Anti-fogging film and preparation method thereof

Abstract

The invention relates to an anti-fogging film and a preparation method thereof. The anti-fogging film comprises a PET (Polyethylene Terepthalate) base material, wherein an anti-fogging layer is arranged on the PET base material; the thickness of the anti-fogging layer is 5 to 20 microns; a protective film is arranged on the anti-fogging layer; the thickness of the protective film is 25 to 35 microns; the lower part of the PET base material is bonded with release paper through a viscose glue layer; the thickness of the release paper is 20 to 30 microns, wherein the anti-fogging layer is prepared from the following raw materials in parts by weight: 0.5 to 1.0 part of nano-titanium dioxide and 0.5 to 5 parts of polyurethane acrylate. The anti-fogging film prepared by the invention is obvious, lasting and effective in anti-fogging effect, has favorable machining properties and heat stability, has no special requirements on a matrix, is high in surface light transmissivity, strong in adhesive power and wide in range of application, and can be applied to surfaces of multiple matrixes of glass, metal, ceramic and the like.

Description

technical field [0001] The invention relates to an anti-fog film and a preparation method thereof, belonging to the field of polymer materials. Background technique [0002] In daily life, various substrates such as glasses, car window glass, bathroom mirrors, building interior and exterior window glass, agricultural greenhouses, etc., often appear fogging in places with high temperature difference or high humidity difference, which affects the use in life and production, and even It will cause a lot of loss of manpower and material resources. For example, when wearing glasses in winter and entering a higher temperature room from a lower temperature outdoor, a layer of fog will inevitably be produced on the lens, which will affect normal actions; Fog affects the driver's driving; in addition, agricultural greenhouses are often fogged due to the evaporation of water vapor in the shed, which affects the sunlight intake of the plants in the shed, thereby affecting the normal g...
