Problems solved by technology

In China, rosin-modified maleic acid resin is often used as a binder to make ink, but this ink can only be used for printing general cartons, and cannot meet the gloss and water resistance required by medium and high-end packaging printing; urethane resin It has good stability, but the printing adaptability is slightly worse; later, styrene-modified maleic acid resin, water-based amino resin, water-based alkyd resin, polyvinyl alcohol and carboxymethyl cellulose were developed. Resins generally contain hydrophilic groups such as carboxyl groups, hydroxyl groups, and amino groups. After specific processing, they become completely water-soluble resins and can be used as binders for water-based inks; however, due to the strong hydrophilic groups, if Without further treatment such as crosslinking, the water resistance of the ink after printing is not good

Abstract

The invention provides a preparation method of resin for aqueous ink. The preparation method comprises the following steps that methyl methacrylate, butyl acrylate, acrylic acid, hydroxyethyl methacrylate, glycidyl methacrylate and styrene are dispersed in a certain proportion in a solvent in the presence of an initiator and stirring; after the system is uniform and stable, the reaction is began at a particular temperature; after the reaction is completed, white emulsion resin is obtained. The resin for the aqueous ink and the aqueous ink products prepared from the aqueous ink can improve and increase the water resistance and glossiness of ordinary aqueous inks. Meanwhile, the value obtained by the preparation method and the aqueous ink prepared by the resin, pigments, dispersants, pH adjusting agents and optional others additives are provided.

Description

technical field [0001] The invention relates to the field of ink, in particular to a resin manufacturing method, the resin and water-based ink using the resin. Background technique [0002] Water-based ink has the characteristics of non-toxic, environmental protection, and health. In recent years, the scope of application has been expanding. In terms of decoration of some furniture, office spaces, and children's toys, it is favored by users due to zero VOC emissions. Currently, the market occupies The amount is getting bigger and bigger. [0003] In water-based ink, water-based polymer resin is the most important component of water-based ink. It acts as a binder in water-based ink and has a great influence on the viscosity, adhesion, gloss, drying and printing adaptability of the ink. influences. In China, rosin-modified maleic acid resin is often used as a binder to make ink, but this ink can only be used for printing general cartons, and cannot meet the gloss and water r...
