Application of Nanometer Metal Oxides in Infrared Ray Shielding Transparent Thin Film

Abstract:

Water-based infrared ray shielding coating, that is, nanometer metal oxide is added to the water-based paint, which has anti-IR features without affecting the transparency of the paint. In this paper, the nanometer oxides are prepared by sol-gel method, added into polypropylene sour. In order to improve the infrared ray shielding of the thin film, two kinds of nanometer oxides are added into the polypropylene sour with different volume ratios, the shielding performance of the paint is studied. Experimental results show: in the 8000 ~ 4000cm^-1 range, the transmittances of infrared ray is 30% to 75%; in 4000 ~ 400cm^-1 range, transmittances decrease significantly; 3% ZnO, 3% Fe₂O₃, 3% Y₂O₃, 2% Al₂O₃ are the best mass ratio of every single nanometer oxide; the infrared shielding rate of Fe₂O₃ and Y₂O₃ mixture with the volume ratio of 1 to 4 is better than Fe₂O₃ and Y₂O₃ single.
