Abstract

The invention provides aqueous degradable environment-friendly ink for printing, a special decoloring agent and a preparation method of the ink. The degradable environment-friendly ink contains dye, wherein the dye is azo-dye or triphenylmethane dye, or macromolecular dye synthesized by one of azo-dye or triphenylmethane dye, and aqueous macromolecular material. The preparation method of the degradable environment-friendly ink comprises the steps of dispersing, grinding and filtering aqueous acrylic resin, dye, de-ionized water, an antifoaming agent, a flatting agent, surfactant and amine materials in a high-speed disperser and a sand mill in sequence. The special decoloring agent is sodium dithionite or 2Na2CO3.3H2O2. The ink has the advantages of environment friendliness, no harmfulness, good safety, stable performance and good printing effect. When waste papers is recycled, the ink can be decoloured quickly under the action of the matching decoloring agent, and therefore, the problems that organic solvent in the oily ink volatilizes, the waste paper is difficult to deink and sewage pollution is serious are solved.

Description

technical field [0001] The invention relates to the field of printing ink and waste paper deinking, in particular to a water-based degradable environment-friendly ink and a decolorizing agent thereof. Background technique [0002] With the development of social culture, science and technology, and economy, the printing industry is developing at an unprecedented speed, and ink is the biggest source of pollution in the printing industry. Traditional oil-based inks use organic solvents such as aromatic hydrocarbons, esters, and ketones as solvents. The content of organic solvents in inks is generally 50%-70%. Most of these solvents will volatilize during the printing process, which seriously pollutes the environment and directly harms human health. The solvent used in water-based ink is mainly deionized water, which can greatly reduce the emission of volatile organic solvents (VOC) and reduce air pollution. Therefore, the research and development of water-based ink is becoming...
