Problems solved by technology

[0002] Nano-carbon black has excellent colorability, weather resistance and chemical stability, and is rich in sources and low in price. It is one of the important colorants. The color effect presented in the ink system is extremely single, and these defects lead to poor stability of the nano-carbon black ink, and the prepared ink has a single appearance and low aesthetics
[0003] At the same time, due to the large specific surface area of ​​nano-carbon black, it is very easy to agglomerate during storage, resulting in an increase in particle volume. In actual use, it takes a long time, high-strength shearing or sanding to disperse, resulting in low production

Description

technical field [0001] The invention relates to the technical field of nano-carbon black modification, more specifically, the invention relates to a nano-carbon black with metallic luster and a preparation method thereof. Background technique [0002] Nano-carbon black has excellent colorability, weather resistance and chemical stability, and is rich in sources and low in price. It is one of the important colorants. The color effect presented in the ink system is extremely single, and these defects lead to poor stability of the nano-carbon black ink, and the prepared ink has a single appearance and low aesthetics. [0003] At the same time, due to the large specific surface area of ​​nano-carbon black, it is very easy to agglomerate during storage, resulting in an increase in particle size. In actual use, it takes a long time, high-strength shearing or sanding to disperse, resulting in low production efficiency and high energy consumption. [0004] In the practical applicat...
