Color ceramic and color frit composition for automobile glass plate

Abstract

Abstract PURPOSE: To obtain a color ceramic and color frit composition for automobile glass plate having less decrease of the strength than the conventional products and consisting of a glass powder composed of a heat-resistant color pigment and SiO 2 as specific components and specific proportions of a glass powder, Zr, and a low- expansible fire-proof filler and the like. CONSTITUTION: The color ceramic and color frit composition for automobile glass plate consists of a low-melting glass powder containing 10W40wt% SiO 2 , 1W 15wt% Al 2 O 3 , 3W51wt% ZnO, 10W35wt% B 2 O 3 , 1W20wt% Na 2 O+K 2 O+Li 2 O, 0.5W35wt% MgO+CaO+BaO, 0W5wt% TiO 2 +SnO 2 , and 0W2wt% F, a well- known heat-resistant color pigment powder, e.g., MnO 2 , etc., and a low-expansible fire-proof filler powder composed of at least one of Zn and Al 2 O 3 , 75W99pts.wt. a glass powder, and 25W1pts.wt. a filler powder. The composition has a high mechanical strength after being baked and is almost free of the lowering of strength of glass. Thus, the composition is most suitable for the window panes of automobile, etc. COPYRIGHT: (C)1981,JPO&Japio
