preparation example Construction

[0037] A preparation method of matte black glaze, used for the matte black glaze of any of the above-mentioned embodiments, is characterized in that, comprises the following steps:

[0038] Put lithium petalite, fused quartz, halloysite, calcined talc, barium carbonate, calcined zinc oxide, zirconium silicate, dolomite and calcite into the ball mill according to the proportion, add water and ball milling agent, and ball mill until the residue on the 325 mesh sieve is less than 0.05% Finally, add high-cobalt black pigment and continue ball milling, out of the ball, adjust the specific gravity to 1.60-1.90, and sieve to obtain matte black glaze.

[0039] A matte black sanitary ware, the surface of the sanitary ware is provided with a matte black glaze layer; the glaze layer is fired from the above matte black glaze.

[0040]General sanitary ware is mainly made of ceramics, glass fiber reinforced plastics, plastics, artificial marble (agate), stainless steel and other materials. ...

Embodiment A1

[0055] Preparation method of matte black glaze:

[0056] 1) Matte black glaze, its specific addition is shown in Table 1. Among them, the content of petalite K 2 O is 0.3%, Na 2 O content is 0.2%, SiO of fused silica 2 The aluminum content of halloysite is 99.5%, and the aluminum content of halloysite is 37.2%. The high-cobalt black pigment is fired at 1300°C, and the composition is CoO 30%, NiO 15%, Fe 2 o 3 40%, Cr 2 o 3 15%, and its 325-mesh sieve is 0%. Put all the raw materials except the high-cobalt black pigment into the ball mill according to the ratio, add water and 0.2% sodium carboxymethyl cellulose of the total amount of materials, and ball mill until the 325-mesh sieve is less than 0.05%, then add high-cobalt black color The material was continued to be ball-milled for 1 hour, the balls were taken out, the specific gravity was adjusted to 1.80, and the matte black glaze was obtained by passing through a 160-mesh sieve.

[0057] 2) On the pre-treated sani...

Embodiment B

[0065] Matte black glaze, its composition mass percentage is: Lithium feldspar 30%, fused quartz 20%, halloysite 6%, calcined talc 21%, barium carbonate 2%, calcined zinc oxide 1%, zirconium silicate 2% %, dolomite 5%, calcite 6% and high cobalt black pigment 7%. Among them, the content of petalite K 2 O is 0.3%, Na 2 O content is 0.2%, SiO of fused silica 2 The aluminum content of halloysite is 99.5%, the aluminum content of halloysite is 37.2%, and the high-cobalt black pigment is fired at 1300°C, and the composition is CoO 30%, NiO 15%, Fe 2 o 3 40%, Cr 2 o 3 15%, and its 325-mesh sieve is 0%.

Abstract

The invention relates to matte black glaze and sanitary ware and preparation methods and application thereof, belonging to the field of ceramics. The matte black glaze comprises the following raw materials: petalite, fused quartz, halloysite, calcined talc, barium carbonate, calcined zinc oxide, zirconium silicate, dolomite, calcite and high-cobalt black pigment. The preparation method of the matte black glaze is used for preparing the matte black glaze. A matte black glaze layer is arranged on the surface of the matte black sanitary ware. The preparation method of the matte black sanitary ware is used for preparing the matte black sanitary ware. The matte black glaze is used for the sanitary ware; the glaze is well combined with a green body; and after high-temperature sintering, the matte black glaze has acid and alkali resistance, water washing resistance and organic solvent resistance, is free of the quality problem of fading, and overcomes the problem that matte smooth ware is formed by conducting paint spraying and secondary processing on common bright emulsion-white glaze sanitary ware in the prior art.

Description

technical field [0001] The invention relates to the technical field of sanitary ware glaze, in particular to a matte black glaze, sanitary ware, a preparation method and application thereof. Background technique [0002] The used glaze material of existing sanitary ware is relatively monotonous, mainly is light milky white glaze. With the development of society, Chinese people have more and more personalized demands for sanitary ware products, and the aesthetics of interior decoration are more and more diversified, which has given birth to the market demand for matte sanitary ware products. Most of the matte sanitary ware on the market today is made of ordinary bright milky white glaze sanitary ware for secondary painting, and has poor wear resistance, acid and alkali resistance, and organic solvent resistance, and has defects such as easy fading after long use. Promote the popularity of matte sanitary ware products, but make consumers discouraged from matte sanitary ware p...
