Nanometer intelligent thermal insulating window film

Abstract

The invention relates to a nanometer intelligent thermal insulating window film which is composed of an anti-scratch layer (1), a polyester film or polycarbonate film base material (2-1), an intelligent thermal insulating glue layer (3), a polyester film or polycarbonate film base material (2-2) with a metal coating, an ultraviolet blocking pressure-sensitive glue layer (4) and a release film (5). The anti-scratch layer (1) is combined with one surface of the polyester film or polycarbonate film base material (2-1), the intelligent thermal insulating glue layer (3) is combined with the other surface of the polyester film or polycarbonate film base material (2-1), the surface of the metal coating of the polyester film or polycarbonate film base material (2-2) with the metal coating is located on the outer surface of the intelligent thermal insulating glue layer (3), the ultraviolet blocking pressure-sensitive glue layer (4) is combined with the other surface of the polyester film or polycarbonate film base material (2-2) with the metal coating, and the release film (5) is located on the outer surface of the ultraviolet blocking pressure-sensitive glue layer (4). The nanometer intelligent thermal insulating window film has a low radiation rate and high visible light transmittance.

Description

technical field [0001] The invention specifically relates to a nano intelligent heat-insulating window film, which is particularly suitable for pasting on the glass surface of a building or a car. Background technique [0002] According to statistics, building energy consumption accounts for about one-third of the total energy consumption of the society, and building windows are an important part of the building envelope. Studies have shown that the energy consumption loss of windows accounts for the entire building. About 50% of the energy loss of the enclosure structure. Renovation of windows and curtain walls is the key to building energy conservation. There are only two options for the green transformation of glass in existing buildings: one is to remove the original glass and replace it with energy-saving glass; insulation film. In the first method, removing the original glass will not only cause a large amount of construction waste, but also the cost of replacing the...

Problems solved by technology

However, the base film in its product structure is a common base film. Therefore, the radiation rate is relatively high. In the environment with heating facilities in winter, there will be large heat radiation and cause heat loss. It is not suitable for the climate in the north where the winter is cold and the summer is hot.

[0005] The application number is 200810033032.6 Chinese patent discloses an intelligent thermal insulation film and its preparation method, but its structure is a single-layer structure, the weather resistance cannot be guaranteed, and the adhesion of the coating to the surface of the substrate is also problematic, and it is wear-resistant and scratch-resistant Poor performance, and at the same time, there will be problems in its construction in practical applications

[0006] The application number is 201410568704.9 Chinese patent discloses the temperature control window film and the preparation method of the temperature control window film, which adopts the dry coating method, that is, the magnetron sputtering method, which requires multiple sputtering on the flexible substrate, and the production process Complex, high cost, and the adhesion of the coating on the substrate cannot be guaranteed. The temperature-controlled window film cannot be used directly on the glass, and it needs to be glued before it can be pasted on the glass.
