Abstract

The invention provides a window film adhered onto the outer side of a window glass. According to the invention, a thermal insulation layer is arranged on the surface of a transparent substrate, and a scratch-resistant and weather-resistant layer is arranged on the surface of the thermal insulation layer; the other surface of the transparent substrate is provided with a pressure-sensitive adhesive layer, and a release film layer is arranged on the surface of the pressure-sensitive adhesive layer. The window film provided by the invention has a simple structure, excellent aging resistance, a high ultraviolet light rejection rate and high thermal insulation efficiency and can be widely applied to window glass of a building or an automobile.

Description

technical field [0001] The invention relates to a window film, in particular to a window film adhered to the outside of the window glass. Background technique [0002] Window film is an energy-saving and environmentally friendly film product with broad market development prospects. It is mainly used in automobile windows and building windows. [0003] In many cases, due to the limitation of construction location or site, it is impossible to attach window film to the inner side of the glass window, such as ceiling glass, glass curtain wall, multi-layer glass, and hollow glass structures that require higher energy-saving effects, etc. Window film is attached on the outside. Because it is used on the outside of glass windows, it is required to be used for a long time and has excellent aging resistance, that is, it will not be embrittled within a certain period of time (more than 8 years). However, the existing known window films are generally used on the inside of the glass w...
