Technical Field

The invention relates to ink, in particular to water-based black ink.

Background

Ink is an important material for printing, and is used for expressing patterns and characters on a printing material through printing or inkjet. The ink comprises a main component and an auxiliary component which are uniformly mixed and repeatedly rolled to form a viscous colloidal fluid. Consists of a binder, a pigment, a filler, an auxiliary agent, a solvent and the like. The printing ink is used for various printing of books, periodicals, packaging decoration, building decoration, electronic circuit boards and the like. As social demands increase, ink varieties and yields also expand and grow accordingly.

The black ink on the market at present belongs to a solvent type, and has the following defects: the solvent type ink has high smell and great environmental pollution; hot summer days are very dangerous for solvent-based inks; the harm to the body of field operators is large.
