Problems solved by technology

In order to overcome the shortcoming of slow drying speed caused by ink printing, usually only 24-32μm shallow printing can be used, but such shallow printing is prone to printing problems such as dry plate and plate blocking, which will greatly affect the printing quality. Effect
In addition, when using a shallow plate for ink printing, it is also necessary to modify the drying system of the printing machine, which will also lead to a decrease in printing speed; at the same time, changing the printing plate to a lighter plate will shorten the life of the printing plate and increase the printing cost. ;In addition, equipment renewal or transformation will also increase additional costs; these are the main reasons why printing manufacturers do not intend to use ink, and are also key issues that have plagued the ink printing industry for a long time

Abstract

The invention belongs to the technical field of ink, and discloses water-based ink with high drying speed and a preparation method of the water-based ink. The water-based ink comprises the following components: a binder, a pigment, an auxiliary agent and a solvent; and the binder is prepared from tea oil modified waterborne polyurethane, epoxy modified acrylic resin and a butyl acrylate-dibutyl itaconate composite emulsion. The prepared water-based ink is excellent in comprehensive performance, has the outstanding advantage of being high in drying speed while having good adhesive force, dyeing property and stability, and can meet the actual requirements of the ink printing industry.

Description

technical field [0001] The invention belongs to the technical field of inks, in particular to a water-based ink with fast drying speed and a preparation method thereof. Background technique [0002] Water-based ink (water ink) is an environmentally friendly alternative to solvent ink. It uses non-toxic, harmless and safe water to replace the chemical solvents used in traditional inks, and solves the problems of environmental pollution, static electricity, flammability and explosion that have long plagued the printing industry. . [0003] Ink printing is a special printing technology, which can show detailed color changes on the carrier. However, since the drying time of water-based ink is much longer than that of traditional solvent ink, it greatly restricts the promotion and application of ink printing. In order to overcome the shortcoming of slow drying speed caused by ink printing, usually only 24-32μm shallow printing can be used, but such shallow printing is prone to ...
