Abstract

The invention provides an anti-fog and anti-frost film and a preparation method thereof. The anti-fog and anti-frost film comprises a bottom UV curing anti-fog layer and a top water-based anti-fog and anti-frost layer. The bottom UV curing anti-fog layer is prepared from, by weight, 10-30 parts of UV resin oligomer, 10-30 parts of an acrylic monomer, 20-100 parts of a surfactant containing an acrylic acid group, and 3-10 parts of a photoinitiator. The top water-based anti-fog and anti-frost layer is prepared from the following raw materials in parts by weight: 70-90 parts of water-based polyurethane, 5-30 parts of a surfactant, and 5-10 parts of a material capable of reducing the freezing point of water. The anti-fog and anti-frost film provided by the invention has a double-layer structure, and has a relatively good anti-fog effect and a relatively good anti-frost effect.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and relates to an anti-fog and anti-frost film and a preparation method thereof. Background technique [0002] When the surface of a transparent material (such as a glass surface) is humid and the temperature is uneven inside and outside, it is easy to produce a layer of fog or frost formed by water, which will cause the transparency or reflectivity of the transparent material to deteriorate. For example, the windshield of a car is covered with a layer of fog in winter, which will cause a lot of trouble to the driver. It is necessary to constantly wipe the glass while driving, which has caused great potential harm to traffic. In addition, the glass surfaces of aviation aircraft, instruments and meters in workshops, glasses, etc. are also prone to fogging, which brings great inconvenience to people. [0003] At present, anti-fog coatings (or anti-fog films) generally use hydrophilic or ...
