Abstract

The present invention relates to a solar control film, wherein a titanium nitride film is plated on a substrate PET in a magnetron sputtering manner, a thickness of the substrate PET is 23-50 mum, a thickness of the titanium nitride film is 5-30 nm, and the titanium nitride film is plated by using a medium frequency reaction twin target magnetron sputtering method. The present invention further relates to a double layer composite solar control film, wherein two layers of solar control films are adhered through a pressure sensitive adhesive layer, and the pressure sensitive adhesive layer is positioned between the titanium nitride films of the two layers of the solar control films. The films of the present invention have the following characteristics that: infrared rays are blocked so as to reduce heat source; an anti-reflection effect can be provided in a visible light region, such that thermal insulation is achieved while transmittance on visible light is not affected; TiN has characteristics of high chemical stability at a room temperature, stable performance, no fading, no discoloration, and long service life; and glass splashing after breakage can be prevented, such that a function of explosion resistance is provided. In addition, with the double layer composite solar control film, reflected light intensity can be effectively reduced.

Description

technical field [0001] The invention relates to a solar control film, in particular to a solar control film used for automobiles and buildings, which can insulate heat without affecting the transmittance of visible light. The invention also relates to a double-layer composite solar control film made by using the solar control film. Background technique [0002] With the shortage of energy and the aggravation of environmental pollution, the demand for new energy and new materials has become increasingly prominent, and at the same time, higher requirements for energy conservation and emission reduction have also been put forward. In the solar spectrum range, infrared rays are the main spectral lines that carry heat energy. Therefore, blocking infrared rays reduces the source of heat. The early solar control films were dyed films, which were mainly used to achieve strong light control, that is, sunshade, and block part of the sun's heat; dyed films mainly control the transmitt...
