Abstract

The invention discloses a multifunctional nanometer film. First composite glue coats the upper surface of a first layer PET based film; second composite glue coats the portion between the first PET based film and a second PET based film, an installation layer acrylic acid glue coats the lower surface of the second PET based film; a third layer PET release film is attached to the lower surface of the installation layer, and the release layer adopts a polyester film obtained after low-energy treatment. The multifunctional nanometer film has multiple functions of resisting bacteria, preventing mold, preventing fog, preventing static electricity, thermal phase transition, color phase transition, resisting ultraviolet rays, insulating sound, preventing explosion and the like, can be widely used for the surfaces of window glass of automobiles, buildings and the like, energy conservation, environment protection and safety protection effects can be achieved, and the comfort degree can be improved. The invention further discloses a preparation method of the multifunctional nanometer film.

Description

technical field [0001] The invention relates to a multi-functional nano-film, especially a multi-functional nano-film with multiple functions such as antibacterial, anti-mildew, anti-fog, anti-static, thermal phase change, color phase change, anti-ultraviolet, sound insulation, explosion-proof, etc. In addition, the invention also discloses a preparation method of the aforementioned multifunctional nanometer film. Background technique [0002] Solar insulation film is a common energy-saving material, usually used in construction, automobile and other industrial fields. At present, the common solar film on the market is mainly composed of 5 parts, including surface anti-scratch coating, PET substrate layer, composite layer, installation layer, and release film layer. The anti-scratch layer on the surface is usually formed by UV-curable coatings. The composite layer is usually added with nano-insulation media such as ATO and ITO and ultraviolet absorbers. The surface of the P...
