Abstract

The invention belongs to the technical field of preparation of printing Chinese ink, and particularly relates to environment-friendly printing Chinese ink, which comprises the following components in percentage by weight: 15 to 20 percent of a waterborne polyurethane resin, 50 to 60 percent of a modified waterborne polyurethane resin, 1 to 2 percent of a wetting agent, 2 to 4 percent of an antifoaming agent, 1 to 2 percent of a thickening agent, 1 to 2 percent of a flatting agent and 15 to 20 percent of soft water. The printing Chinese ink is high in dry and wet rubbing fastness, water and chemical resistance, freezing resistance, adhesion, yellowing resistance and weather resistance, a formed film is transparent and high in brightness and fullness, and printed images and texts are full and high in clarity.

Description

technical field [0001] The invention belongs to the technical field of gravure printing ink preparation, and in particular relates to an environmentally friendly printing ink. Background technique [0002] At present, solvent-based gravure printing technology is mostly used in the printing industry of PVC decorative materials, and solvent-based ink is the mainstay of this technology. Although solvent-based inks show enough exquisite printing performance in the printing of decorative materials, a large amount of solvent needs to be added during use, and its volatile organic compounds (VOC) have adverse effects on human health and pollute the environment. According to the Environmental Protection Agency, indoor air pollution can be up to 10 times more polluted than outdoor air if there is not enough ventilation to move the air around and VOCs are present indoors. When the VOC in the living room reaches a certain concentration, people will feel headache, nausea, vomiting, fati...
