Abstract

The invention relates to an ink for metal packaging containers and a preparation method thereof. The ink contains the following components in parts by mass: 50-60 parts of resin oil, 4-15 parts of melamine formaldehyde resin, 10-20 parts of butyl lactate, 15-25 parts of permanent red, 1-4 parts of Yintiebao red, 2-5 parts of soft phospholipid, 0.5-1.8 parts of organobentonite, 1-3 parts of manganese naphthenate, 0.6-1.6 parts of acetanilide, 0.5-1.5 parts of p-toluenesulfonic acid, 1-3 parts of dimethyl phthalate and 3-7 parts of eugenol. The ink provided by the invention has the advantages of excellent corrosion resistance, excellent erosion resistance and excellent aging resistance; after being applied onto the metal packaging container surface, the ink can not be easily corroded by chemicals and can not be easily aged after long-time insolation in the sun; and thus, the ink has long service life.

Description

technical field [0001] The invention relates to the technical field of packaging materials, in particular to an ink for metal packaging containers and a preparation method thereof. Background technique [0002] Metal packaging containers refer to thin-walled packaging containers made of sheet metal. It is widely used in food packaging, pharmaceutical packaging, daily necessities packaging, instrumentation packaging, industrial product packaging, arms packaging, etc. Among them, the largest number is used for food packaging. [0003] In order to achieve the purpose of identification and aesthetics, ink needs to be painted on the surface of the metal packaging container. At present, the existing inks used on the surface of metal packaging containers have low anti-corrosion and corrosion resistance, and do not have excellent anti-aging effects. The inks are easily corroded and peeled off. After being exposed to sunlight for a long time, the inks are prone to aging and fading....
