Embodiment 1

[0019] Preparation of cobalt blue hybrid pigments: Accurately weigh 109 g of attapulgite, 83 g of dicobalt trioxide, and 102 g of alumina and mix evenly. The resulting mixture is placed in a calciner and crystallized at 1000 °C for 2 h to obtain a bright Blue cobalt blue hybrid pigment, the sample number is S0, and the yield is 97.28%.

Embodiment 2

[0021] Preparation of cobalt blue hybrid pigment: Accurately weigh 219.95 g of halloysite, 83 g of dicobalt trioxide, and 204 g of alumina and mix evenly. The resulting mixture is placed in a calciner and crystallized at 1100 °C for 2 h to obtain a bright Blue cobalt blue hybrid pigment, the sample number is S1, and the yield is 98.42%.

Embodiment 3

[0023] Preparation of cobalt blue hybrid pigment: Accurately weigh 218 g of kaolinite, 83.13 g of tricobalt tetroxide, and 51 g of alumina and mix evenly. The resulting mixture is placed in a calciner and crystallized at 1200 °C for 2 h to obtain a bright blue color. Cobalt blue hybrid pigment, the sample number is S2, and the yield is 98.43%.

Abstract

The invention provides a method for preparing a cobalt blue / clay mineral hybrid pigment by a solid phase method, and belongs to the field of nano spinel hybrid pigments. In this method, clay minerals, cobalt sources, and aluminum sources are mixed according to a certain ratio, and the mixture is placed in a calciner and calcined at 1000-1300°C for 1-2 hours to obtain the product. The invention provides a method for preparing a blue cobalt blue hybrid pigment with low cost, high brightness, high yield and simple preparation process. The cobalt blue clay mineral hybrid pigment is prepared by a solid phase method, and the process is simple and the yield is high. , and the introduction of clay minerals can achieve the hue regulation of cobalt blue pigments.

Description

technical field [0001] The invention belongs to the field of nano-spinel hybrid pigments, and relates to a preparation method for cobalt blue / clay mineral hybrid pigments prepared by a solid phase method. Background technique [0002] Cobalt Blue (CoAl 2 o 4 ) as an important spinel inorganic pigment, due to its good heat resistance, acid resistance, alkali resistance and chemical stability, it is mainly used in coatings, ceramics, high temperature resistant coatings and other industries. But the traditional preparation method of cobalt blue pigment is solid-phase method, and the particle size distribution of cobalt blue pigment is inhomogeneous, and calcining temperature is high, and the cobalt blue nano-particle agglomeration of formation is serious, and the raw material Co of preparation cobalt blue pigment is expensive, has certain Environmental toxicity. Therefore, it is particularly important to develop an effective, low-cost, high-chroma cobalt blue pigment prepara...
