preparation example Construction

[0035] The present invention also provides a kind of preparation method of ceramic product, comprises the following steps:

[0036] (1) Add each raw material of the base glaze of the matt color glaze mixed with waste porcelain powder and the additional coloring material into a ball mill according to the formula ratio and carry out wet ball milling to obtain the glaze slurry. The content of particles below 10 μm in the glaze slurry is 75-85%;

[0037] (2) Applying the glaze slurry obtained in step (1) to the surface of the molded body by spraying glaze;

[0038] (3) into the kiln and fired.

[0039] The preparation method of the ceramic product of the present invention has the characteristics of simple process and easy control, and can obtain the ceramic product with stable glaze color and positive color development. Preferably, the ceramic product is a sanitary ware.

[0040] Further, in step (1), during wet ball milling, the weight ratio of the ball-into raw material and w...

Abstract

The invention discloses a waste ceramic powder doped matt color glaze, a ceramic product, a preparation method of the ceramic product and a glaze. The formula of the basic glaze comprises the following raw materials in parts by weight: 15-30 parts of potassium feldspar, 4-10 parts of calcined talc, 5-10 parts of kaolin, 3-7 parts of calcined zinc oxide, 20-30 parts of quartz powder, 6-16 parts ofcalcite, 0-6 parts of dolomite, 0-8 parts of zirconium silicate and 5-20 parts of waste porcelain powder. The glaze surface of a ceramic product fired by adopting the glaze material is a matt glaze surface, and the color is normal, uniform and stable.

Description

technical field [0001] The invention relates to the technical field of ceramics, in particular to a dull colored glaze mixed with waste porcelain powder, a ceramic product and a preparation method. Background technique [0002] Matte glaze refers to the glaze with mercerized or jade-like luster without strong reflection of light. This kind of glaze can get better effect when applied on floor tiles, wall tiles or sanitary ware. [0003] Most of the existing matte glazes are white matte glazes, and most of them are calcium, magnesium, barium and zinc systems. The matte color glaze is obtained by adding a certain amount of coloring material to the white matte glaze as the base glaze. The preparation of matt white glaze is relatively easy, but after adding pigment to the white matt glaze as the base glaze, the color of the glaze after firing will be unstable with fluctuations in the kiln, which will affect the quality of ceramic products. Contents of the invention [0004] T...
