Embodiment 1

[0024] A kind of brown ceramic pigment, the parts by weight of each component are:

[0025] 0.255 parts of manganese dioxide, 0.4 parts of ferric oxide, 0.5 parts of silicon dioxide, 5 parts of zinc oxide, 25 parts of urea, 0.1 parts of sodium fluoride, and 5 parts of sodium fluorosilicate.

[0026] Its preparation method comprises the following steps:

[0027] Mix and stir the raw materials evenly to obtain a uniform mixture, then grind it thoroughly for 1 hour; calcinate the mixture at 600°C for 8 hours; after calcining, add the powder into pure water that is 30 times its weight, stir for 30 minutes, and filter out the water and drying; the dried solid is ground by a ball mill and passed through a 300-mesh sieve to obtain a brown ceramic colorant.

Embodiment 2

Abstract

The invention relates to a coffee ceramic pigment and a preparation method thereof and belongs to the technical field of preparation of ceramic pigments. The coffee ceramic pigment comprises the following components in parts by weight: 0.1-0.3 part of manganese dioxide, 0.3-0.5 part of iron oxide, 0.5-1 part of silicon dioxide, 5-10 parts of zinc oxide, 25-35 parts of urea, 0.1-0.5 part of sodium fluoride and 5-10 parts of sodium fluosilicate. The preparation method comprises the following steps: uniformly mixing and stirring raw materials to obtain a uniform mixture, and then fully grinding the uniform mixture for 1-2 h; calcining the mixture for 8-10 h at 600-650 DEG C; after calcination, adding the calcined powder into purified water which is 30-35 times of the calcined powder in weight, stirring for 30-60 min, filtering out water and drying; grinding a dried solid by a ball mill, and screening with a sieve of 300-350 meshes to obtain the coffee ceramic pigment. The coffee ceramic pigment is narrow in particle size distribution, stable in color generation, small in chromatic difference change, good in stability at high temperature, meanwhile, simple in manufacturing technology and process, low in equipment requirement and easy for realizing industrial production.

Description

technical field [0001] The invention relates to a ceramic color material, in particular to a brown ceramic color material and a preparation method thereof, belonging to the technical field of ceramic color material preparation. Background technique [0002] Ceramics are various products made of natural clay and various natural minerals as the main raw materials through crushing, kneading, molding and calcination. Painted pottery, also known as ceramic painting, is an art in my country's long-standing "national quintessence" - ceramic art. Painted pottery is beautifully made, mainly clay pottery, the color is painted before firing, and the texture is fine, so it is not only a practical vessel, but also has high artistic value. [0003] Ceramic pigments, also known as pigments or color materials, are powdery decorative materials for colored ceramics formulated with color bases and fluxes or additives. Pigment = color base + flux, the color base is the chromogenic substance a...
