High-adhesion, high-brilliant-silver and environment-friendly printing ink and preparation method thereof

Abstract

The invention relates to high-adhesion, high-brilliant-silver and environment-friendly printing ink which comprises the following components in parts by weight: 75 parts of insulating silver powder, 60 parts of lauryl methacrylate, 18 parts of trimethylolpropane triacrylate, 5 parts of potassium sodium tartrate, 7 parts of butyl glycidyl ether, 0.5 parts of polydimethylsiloxane, 0.5 parts of 2,6-dibutyl cresol and 80 parts of mixed solvent. The environment-friendly printing ink adopts the mixed solvent of dimethyl carbonate and propylene glycol polyether with the molecular weight of 800-2000, is basically free of toxic chemicals such as benzene and methylbenzene, is very excellent in environment-friendly property, and has excellent dissolving and dispersing properties for resin and a pigment; good durability is endowed for the printing ink; very good printing quality is represented; the environment-friendly printing ink is suitable for silk-screen printing of the surfaces of glass, a PMMA (polymethyl methacrylate) substrate and a PC (poly carbonate) substrate; and after the printing ink is dried, the printing ink is bright in color, and excellent in scratch resistance and adhesivity.

Description

technical field [0001] The invention belongs to the technical field of printing ink, and more specifically, the invention relates to a high-adhesion high-brightness silver environmental protection ink and a preparation method thereof. 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...

Problems solved by technology

In order to ensure the printing quality, such as mineral oil, hydrocarbon solvents such as solvents, aromatic solvents such as xylene and ethylbenzene, and ester solvent-based inks such as butyl acetate are usually required in the prior art, but these solvents are highly toxic , have different degrees of pollution and damage to environmental sanitation and personnel health, and there are often residual harmful substances in the dried ink, so it is difficult to meet the requirements of green environmental protection
