Abstract

The invention belongs to the field of ink, especially relates to an environmental-protection offset printing ink and a preparation process thereof, and is characterized in that the offset printing ink includes the components in parts by mass: 5-10 parts of ink oil, 50-70 parts of gummy oil, 5-10 parts of a filler, 15-20 parts of a pigment, 0.5-5 parts of a drying agent, and 1-5 parts of an auxiliary agent; the ink oil, the gummy oil, the filler, the pigment, the drying agent and the auxiliary agent are added into a material tank according to the formula amount and are stirred, after stirring is qualified, the mixture is ground, after the fineness is qualified, the index is adjusted to be qualified, and then packaging is performed. The raw materials almost harmless to human bodies are adopted, components harmful to the environment and the human bodies in the processes of production and use of the ink are reduced, almost no pollution is produced, the VOC content is extremely low, and the environmental-protection performance is quite good.

Description

technical field [0001] The invention belongs to the field of ink, and in particular relates to an environmentally friendly offset printing ink and a preparation process thereof. Background technique [0002] With the establishment and improvement of environmental protection laws and regulations, China's printing industry as a whole is developing towards environmentally friendly products, and the market's demand for environmentally friendly and sustainable inks will increase day by day. As innovative products with both environmental and economic benefits emerge in an endless stream, the market for solvent-based and petroleum-based inks is gradually being replaced by newly developed environmentally-friendly products. With the advancement of science and technology and the development of the market, my country's ink manufacturing industry has made great progress in recent years, and the market demand has also increased year by year. However, compared with developed countries, t...
