Water-based gravure surface printing matte ink for plastic film and preparation method thereof

Abstract

The invention discloses water-based gravure surface printing matte ink for a plastic film and a preparation method thereof. The water-based gravure surface printing matte ink comprises the following raw materials by weight (totaling 100%): 10 to 15% of a pigment, 6 to 8% of a matt material, 38 to 42% of a composite connection material, 32.5-27.8% of a solvent and 6-8% of accessories. The water-based gravure surface printing matte ink has the advantages of safety, environmental-friendliness, lower VOC content, good fluidity, high color concentration, good printability, low printed product glossiness, good leveling property, layered hue, good fastness, and no harmful substances after drying. Prints have blocking resistance, migration resistance, rub resistance, and water resistance. The water-based gravure surface printing matte ink is suitable for market requirements.

Description

technical field

[0001] The invention relates to an ink, in particular to a water-based gravure plastic film surface printing matte ink and a preparation method thereof. Background technique

[0002] Environmental protection and the ink industry combine the actual situation of water-based gravure inks, according to the requirements of the "People's Republic of China Environmental Protection Industry Standard HJ / T371-2007", the corresponding environmental protection and related testing standards for gravure water-based inks GB / T4103-2010 " "Water-based gravure plastic film surface printing ink" aims to specify the technical requirements, test methods, etc. of water-based gravure plastic film surface printing ink. The special function water-based gravure plastic film surface printing matte ink has low gloss, and the printed matter has a hazy and mysterious feeling. Large market demand, but also within the standard requirements.
