Abstract

The invention belongs to the technical field of an inorganic amorphous material, and particularly relates to a leadless, cadmium-free and strontium-free transparent colored glass component and a manufacture process thereof. The transparent colored glass component is characterized by only containing conventional oxides, such as SiO2, B2O3, ZnO, CaO, BaO, Na2O, K2O and the like without containing lead, cadmium or strontium which has great toxic effect. The invention has the advantages that: a decolorizing agent is added into the leadless, cadmium-free and strontium-free basic component to prepare a colorless transparent glass product; various coloring agents are added into the leadless, cadmium-free and strontium-free basic component to obtain the colored glass. Equipment or investment is not additionally increased, the glass product with good color, low softening point and long material property can be produced only by adopting existing raw material treatment, melting furnaces, hot melting furnaces, annealing furnaces, cold machining and other equipment, and the cost of the transparent colored glass is reduced by 2 to 4 times than that of conventional medium-lead and high-lead glass. The invention has wide application prospect.

Description

technical field [0001] The invention relates to a colored glaze composition and a preparation process, in particular to a colored glaze composition free of toxic metals lead, cadmium and strontium and a manufacturing process of its products. Background technique [0002] Glass is a kind of silicate product with a long history. Its quality is crystal clear, dazzling and magnificent, which can fully reflect the delicacy, delicacy and subtlety of the oriental people. It is an important decorative component in architecture and an important part of art decoration. A wonderful flower. Because the glass composition containing lead silicate has good gloss, long material properties and low softening point, it is especially suitable for the glass manufacturing process. The glass has always been made of medium-lead or high-lead crystal glass, and the lead element and its compounds are harmful to the environment. It is extremely harmful to human health, so there are some patents on the...
