Problems solved by technology

[0003] However, the solar heat insulation film currently used in the market is prone to bubbles when pasted, which is not easy to discharge, which affects the aesthetics of the product after the film is pasted, and the solar heat insulation film currently used has low light transmittance and poor scratch resistance. The surface is still easily scratched by hard objects such as fingers and pendants, and the surface of the film after the film is not both scratch-resistant and anti-fouling

Description

technical field [0001] The invention relates to a protective film, in particular to a solar thermal insulation film with anti-scratch and anti-fouling functions for protecting automobile glass and building exterior wall glass and a manufacturing method thereof. Background technique [0002] With the development of social economy, the vigorous rise of the automobile industry, and the growing construction industry, the automotive glass and building curtain wall glass are widely used. In order to prevent the glass surface from being scratched or worn and affect the use effect, a protective film with anti-scratch function is generally attached to the glass surface. [0003] However, the solar heat insulation film currently used in the market is prone to bubbles when pasted, which is not easy to discharge, which affects the aesthetics of the product after the film is pasted, and the solar heat insulation film currently used has low light transmittance and poor scratch resistance....
