GLASS COMPOSITION ABSORBING ULTRAVIOLET RAY AND INFRARED RAY AND APPLICATION THEREOF

摘要

An ultraviolet ray and infrared ray-absorbing glass composition includes the following basic glass components (weight ratio): 60% to 75% of SiO 2 , 8% to 20 % of Na 2 O, 3% to 12% of CaO, 0.1% to 5% of Al 2 O 3 , 2% to 5% of MgO, 0.02% to 7% of K 2 O, 0.1% to 5% of BaO, 0.01% to 0.4% of SO 3 and the following ultraviolet ray and infrared ray-absorbing glass main body coloring and coordinating part: 0.22% to 1.35% of Fe 2 O 3 , 0.001% to 0.8% of ZrO 2 +HfO 2 , 0% to 0.5% of Cl, 0% to 2% of B 2 O 3 , 0.01% to 0.8% of TiO 2 , 0.001% to 0.06% of CuO, 0% to 2.0% of Br, 0% to 0.02% of MnO, 0% to 2.0% of F, 0.001% to 0.5% of SrO, and 0.005% to 2.2% of CeO 2 . The reduction oxidation ratio of Fe 2 O 3 in the glass composition is 0.4 to 0.8. A certain amount of rare metals and rare earth metal compounds are added to the glass composition, which breaks through various limitations of existing insulating glass, reasonably controls the Chemical Oxygen Demand (COD) in raw materials, controls reduction oxidation ratios, effectively blocking ultraviolet rays, infrared ray and sunlight total energy while improving the transmittance of visible light to obtain insulating glass capable of intensively absorbing ultraviolet rays and near infrared rays.
