Abstract

The invention specifically relates to a universal binder resin for a water-based plastic surface printing ink, a preparation method thereof and a printing ink using the binder resin, belonging to the field of printing inks. The binder resin provided by the invention is prepared through the following steps: subjecting a modified rosin resin and an amide oligopolymer to a condensation reaction so as to produce an intermediate product with a carboxyl group; allowing the intermediate product and a resin containing multiple carboxyl groups to undergo polymerization; and carrying out amination so as to obtain the water-soluble binder resin. Because of introduction of an acylamino group, the binder resin has good adhesion, luster and printing adaptability on a variety of plastic film substrates. According to the invention, the preparation method for the binder resin is simple; the prepared printing ink has good printing adaptability and is applicable to surface printing of a variety of plastic film substrates, and since water is used as a solvent, the printing ink has no irritant gas and is green and environment-friendly.

Description

technical field [0001] The invention relates to the field of inks, in particular to a general-purpose water-based plastic surface printing ink binder and a preparation method thereof, and to an ink using the binder resin. Background technique [0002] In recent years, with the continuous improvement of people's living standards, the packaging industry has developed rapidly, which has led to the continuous development of plastic gravure ink technology and the market. Its application range includes almost all packaging fields, such as food, medicine, agricultural and sideline products, and daily necessities. Various types of plastic film substrate packaging in other industries. However, the printing inks currently used in the plastic packaging industry are still traditional solvent series, which contain a large amount of toxic and harmful chemical substances, including residual solvents, organic volatiles, and polycyclic aromatic hydrocarbons. Although traditional plastic pri...
