Problems solved by technology

[0003] In recent years, with the deepening of the country's low-carbon and environmental protection requirements for the printing industry, the demand for low-carbon and environmentally friendly water-based metal inks is becoming more and more urgent. The low-carbon competition in the ink market is becoming increasingly fierce, and the voice of environmental protection and low-carbon is getting louder and louder. , traditional solvent-based (benzene or lipid) inks can no longer adapt to and meet the development needs of the modern printing industry, and water-based metal inks that are environmentally friendly, low-carbon, non-toxic and pollution-free, and meet the needs of national environmental protection development are urgently needed to be launched

Abstract

The invention relates to the technical field of printing ink, and particularly relates to environment-friendly water-based metal printing ink and a preparation method thereof. The environment-friendly water-based metal printing ink comprises 40-60 parts of water-based ink binder, 5-10 parts of dispersing agent, 0.1-1.5 parts of defoaming agent, 5-20 parts of metallic pigment, 0.5-5 parts of surface active agent, 1-5 parts of adhesion promoter and 5-20 parts of solvent. The environment-friendly water-based metal printing ink does not contain volatile poisonous solvents, has a good printing effect on plastic films, no damage to the health of printers and no pollution to atmospheric environments and is relatively low in cost and relatively good in product quality. The preparation method is high in production efficiency and used for producing the environment-friendly water-based metal printing ink on a large scale.

Description

technical field [0001] The invention relates to the technical field of inks, in particular to an environment-friendly water-based metal ink and a preparation method thereof. Background technique [0002] Metallic ink refers to the ink prepared with metallic pigments, which has a metallic luster. Generally speaking, gold ink and silver ink are such inks. The pigments of metal inks are mainly gold powder and silver powder (copper powder and aluminum powder), and other pigments can also be added to produce inks with special colors, which are called colored metal inks. Copper powder is easy to turn black when it reacts with a small amount of sulfur in the linking material when it is acidic; after printing, it will gradually lose its luster when it interacts with sulfur in the atmosphere. Therefore, gold ink can also be made of aluminum powder plus dyes, but The gloss is slightly less. [0003] In recent years, with the deepening of the country's low-carbon and environmental ...
