Abstract

The invention relates to gloss black printing ink for silk screen printing. The gloss black printing ink comprises the following components in parts by weight: 20 to 25 parts of refined 1000-800 gloss oil, 74 to 76 parts of black pigment, 1.8 to 2.2 parts of transparent red pigment, 13.5 to 14.5 parts of transparent blue pigment, 32 to 40 parts of crylic acid resin, 35 to 42 parts of butyl glycidyl ether, 8 to 10 parts of epoxy soybean oil and 75 to 80 parts of mixed solvent. The printing ink is free from containing phthalate and polyvinyl chloride resin plasticizer; and the mobility of the gloss black printing ink is equivalent to that of the prior art, the storage stability is good, and the film forming performance is good.

Description

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