Problems solved by technology

Traditional enamel glaze porcelain needs to be fired twice after the carcass is painted with glaze, so it is a test for both the carcass and the enamel glaze, especially the area of ​​the enamel glaze may shrink or expand during firing. It may affect the appearance after firing, and a little carelessness will cause the enamel glaze to crack directly during firing

Abstract

The invention discloses an enamel glaze. The enamel glaze is prepared from, by weight, 100-150 parts of calcite, 100-120 parts of medical stone, 80-100 parts of cordierite, 60-80 parts of granite, 20-50 parts of kaolin, 10-30 parts of zinc oxide, 10-20 parts of yttrium oxide and 10-30 parts of zirconium oxide. The invention further discloses a preparation method of the enamel glaze. Compared with the traditional technology, the enamel glaze is scientific in formula and low in raw material cost; as the stability of the enamel glaze is better improved through secondary firing in the preparation process, the enamel glaze is suitable for glaze painting of various ceramic green bodies.

Description

technical field [0001] The invention belongs to the field of coatings, and in particular relates to an enamel glaze and a preparation method thereof. Background technique [0002] Enamel glaze porcelain is extended and developed from painted enamel handicrafts. The characteristics of enamel glaze are fine and moist porcelain, dignified glaze material, bright and beautiful color, and exquisite painting workmanship. Traditional enamel glaze porcelain needs to be fired twice after the carcass is painted with glaze, so it is a test for both the carcass and the enamel glaze, especially the area of ​​the enamel glaze may shrink or expand during firing. It may affect the appearance after firing, and a little carelessness will cause the enamel glaze to crack directly during firing. Contents of the invention [0003] Purpose of the invention: the purpose of the present invention is to provide a kind of enamel glaze for the deficiencies of the prior art. [0004] Another object of...
