force of carboxylated graphene can be reserved.

Description

technical field [0001] The invention relates to the technical field of polyurethane acrylate coatings, in particular to an anti-fog polyurethane acrylate coating and a preparation and application method thereof. Background technique [0002] In daily life, when the temperature of water vapor in the air is lower than the dew point, it will condense into tiny liquid droplets to form fog. When the vaporized liquid in the air on the higher temperature side encounters materials such as plastic or glass, it will condense on the surface to form small droplets with poor fluidity, which will cause fog on the surface of the plastic or glass. This phenomenon often occurs on windows, bathroom mirrors, glasses, swimming and diving glasses, windshields, optical instrument lenses, car lights, indicator lights, agricultural films and other transparent materials that are closely related to our lives. These small droplets can cause irregular scattering, reflection and diffraction of light, w...
