Abstract

The invention relates to the technical field of printing ink, particularly discloses alcohol-soluble polyamide gravure plastic surface printing ink. The alcohol-soluble polyamide gravure plastic surface printing ink is prepared by mixing the following component by weight: 15-25% of an alcohol-soluble polyamide resin solution, 6-15% of an alcohol-soluble rosin-modified maleic acid resin solution, 2-4% of an alcohol-soluble polyketone resin solution, 5-10% of an alcohol ester-soluble nitro-cotton resin solution, 0.5-1% of wax powder, 9-30% of pigment, 30-40% of anhydrous ethanol, and 0.5-1% of an anti-settling agent. The surface printing ink disclosed by the invention adopts the alcohol-soluble polyamide resin as the main resin, and the alcohol-soluble rosin-modified maleic acid resin and the alcohol-soluble polyketone resin as the auxiliary resins, these three resins all adopt ethanol as a solvent for dissolution, and when the alcohol-soluble polyamide gravure plastic surface printing ink is prepared, ethanol is also used as a solvent system, so that benzene solvent is basically eliminated, and the problems that the benzene solvent system surface printing ink in the prior rat pollutes the environment and is harmful for human bodies and the like are solved.

Description

technical field [0001] The invention relates to the technical field of printing inks, in particular to an alcohol-soluble polyamide gravure plastic surface printing ink. Background technique [0002] Benzene-soluble polyamide plastic surface printing ink has a history of more than 40 years at home and abroad. It is a gravure plastic surface printing ink produced with benzene-soluble polyamide as resin. Benzene-soluble polyamide plastic surface printing ink is mainly suitable for plastic films such as polyethylene and polypropylene, and is used in food, pharmaceutical packaging and other fields. According to relevant data, due to the pollution of benzene-soluble polyamide plastic surface printing inks, the developed countries in the world have stopped the use of benzene-soluble polyamide plastic surface printing inks and started to use water-based inks for surface printing. However, in our country, benzene-containing surface printing plastic inks are still used. Not only doe...
