Problems solved by technology

[0003] But in the prior art, the ink used for printing has weak adhesion, the pigment is easy to fall off, and the applicable materials are limited
At the same time, in order to ensure the printing quality, a large amount of highly toxic solvents such as benzenes and ketones are used in its preparation, such as hydrocarbon solvents such as solvents, aromatic solvents such as xylene and ethylbenzene, butyl acetate, etc. Ester solvent-based ink, when the solvent is not handled properly d...

Abstract

The invention relates to the technical field of printing ink and in particular relates to high-adhesive force printing ink. The high-adhesive force printing ink is prepared from the following raw materials in parts by weight: 15-40 parts of a superfine polyimide resin, 2-6 parts of nano silicon dioxide, 3-7 parts of tert-butylhydroquinone, 4-9 parts of methyl cellulose, 12-19 parts of titanium dioxide, 15-25 parts of ethanol and 10-20 parts of pentaerythritol. The printing ink disclosed by the invention has high adhesive force, does not contain any toxic substance, is environment-friendly to a human body and harmless to the environment, has high wear resistance and fire resistance and can emit ultraviolet rays so as to prevent fading.

Description

technical field [0001] The invention relates to the technical field of ink, in particular to a high adhesion ink. Background technique [0002] Ink is an important material for printing packaging materials. It expresses patterns and characters on the substrate through printing. The ink includes main components and auxiliary components. They are evenly mixed and rolled repeatedly to form a viscous colloidal fluid. Printing ink is a paste-like colloid formed by uniformly dispersing and mixing materials such as colorants, linking materials, additives, and solvents. The binder of solvent-based ink is composed of solid resin and a large amount of volatile organic solvent. After the solid resin is dissolved in the solvent, the coloring material is evenly dispersed in the binder, and after the ink is printed on the printing medium, the solvent quickly evaporates and dries the conjunctiva. For inks, it is generally desirable to use print properties that produce both pleasing aesth...
