Abstract

The invention discloses an aluminum foil surface intaglio printing ink. The aluminum foil surface intaglio printing ink is prepared by using 30-35% of polyurethane resin, 10-15% of polyester resin, 8-12% of carbon black, 30-37% of a solvent, 2-3% of an assistant and 10-20% of a filler. The ink provided by the invention has a very good bonding performance with aluminum foil, overcomes the bare phenomenon due to oil stains on the surface of the aluminum foil, and has the characteristics of fast drying speed and good water resistance.

Description

Technical field [0001] The invention relates to the technical field of printing inks, in particular to an ink printed on the surface of an aluminum foil by a gravure coating method. Background technique [0002] In recent years, aluminum foil has been widely used in many fields such as food, medicine, aerospace, etc. due to its light weight, good sealing, good covering, and environmental protection. Since 2006, China's aluminum foil production capacity and output have continued to rank first in the world. The demand for aluminum foil market is growing rapidly. In 2008, China's aluminum foil output was 1.57 million tons, accounting for 44% of the global total. At present, China's annual consumption of aluminum foil has become the world's second largest aluminum foil consumer after the United States. [0003] The food industry and the pharmaceutical industry are important markets for aluminum foil packaging. Their requirements for printing inks are water-based, non-toxic, have go...
