Problems solved by technology

However, the drying speed of some existing printing inks is too slow, which often causes the backside to be smeared and stuck to the page during printing.
There are also some printing inks with poor adhesion, which are prone to uneven printing and deinking, which seriously affect the printing quality, and the surface tension of the ink is related to the transfer performance of the ink and the stability of the imprint on the printing surface. When the surface of the ink When the tension is g

Abstract

The invention discloses printing ink which comprises the following materials in parts by weight, 20-40 parts of pigments, 20-40 parts of binders, 25-45 parts of solvents, 1-2 parts of calcium carbonate, 1-3 parts of defoaming agents, 1-3 parts of flatting agents, 2-6 parts of 5A molecular sieves, 1-2 parts of fumed silica, 2-6 parts of dispersing agents, 0.5-1.5 parts of adhesion promoters, 2-5 parts of gummy oil, 1-3 parts of slipping agents, 1-4 parts of adhesives and 1-3 parts of hydrotalcite. The adhesion force of the ink can be enhanced, ink penetration and ink permeability of the ink are prevented, and the ink is high in chemical stability, long in storage time and stable in printing performance.

Description

technical field [0001] The invention relates to the technical field of ink, in particular to a printing ink. Background technique [0002] Ink is a substance used to form graphic information in the printing process, which directly determines the tone, color, and clarity of the image on the printed matter, so it plays a huge role in the printing process. However, the drying speed of some existing printing inks is too slow, which often causes phenomena such as back smearing and page sticking during printing. There are also some printing inks with poor adhesion, which are prone to uneven printing and deinking, which seriously affect the printing quality, and the surface tension of the ink is related to the transfer performance of the ink and the stability of the imprint on the printing surface. When the surface of the ink When the tension is greater than the surface tension of the printing surface, the imprint will shrink, and even small fish-eye holes will appear; if the surf...
