Abstract

The invention belongs to the field of optical film, and more specifically relates to a high reflectivity multilayer heat insulation window film which his high in reflectivity on infrared light, and apreparation method thereof. The high reflectivity multilayer heat insulation window film comprises a PET sealing layer, a first reflecting layer, a second reflecting layer, a third reflecting layer, afourth reflecting layer, a fifth reflecting layer, a sixth reflecting layer, a seventh reflecting layer, an eighth reflecting layer, a ninth reflecting layer, a tenth reflecting layer, an eleventh reflecting layer, a twelfth reflecting layer, a thirteenth reflecting layer, a fourteenth reflecting layer, and a PET substrate layer, which are laminated successively, and is prepared through magnetronsputtering. The high reflectivity multilayer heat insulation window film is invented based on optical interference enhancing principles, reflective constructive interference of light of different wavelengths in infrared light is realized, so that transmission effect is reduced, high reflective effect on infrared light (800 to 1500nm) is achieved, and the transmittance is only 8%.

Description

technical field [0001] The invention belongs to the field of optical films, and in particular relates to a multilayer heat-insulating window film with high reflection effect on infrared light and a preparation method thereof. Background technique [0002] Ultraviolet rays in sunlight include UVC (200-280nm), UVB (280-320nm), UVA (315-340nm), and UVA+. In addition to UVC being absorbed by the ozone layer and unable to reach the surface of the earth, others can cause melanin deposition on human skin and deepen the color. Excessive ultraviolet exposure can cause skin cancer and cause carpets, curtains, fabrics and furniture paint to fade. The visible spectral band is between 380nm and 780nm in wavelength, which is the part of the electromagnetic spectrum that can be perceived by the human eye. According to different wavelengths, the human body can perceive different colors (that is, red, orange, yellow, green, blue, indigo, and violet), and there is no direct harm to the human ...
