Abstract

The invention provides an environment-friendly ink. The environment-friendly ink is prepared from the following components in percentage by weight: 63 to 70 percent of waterborne polyurethane resin; 12 to 15 percent of isopropanol; 5 to 10 percent of water-based pigment; 2 to 4 percent of 2-ethylhexyl acrylate; 4 to 5 percent of epoxy resin; 1 to 3 percent of methylnaphthalene sodium sulfonate. The environment-friendly ink provided by the invention has the characteristics of small influence of environmental temperature and excellent performance. Meanwhile, the invention also provides a preparation method of the environment-friendly ink.

Description

technical field [0001] The invention relates to the technical field of ink, in particular to an environmentally friendly ink and a preparation method thereof. Background technique [0002] Water-based ink is mainly composed of binders, pigments, additives and other components. Because of its low VOC content and low pollution, it is widely used in products with strict packaging requirements such as children's toys, medicines, food, and beverages. In the ink formulation, the selection of binders, additives, and specific parameters in the processing technology have a greater impact on the performance of the ink. [0003] In the related technology, due to the unreasonable ink formula, the ambient temperature has a great influence on the performance of the ink during use. For example, when the ambient temperature is low, it is easy to cause no ink or ink to fall off, thus affecting the quality of the product. quality. [0004] Therefore, it is necessary to provide a new environ...
