Abstract

The embodiment of the invention relates to a water-based acrylic emulsion, water-based halftone printing ink and a preparation method thereof. The water-based halftone printing ink comprises the following raw material components in parts by weight: 10-35 parts of water-based polyurethane and acrylate copolymer resin, 10-40 parts of water-based acrylic emulsion, 2-8 parts of solid acrylic resin, 5-40 parts of pigment, 0.1-3 part of a dispersing agent, 0.1-2 part of a defoaming agent, 1.7-13 parts of an auxiliary agent and 6-32 parts of water. According to the embodiment of the invention, the red, yellow and blue pigments with pure hue and good transparency and the resin binder with good dot reproducibility are selected, so that the obtained water-based halftone printing ink is good in adhesive force, good in halftone dot reproducibility, high in printing speed and suitable for exquisite halftone dot rapid rotary printing.

Description

technical field [0001] The invention belongs to the technical field of fine chemicals, and relates to a water-based acrylic emulsion, a water-based halftone printing ink and a preparation method thereof. Background technique [0002] At present, the impact of VOC emissions on environmental pollution has attracted social attention and attention. The use of solvents in popular printing inks in the market is not environmentally friendly, causing serious environmental pollution, and may cause solvent residues to pollute packaging, while related water-based inks have half-tone levels. Printing effect is poor. The market urgently needs a water-based halftone printing ink to replace the printing ink that pollutes the environment and emits a lot of VOC. Contents of the invention [0003] In view of this, the embodiment of the present invention provides a water-based acrylic emulsion, a water-based halftone printing ink and a preparation method thereof. The embodiment of the prese...
