A kind of printing ink and its printing process using the ink

Abstract

The invention discloses ink and a printing process using ink. The ink comprises, by weight, 30-50 parts of water-based color paste, 20-30 parts of vegetable oil, 5-10 parts of powder filler, 0.2-2.4 parts of antiwear agent, 2-8 parts of dispersant, 0.5-2 parts of microbial enzyme. The ink is printed on printed materials by the printing process. The ink is environment friendly and easily degradable by microbial enzyme, and therefore has no pollution to the environment.

Description

technical field [0001] The invention relates to the field of printing, in particular to an ink and a printing process using the ink. Background technique [0002] Since the 20th century, the ink printing industry has developed in my country one after another. So far, ink production technology and ink printing technology have led the development of major industries such as education, media and clothing. Gradually, my country has surpassed Asian countries and even Western countries and has become It is the second largest ink consumer after the United States. [0003] The raw materials for preparing ink in traditional technology contain a large amount of mineral oil. During the printing process of substrates or waste incineration, the mineral oil in ink will be decomposed into a large amount of greenhouse gases and fixed pollutants such as carbon dioxide. Objects such as cardboard and wood are covered with insoluble oily chemicals on their surface, so they are discarded in the ...

Problems solved by technology

[0003] The raw materials for preparing ink in traditional technology contain a large amount of mineral oil. During the printing process of substrates or waste incineration, the mineral oil in the ink will be decomposed into a large amount of greenhouse gases and fixed pollutants such as carbon dioxide. Objects such as cardboard and wood are covered with insoluble oily chemicals on the surface, which are difficult to rot when discarded in the soil. Both of them will pollute the environment and increase the pressure of environmental purification, especially if the ink flows into the soil or is printed with traditional ink. The printed substrates flow into the environment, and its harmful components with irritating odor will be used as a soil pollutant, increasing the burden of soil purification

Therefore, traditional inks are not conducive to ecological development
