Ultraviolet/infrared absorbent low transmittance glass |
摘要 |
An ultraviolet/infrared absorbent low transmittance glass is formed of a base glass and colorants. The base glass contains 65 to 80 wt. % SiO2; 0 to 5 wt. % Al2O3; 0 to 10 wt. % MgO; 5 to 15 wt. % CaO wherein a total amount of MgO and CaO is between 5 and 15 wt. %; 10 to 18 wt. % Na2O; 0 to 5 wt. % K2O wherein a total amount of Na2O and K2O is in a range of 10 and 20 wt. %; and 0 to 5 wt. % B2O3. The colorants contains more than 1.2 wt. % and not more than 1.5 wt. % total iron oxide (T-Fe2O3) expressed as Fe2O3; equal to or more than 0.003 wt. % and less than 0.015 wt. % CoO; 0.0009 to 0.005 wt. % Se; 0.0005 to 0.05 wt. % NiO; and 0 to 0.2 wt. % of TiO2, wherein FeO expressed as Fe2O3 is between 15 and 50 wt. % of T-Fe2O3. The ultraviolet/infrared absorbent low transmittance glass has a bronze or gray color shade, low visible light transmittance, low solar energy transmittance and low ultraviolet transmittance, so that it is useful for a privacy protecting glass in a rear window of a vehicle.
