Abstract

The invention belongs to the technical field of ceramic glazes, and relates to a metal glaze and a preparation method and an application method thereof; the weight percentages of each raw material in the metal glaze are: 30-37% albite, 8-15% quartz, 0-4 % wollastonite, 9-16% calcined kaolin, 4-6% calcined zinc oxide, 19-23% calcined iron phosphate, 13-20% self-made high phosphorus frit powder. On the basis of calcined iron phosphate, the metal glaze adds self-made high-phosphorus frit powder as a crystallization accelerator to make the metallic luster easier to appear, and the self-made high-phosphorus frit powder introduces P element in the form of frit, compared with High-phosphorus raw material system, the self-made high-phosphorus frit powder has a wider firing temperature range, making the metal effect more stable; by fine-tuning the ratio of the self-made high-phosphorus frit powder and silicon-aluminum glaze, that is It can realize the adjustment of metal effects of different colors. In addition, the metal glaze is combined with a roller printing process, which can make the glaze surface present a good three-dimensional effect.

Description

technical field [0001] The invention relates to the technical field of ceramic glazes, in particular to a metal glaze, a preparation method and an application method thereof. Background technique [0002] Decorative metal materials are highly sought after by consumers because of their gorgeous and precious decorative styles, but their high price and poor acid and alkali resistance limit their application scenarios. With the innovation of preparation technology of decorative materials, architectural ceramics with metallic effects are widely used because of their realistic metallic luster and excellent corrosion resistance. [0003] Among them, the metal glaze is a special crystal glaze. There are four methods of preparing metallic glazes in the ceramic industry: coating pyrolysis and imitation gold technology, thermal spraying, evaporation and sintering. The sintering method is the most common method for preparing metallic glazes. Usually, transition metal oxides (such as C...
