Wine red high-gloss environmental ink and preparation method thereof

Abstract

The invention relates to a wine red high-gloss environmental ink, comprising the following raw materials in parts by weight: 10 parts of silver powder, 60 parts of pigment red 149, 20 parts of pigment red 206, 60 parts of castor oil alkyd resin, 20 parts of melamine formaldehyde resin, 5 parts of triammonium citrate, 5 parts of butyl glycidyl ether, 0.5 part of coconut oil fatty acid diethanolamide, 0.5 part of 2,6-di-tertiary butyl methyl phenol and 80 parts of a mixed solvent. The mixed solvent of dimethyl carbonate and trimethylolpropane is adopted, so that the environmental ink basically does not contain toxic chemical substances such as benzene and toluene is excellent in environmental performance, has excellent dissolving and dispersing performances on resin and pigment, not only gives good durability of the ink, but also displays fairly good printing quality. The environmental ink disclosed by the invention is applicable to silk-screen printing of glass and a polymethyl methacrylate (PMMA) base material surface, and is vivid and bright in color, stable in adhesion property, and good in oil and alcohol resistance after the ink is dried.

Description

technical field [0001] The invention belongs to the technical field of printing inks, and more specifically, the invention relates to a wine red glossy 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 and dries the conju...

AI Technical Summary

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
