Problems solved by technology

This process is to make bone china by applying thin glaze on the plain embryo, which is similar to the painting process in glaze, and the glaze layer will be formed after adding glaze and firing, which is not conducive to painting, and the clarity of the pattern of the product is not ideal. Not strong sense of hierarchy

Abstract

The invention discloses underglaze color bone porcelain and a preparation method thereof, and relates to the technical field of ceramic preparation. According to the invention, montmorillonite is modified, so that the compression resistance and impact resistance of the bone porcelain are enhanced, and the adsorption rate of the bone porcelain on pigment and glaze is improved to ensure that patterns on the bone porcelain are clear, the layering feeling is strong, and fading is not easy; and a dispersant has a good stabilizing and dispersing effect on each component raw material, and can improvethe combination degree of the component raw materials, so that the prepared bone porcelain is uniform, compact and easy to color. The raw materials selected for the bone porcelain provided by the invention are cheap and easy to obtain and do not cause pollution to the environment; meanwhile, a three-time sintering process is adopted, so that the sintering rate of the product is greatly improved.

Description

Technical field: [0001] The invention relates to the technical field of ceramic preparation, in particular to an underglaze colored bone china and a preparation method thereof. Background technique: [0002] Bone China is a world-recognized high-grade porcelain. Bone china is milky white and translucent. The product is extremely light. The glaze is smooth, bright and lubricated. At present, bone china mainly adopts the traditional production process of overglaze color for decoration. Because of the complicated firing technology of underglaze color bone china, it is difficult to produce high-quality underglaze color bone china. [0003] The Chinese patent publication number is CN101121601A, and the disclosure date is February 13, 2008. The title of the invention is the bone china underglaze color process, and the application discloses a bone china underglaze color process. The technology disclosed in this application discloses that underglaze color products of bone china ca...
