Problems solved by technology

However, because lead is a heavy metal, it will not only cause environmental pollution during production and affect the health of operators, but also the resulting glaze has poor wear resistance and is easily scratched
In addition, lead will also dissolve during actual use, so it is difficult to further promote it in catering ceramics

Abstract

The invention discloses lead-free metal luster gold glaze and a preparation method thereof. The lead-free metal luster gold glaze is prepared from the following ingredients in percentage by mass: 65 to 75 percent of basic glass fused blocks, 10 to 20 percent of MnO2, 1 to 10 percent of CuO, 1 to 10 percent of TiO2 and 1 to 5 percent of NiO. The preparation method comprises the following steps thatbasic glass fused block powder and inorganic oxide powder are added into a ball mill tank; ball milling is performed to prepare black glaze slurry; the black glaze slurry is glazed on the blank bodysurface in a spraying, coating or glaze pouring mode; drying is performed; then, the glazed blank body is fired at high temperature under the oxidizing atmosphere; heat insulation is performed; a metal glaze building ceramic product with metal luster and gold decoration effect can be obtained. A traditional ceramic glaze preparation technology is used; the gold decoration ceramic glaze with good metal luster can be obtained; the characteristics of wide firming range, stable color appearance, high surface hardness, no lead pollution in the preparation process and the like are realized; the lead-free metal luster gold glaze can be safely used for surface glaze layer decoration of tableware ceramics.

Description

technical field [0001] The invention belongs to the technical field of material science, and in particular relates to a lead-free metallic luster golden glaze and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, people's demand for home decoration appreciation is getting higher and higher. Today, ceramic products with metallic luster decorative glazes have artistic effects such as elegance, luxury and antiques on the market, so they are increasingly favored by consumers. At present, the preparation methods of metallic luster glazes at home and abroad are mainly divided into three types: sputtering melting method, that is, directly sputtering molten metal coating on the surface of ceramic substrate to obtain products with final metal decorative effect; second, sputtering molten metal coating on the surface of ceramic substrate The surface is sprayed with metal oxide powder, and then reduced and sintered to form a ...
