Abstract

The invention belongs to the technical field of ceramic decoration and particularly relates to underglaze pigment as well as a preparation method and application thereof. The underglaze pigment comprises a coloring material, a color aid and a lubricating agent, and the fact that the underglaze pigment has the advantages of good color development, high lubricating property, smooth writing, high strength, insusceptibility to breakage and the like can be guaranteed by controlling the proportion of the components; meanwhile, through the proportion of the components, the underglaze pigment has highhydrophilicity and is favorable for glazing the surface of a green body after drawing, the handwriting of the pigment has high hydrophilicity with the glaze, and the fired China Flower has bright andclean color and smooth line. The fact that the color is clear and bright can be guaranteed by controlling the use amount of the color aid; the color shade of the China Flower can be adjusted by controlling the use amount of the coloring material; and through control on the use amount of the lubricating agent, the lubricating property of the pigment is improved and writing is facilitated while thecolor of the pigment is not influence.

Description

technical field [0001] The invention belongs to the technical field of ceramic decoration, and in particular relates to an underglaze color pigment and its preparation method and application. Background technique [0002] Blue and white porcelain, also known as white ground blue and white porcelain, or blue and white for short, is one of the mainstream varieties of Chinese porcelain. Blue and white is one of the high-temperature underglaze colored porcelains. It uses cobalt oxide-containing cobalt ore as raw material to paint patterns on the porcelain carcass, then apply transparent glaze, and calcined in a high-temperature reducing atmosphere. [0003] Traditional blue-and-white painting needs to go through processes such as grinding blue-and-white materials, dividing water, drawing lines with brushes, coloring, glaze, and high-temperature firing. "Water separation process" is an important technique for painting blue-and-white decorations. According to the needs of the pic...
