Embodiment 1

[0021] 1) Take CuO 5%, Cr 2 o 3 10%, Al 2 o 3 20%, SiO 2 5%, Fe 2 o 3 20%, ZnO 40%, using a stirring ball mill to refine the raw materials to sub-micron level, mix evenly, and burn at 1100°C for 4 hours to obtain crude pigments;

[0022] 2) Use a stirring ball mill to carry out ultra-fine processing on the crude pigment, until the powder is sub-micron;

[0023] 3) Use grading equipment to process ultra-fine powder and control its D 90 ≤1 靘, separate the ultra-fine powder to obtain the finished product.

Embodiment 2

[0025] 1) Take Cr 2 o 3 20%, Al 2 o 3 20%, Fe 2 o 3 40%, ZnO 20%, using a planetary mill to refine the raw materials to sub-micron level, mix them evenly, and burn them at 1300°C for 2.5 hours to get crude pigments;

[0026] 2) Use a planetary mill to carry out ultra-fine processing on the crude pigment, until the powder is sub-micron;

[0027] 3) Use grading equipment to process ultra-fine powder and control its D 90 ≤1 靘, separate the ultra-fine powder to obtain the finished product.

Embodiment 3

[0029] 1) Take CuO 10%, Cr 2 o 3 10%, Al 2 o 3 30%, SiO 2 5%, Fe 2 o 3 20%, ZnO 25%, use a stirring ball mill to refine the raw materials to sub-micron level, mix evenly, and burn at 1200°C for 3 hours to obtain crude pigments;

[0030] 2) Use a stirring ball mill to carry out ultra-fine processing on the crude pigment, until the powder is sub-micron;

[0031] 3) Use grading equipment to process ultra-fine powder and control its D 90 ≤1 靘, separate the ultra-fine powder to obtain the finished product.

Abstract

The invention discloses a brown pigment for ceramic ink jet printing and a preparation method thereof. The brown ceramic pigment comprises the following materials: 0-10% of CuO, 10-30% of Cr2O3, 20-40% of Al2O3, 0-10 of SiO2, 20-40% of Fe2O3 and 20-40% of ZnO. The method comprises the following steps of: refining the materials and evenly mixing, and sintering at 1100-1300 DEG C to obtain a crude pigment product; super-refining the crude pigment product by using super-fining equipment; and using a grinding machine to treat the super-refined powder to control D90 to be not more than 1 Qing, and separating the super-refined powder to obtain a finished product. Products prepared by the method have the advantages of more uniform chroma and high suspensibility and tinctorial strength, meet the requirements of ink jet printing ink, and have high temperature stability under an antique imitation tile or a transparency glaze and brilliant color tone under the sintered antique imitation tile or transparency glaze, thereby achieving good decoration effect.

Description

technical field [0001] The invention relates to a ceramic pigment and a preparation method thereof, in particular to a brown pigment for ceramic inkjet printing and a preparation method thereof. Background technique [0002] In the past two decades, my country's architectural sanitary ceramics have developed rapidly and have become the world's largest producer of architectural sanitary ceramics. [0003] At present, my country's architectural sanitary ceramic products have got rid of the situation of single variety, monotonous design and color, and incomplete specifications, and formed a relatively complete product system. However, compared with Italy, Spain and other ceramic production powerhouses, there is still a large gap in product grade and competitiveness, and the proportion of middle and low-end products is too high. At the same time, the rapid development of China's economy has continuously improved people's living standards, and people's requirements for decorativ...
