Abstract

The invention provides an antifogging hydrophilic film and a preparation method and application thereof, the antifogging hydrophilic film is prepared from the following raw materials: resin master batch and an additive, and the additive comprises water-absorbing ionic liquid, an ionic liquid type surfactant and a nonionic surfactant. The water-absorbing ionic liquid disclosed by the invention can be well adsorbed in a resin structure, so that the water absorbing capacity of the anti-fog hydrophilic film is greatly improved; the ionic liquid type surfactant disclosed by the invention not only has relatively good compatibility with the water-absorbing ionic liquid, but also has relatively good compatibility with the nonionic surfactant, so that hydrophilic and surface active effects are achieved in a resin system, and meanwhile, seepage of the nonionic surfactant is also reduced.

Description

technical field [0001] The invention belongs to the technical field of coatings, and relates to an anti-fog hydrophilic film and its preparation method and application, in particular to an anti-fog hydrophilic film added with ionic liquid, its preparation method and application. Background technique [0002] Transparent substrates, such as glass, plastic, etc., when there is a difference in temperature and humidity between the inner surface and the outer surface, causing one surface to be below the dew point, or when external environmental factors cause a large change in the temperature and humidity of the substrate surface, such as When boiling water vapor contacts the substrate and moves from a low-temperature environment to a high-temperature and humid environment, the moisture in the air tends to adhere to the surface of the substrate in the form of water droplets, thereby condensing into dew on the surface of the substrate, and the condensed water droplets cause light sc...
