Description

technical field

[0001] The invention relates to an ultra-fine water-based carbon black slurry for water-based ink or paint, which is especially suitable for coloring and preparing water-based pen inks such as pigment-type black neutral inks, and belongs to the field of processing and application of pigments in fine chemicals. Background technique

[0002] Generally speaking, the color paste mainly plays a role in coloring or fiber dyeing in the manufacturing process of paints and inks. Ink belongs to the category of coating science. Its general manufacturing process is similar to that of paint manufacturing. First, the base color pigment is formulated into a uniform, stable, and high-concentration color paste, and then solvents and other auxiliary agents are formulated into ink.

[0003] Selecting a suitable and stable color paste is an important condition to improve the stability of the finished ink and improve the quality of the product. Due to the special structure of pi...
