Problems solved by technology

Traditional enamel colored porcelain needs to be fired twice after painting on the carcass, so it is a test for both the carcass and the enamel color, especially the area of ​​the enamel color may shrink or expand during firing, which may affect the firing The final look and feel, and a little carelessness will cause the enamel to crack directly during firing

Abstract

The invention discloses color enamel. The color enamel is prepared from the following components in parts by weight: 100 to 150 parts of potassium feldspar, 100 to 120 parts of medical stone, 80 to 100 parts of cordierite, 60 to 80 parts of quartz, 10 to 30 parts of zinc oxide and 10 to 40 parts of calcium oxide. Meanwhile, the invention further discloses a preparation method of the color enamel. Compared with a conventional technology, the color enamel is scientific in formula and low in raw material cost; secondary sintering is carried out in a preparation process so that the stability of the color enamel is greatly increased and the color enamel is suitable for colored drawing of various ceramic blanks.

Description

technical field [0001] The invention belongs to the field of coatings, and in particular relates to an enamel color and a preparation method thereof. Background technique [0002] Enamel colored porcelain is extended and developed from painted enamel handicrafts. The characteristics of enamel colored porcelain are fine and smooth porcelain, dignified color materials, bright and beautiful colors, and exquisite painting skills. Traditional enamel colored porcelain needs to be fired twice after painting on the carcass, so it is a test for both the carcass and the enamel color, especially the area of ​​the enamel color may shrink or expand during firing, which may affect the firing The final look and feel, and a little carelessness will cause the enamel 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 color for the deficiencies of the prior art. [0004] Another o...
