Problems solved by technology

[0003] Window film has gone through four eras since its production and use: the first generation: coating and composite process film, its main function is to block strong sunlight, this product does not have heat insulation, it is only used for shading , the clarity is extremely poor; the second generation: dyed film, using deep dyeing process, adding heat absorbing agent components, absorbing infrared rays in sunlight to achieve heat insulation effect, this product has low visible light transmittance and heat insulation function attenuation Disadvantages such as fast and easy to fade; the third generation: vacuum thermal evaporation film, which uses vacuum evaporation process to evaporate the aluminum layer on the PET substrate to achieve a certain heat insulation effect, but its weakness is low clarity and high reflection High, easy to cause visual fatigue and cause accidents; the fourth generation: magnetron sputtering film: using vacuum magnetron sputtering technology, compared with the previous three generations of technology, the window film prepared by this technology has a qualitative leap, its disadvantages The preparation process is complex and the product cost is high

Abstract

An anti-ultraviolet high-heat-insulation window film is provided with a scratch resisting layer, a transparent thin film base material layer, a heat insulation layer, an ultraviolet blocking layer, a pressure-sensitive adhesive bonding layer and a release film layer, wherein the scratch resisting layer is arranged on one surface of the transparent thin film base material layer through ultraviolet light curing, the heat insulation layer is arranged on the other surface of the transparent thin film base material layer through ultraviolet light curing, the ultraviolet blocking layer is arranged on the outer surface of the heat insulation layer through heat curing, the pressure-sensitive adhesive bonding layer is arranged on the outer surface of the ultraviolet blocking layer through heat curing, and the release film layer is compounded on the outer surface of the pressure-sensitive adhesive bonding layer. The heat insulation layer is formed by coating, drying and curing coating liquid consisting of an ultraviolet light coating and a nanoscale metal oxide. The anti-ultraviolet high-heat-insulation window film is simple in preparation process, high in ultraviolet light blocking rate and capable of being applied to building windows or automobile windows.
