Example Embodiment

[0025] Example 1

[0026] The bright black environmental protection ink of this embodiment is composed of 65 parts of pearl powder, 20 parts of carbon black, 60 parts of methyl acrylate, 20 parts of 1,4 butanediol diacrylate, and 5 parts of potassium sodium tartrate in parts by weight. , 6 parts of fatty glycidyl ether, 0.4 parts of polydimethylsiloxane, 0.5 parts of 2,6-dibutyl cresol, 60 parts of dimethyl carbonate and 20 parts of polytetrahydrofuran ether diol with a molecular weight of 800-1000. The environmental protection ink is prepared by the following process steps: (1) 60 parts of methyl acrylate, 20 parts of dimethyl carbonate and 10 parts of polytetrahydrofuran ether diol with a molecular weight of 800-1000 are stirred at a low speed (50-100 parts); (2) 20 parts of dimethyl carbonate and 10 parts of polytetrahydrofuran ether glycol with a molecular weight of 800-1000 are stirred at a low speed (50 to 100 r / min) Mix evenly, then add 0.5 parts of 2,6-dibutylcresol a...

Abstract

The invention relates to brilliant black environment-friendly printing ink which comprises the following components in parts by weight: 65 parts of pearl powder, 20 parts of carbon black, 60 parts of methyl acrylate, 20 parts of 1,4-butanediol diacrylate, 5 parts of potassium sodium tartrate, 6 parts of aliphatic polyalcohol glycidyl ether, 0.4 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 polytetrahydrofuran ether glycol with the molecular weight of 800-1000, 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, stable in adhesivity, and good in oil resistance and alcohol resistance.

Description

technical field [0001] The invention belongs to the technical field of printing ink, and more specifically, the invention relates to a bright black 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 conjuncti...
