Abstract

The invention relates to a frit suitable for color development as well as a colored vitreous enamel product and a preparation method. The frit suitable for color development comprises the following components in parts by weight: 20-35 parts of feldspar, 10-45 parts of quartz, 0.5-5 parts of Suzhou clay, 2-6 parts of calcium borate, 1-7 parts of aluminium hydroxide, 12-32 parts of light calcium carbonate, 1-8 parts of barium carbonate, and 1-8 parts of borax. The preparation method for the colored vitreous enamel product comprises the following steps: (1), preparing enamel slurry; (2), enameling the product; (3), sintering. The colored vitreous enamel product comprises an inner enamel layer and an outer enamel layer, wherein the ceramic carcass is high-end ceramic, the inner enamel layer is a transparent frit enamel layer, and the outer enamel layer is a colored enamel layer made from the frit suitable for color development. The frit suitable for color development is appropriate in frit expansion factor, relatively wide in sintering range, bright and flat in enamel surface, and can be used for various colored decoration of various high-end ceramic products. The preparation method of the colored vitreous enamel product and the colored vitreous enamel product can be used for producing various high-end enamel products for hue decoration.

AI Technical Summary

Problems solved by technology

[0008] At present, due to the difference in porcelain quality and expansion coefficient of various high-grade porcelain products fired twice, the surface glaze frits used are different. In view of the different requirements of various ceramic pigments on the basic glaze, and the brightness of the glaze, Due to technical factors such as firing temperature, the color glaze decoration of high-grade porcelain is quite complicated, especially the difficulty of serialized decoration is more complicated and difficult.
