(57) [Summary] [Purpose] To provide a method for producing an ultraviolet blocking glass having excellent scratch resistance and abrasion resistance, which is suitable for window glass for automobiles and buildings. [Constitution] Zinc oxide fine powder having a particle size of 0.1 μm or less, SiO 2 /ZnO=0.2 in the organopolysiloxane solution Mix to a ratio of 5 to 0.67 (weight ratio). Next, the liquid obtained by dispersing the zinc oxide fine powder is applied to a plate glass so as to have a dry film thickness of 0.2 to 1.5 μm. Then, this plate glass is heated to 580 to 700 ° C. The glass is fired to manufacture an ultraviolet blocking glass. Moreover, the window glass for automobiles and the window glass for construction which consists of the obtained ultraviolet-shielding glass. |
