Abstract

본 발명은 자외선 차단용 무색유리 및 그 제품에 관한 것으로, 좀더 상세하게는 상기 유리는 63∼75wt% SiO2, 12∼25wt% R2o(여기서 R2O는 Na2O, K2O 및 Li2O중 적어도 1종 또는 2종이상으로 구성된다), 7∼12wt% RO, 0.25∼5wt% CeO2, 0∼3wt% Al2O3, 0.01∼0.06wt% Fe2O3, 0∼1wt% Sb2O3, 0∼0.001wt% Co2O4및 0∼0.005wt% Se의 조성으로 이루어지므로써 기존의 무색유리에 비해 색조에 있어 약간의 차이는 있으나 자외선 차단에 있어서 훨씬 우수한 성질을 가지며 이와 동시에 투명성을 유지할 수 있는 장점이 있기 때문에 무색의 자외선 차단용기, 자동차 유리 등 자외선에 노출되어 문제가 발생될 수 있는 모든 분야의 유리에 적용될 수 있는 잇점이 있다.The present invention relates to a colorless glass for UV protection and its products, more specifically, the glass is 63 to 75wt% SiO 2 , 12 to 25wt% R 2 o (wherein R 2 O is Na 2 O, K 2 O and Or at least one of Li 2 O), 7-12 wt% RO, 0.25-5 wt% CeO 2 , 0-3 wt% Al 2 O 3 , 0.01-0.06 wt% Fe 2 O 3 , 0- It is composed of 1wt% Sb 2 O 3 , 0∼0.001wt% Co 2 O 4 and 0∼0.005wt% Se, so there is a little difference in color tone compared to conventional colorless glass, but it is much better in UV protection. At the same time, there is an advantage that can be applied to all areas of glass that can cause problems due to exposure to ultraviolet rays, such as a colorless UV blocking container, automobile glass because it has the advantage of maintaining transparency at the same time.
