Problems solved by technology

Although there are many kinds of heat insulation films, it is still difficult to have both high light transmittance and good heat insulation performance.
At present, although the light transmittance of domestic heat insulation film can reach 70%, the infrared light blocking rate does not exceed 55%, and the heat insulation effect is poor.

Abstract

The invention relates to a thermal-insulation window film and a preparation method thereof. The thermal-insulation window film is combined by multiple layers, wherein a thermal-insulation acrylic acid adhesive layer (3-1) is formed by a mixture of a thermal-insulation matter, an acrylic acid adhesive, a curing agent, an ultraviolet absorber, a dye, butanone and toluene in a mass ratio of (0.01-3.0):(9-60):(0.003-0.02):(0.001-0.015):(0-2):(5-24):(3-13); and the thermal-insulation matter is N,N,N',N'-tetrakis[4-(dibutylamino)phenyl]-1,4-cyclohexadiene-3,6-diaminium (1:2). The rate of the rejection to infrared light with a wavelength of 850 to 1,050 nanometers of the thermal-insulation window film is 96.7 percent, the light transmittance of the thermal-insulation window film is 71 percent, the rate of the rejection to ultraviolet light with a wavelength of 360 nanometers of the thermal-insulation window film is 99.9 percent, and thus, the rate of the rejection to infrared light with a wavelength of 850 to 1,050 nanometers of the thermal-insulation window film has high light transmittance and excellent ultraviolet-proof effect.

Description

technical field [0001] The invention relates to a heat-insulating window film and a preparation method thereof, which is particularly suitable for pasting on the surfaces of automobile glass windows and building door and window glass. Background technique [0002] Thermal insulation window film is a film material that selectively absorbs and effectively blocks the infrared light in sunlight. It is mainly used to paste on the surface of automobile glass windows and building door and window glass to achieve the effect of heat insulation and energy saving. Because it is non-polluting, convenient to mount and replace, it has broad market development prospects. Although there are many kinds of heat insulation films, it is still difficult to have both high light transmittance and good heat insulation performance. At present, although the light transmittance of domestic heat insulation films can reach 70%, the infrared light blocking rate does not exceed 55%, and the heat insulat...
