Embodiment 1

[0013] 1) First fill the ball mill with high alumina balls, the weight ratio of high alumina balls and materials is 5:1, and then cross feed the materials; the materials are calcined aluminum hydroxide with a weight percentage of 70% and aluminum oxide with a weight percentage of 30%, And sodium fluoride (i.e. mineralizer sodium salt) accounting for 1% of the total weight of calcined aluminum hydroxide and aluminum oxide, the above three raw materials are put into the ball mill crosswise to make these materials mix fully and uniformly; The time is 25 hours;

[0014] 2) Calcining the material obtained in the above step 1) in a kiln at 1050-1100°C for 6 hours;

[0015] 3) Pulverize the material obtained in step 2) to a particle size of less than 50 μm.

[0016] Press the prepared aluminum-iron red into the building ceramic base powder according to the addition amount of 2% (that is, the weight percentage of the aluminum-iron red in the building ceramic base powder), and then fi...

Abstract

The invention discloses a preparation method of an aluminum iron oxide red ceramic pigment. The method comprises the following steps: putting a mixture of 70% to 80% of calcined aluminum hydroxide, 20 to 30% of ferric oxide and a sodium salt as a mineralization agent by weight percent into a ball miller in a crossing manner to carry out a ball-milling treatment for 25 to 40 hours, wherein the adding amount of the sodium salt accounts for 1% to 5% of the total weight of calcined aluminum hydroxide and ferric oxide, and high-aluminum balls are adopted as ball-milling materials; calcining the material mixture in a kiln at the high temperature of 1050 to 1100 DEG C for 6 to 15 hours; and finally crushing the obtained material to reach the granularity of less than 50 mu m. According to the method, the price of the raw materials is low, so that the cost is saved; and on the premise that the calcining temperature for aluminum iron oxide red in the body kiln reaches 1250 DEG C, the produced architectural ceramic is less in color aberration change, good in stability and bright in forming color, thereby commendably satisfying the aesthetic requirements of people in daily life.

Description

technical field [0001] The invention relates to a preparation method of a ceramic color material, in particular to a preparation method of an aluminum-iron red ceramic color material. Background technique [0002] Red has always been a color widely used in people's lives and is loved by people. However, the traditional ceramic pigment zirconium iron red is expensive and causes great pollution to the environment. As a cheap ceramic colorant, iron silicon red has poor stability, and it is easy to form color difference or lighten in high temperature environment. [0003] In recent years, the competition in the architectural ceramics market has become increasingly fierce, and a new type of red ceramic pigment is needed, which needs to meet: 1. Low price, which can save costs for the production of architectural ceramics; 2. Stable color development in high temperature 1200°C environment, and The color is bright, which meets people's daily aesthetic requirements; because in cera...
