Abstract

The invention relates to a water-based metal ink for UV offset ink and a preparation method thereof. The water-based metal ink comprises the following components by weight: 25-35 parts of water soluble resin, 30-50 parts of a solvent, 1-5 parts of a photoinitiator, 10-30 parts of a metallic pigment, 2-5 parts of a fastness assistant, 2-4 parts of a leveling assistant and 1-3 parts of a wetting and dispersing assistant. Specifically, the solvent is a mixed solvent of deionized water and ethanol in a mass ratio of 1:1, the metallic pigment is bronze powder or aluminum silver powder. The preparation method includes: firstly fully mixing the metallic pigment with the solvent evenly, then adding water soluble resin, the photoinitiator and assistants in order, stirring the materials fully till uniform dispersion, then carrying out filling, sealing and packaging, and performing aluminum foil sealing, thus obtaining the water-based metal ink finished product. Compared with the prior art, the water-based metal ink provided by the invention is green and environment-friendly, has the advantages of good binding fastness with UV offset ink, difficult fall, simple preparation process, good finished product stability, and production cost saving, and is suitable for industrial scale and high efficiency production.

Description

technical field [0001] The invention belongs to the technical field of printing inks, and relates to a water-based metallic ink and a preparation method thereof, in particular to a water-based metallic ink used for UV offset printing inks and a preparation method thereof. Background technique [0002] In tobacco packaging and printing, at present, most domestic manufacturers use solvent-based inks, but with the increasing awareness of environmental protection, the shortcomings of solvent-based inks are becoming more and more prominent. During the printing process, the organic solvent in the solvent-based ink is almost completely dried and evaporated quickly, except for the high concentration of VOC above the printing press, which is treated by catalytic combustion or microbial treatment processes, while others diffuse in the air of the printing workshop Low concentrations of VOC are often directly discharged into the atmosphere. If calculated according to the proportion of ...
