Waterborne environment-friendly printing ink

Abstract

The invention discloses waterborne environment-friendly printing ink, which belongs to the technical field of printing ink printing. The waterborne environment-friendly printing ink is prepared from the following components in percentage by weight: 13 to 20 percent of waterborne composite resin, 20 to 40 percent of pigments, 0.3 to 3 percent of surfactant, 10 to 18 percent of ethanol, 5 to 15 percent of triethylamine, 1 to 4 percent of additive and 22 to 35 percent of water. The pigment comprises titanium dioxide, and the additive is a defoaming agent and a PH value stabilizer. The water is used for substituting toxic organic solvent in the traditional printing ink, so that the printing ink has no emission of volatile organic solvent (VOC), and is environmentally friendly, and harmless tothe human body, so that the unfavorable influence for the health of the human body and the air pollution of the peripheral environment in the application process can be avoided. In addition, the waterborne environment-friendly printing ink also eliminates the potential hazard of inflammability and explosion, the safety is improved, the environmental protection requirement can be met, and more costcan be reduced compared with the oily printing ink.

Description

technical field [0001] The invention relates to the technical field of inks, in particular to a water-based environmentally friendly ink. Background technique [0002] PM2.5 is a pollutant in the atmosphere. Volatile organic compounds account for 22% of the substances that form PM2.5, and about 20% of the volatile organic compounds are produced by solvent-based coatings and ink emissions. Solvent-based coatings and traditional inks need to be diluted with organic solvents, which not only consume fossil energy, but also contain a large amount of toxic and harmful substances such as benzene, toluene, xylene, etc., and some of them have a volatilization period of more than ten years. In addition, during the printing process, it will have adverse effects on the health of workers and the surrounding environment. There are also flammable and explosive safety hazards in the workplace and storage environment, and the production cost is relatively high. Today, when people pay more a...
