AI Technical Summary

Problems solved by technology

The production process of these films is generally more complicated, and may involve technologies such as multi-layer sputtering, dipping dyeing, and co-extrusion, so it is difficult to adjust the color and light transmittance of the heat insulation film.
Although the color of the thermal insulation film can be adjusted by using dyed adhesive or colored hard coating, the stability and anti-aging performance of the thermal insulation film will be deteriorated, and the infrared blocking effect and light transmittance will be poor

Abstract

The invention provides a mixture of nanoparticles, including at least two of the first composite metal oxide nanoparticles, carbon black nanoparticles and the second composite metal oxide nanoparticles. The present invention also provides a polymer comprising a mixture of nanoparticles, wherein the ratio of the weight of the mixture of nanoparticles to the weight of the polymer particles is less than 0.85. The invention also provides a sticking film containing a polymer, and a heat insulation film containing a mixture of nanoparticles. According to the nanoparticle mixture provided by the present invention, the polymer, the sticking film and the thermal insulation film can be applied to automobile glass, architectural windows or other products that need to block infrared light, so that these automobile glass, architectural windows and products that need to block infrared light not only have Excellent infrared blocking performance, and their color tone, optical properties (such as visible light transmittance), haze and other properties can also be adjusted according to needs.

Description

technical field [0001] The invention relates to a nanoparticle mixture and a polymer, and also relates to a pasting film and a thermal insulation film applicable to automobile glass and building windows. Background technique [0002] Heat insulation film is widely used in automobile glass and building windows to block ultraviolet rays and heat in sunlight, improve the comfort in cars and houses, adjust the color of windows, protect privacy, and prevent splashes after glass breaks, etc. Typical heat insulation films include dyed films, metal heat insulation films and ceramic films. The production process of these films is generally more complicated, and may involve technologies such as multi-layer sputtering, dip dyeing, and co-extrusion, so it is difficult to adjust the color and light transmittance of the heat insulation film. Although the color of the thermal insulation film can be adjusted by using dyed adhesive or colored hard coating, the stability and anti-aging perfo...
