Water-based ink composition, water-based ink resin and preparation method and application thereof

Abstract

The invention relates to the field of water-based ink, and discloses a water-based ink composition, water-based ink resin and a preparation method and application thereof. The water-based ink composition comprises the following components in percent by weight: (1), 20-35wt% of hydroxy-terminated polyamide-ether resin; (2), 5-15wt% of diisocyanate; (3), 2-10wt% of diol; (4), 2-10wt% of diamine sulfonate; (5), 1-6wt% of epoxy alcohol; (6), 45-65wt% of water. The water-based ink resin prepared from the water-based ink composition is good in adhesion and good in printability. After water-based inkprepared from the water-based ink resin is printed onto a packaging substrate, the water-based ink has the advantages of water boiling resistance and steam boiling resistance.

Description

technical field

[0001] The invention relates to the field of water-based ink, in particular to a water-based ink composition, a water-based ink resin and a preparation method and application thereof. Background technique

[0002] High-temperature-resistant steamed food is popular among consumers for its long shelf life, which can be eaten cold or hot, and is easy to carry. This type of food usually needs to undergo high-temperature boiling or steaming after packaging, so higher requirements are placed on food packaging. Not only is the packaging base material required to withstand the test of high temperature, but it is also required that the printed and composited packaging bag has a higher composite strength. With the strengthening of domestic environmental protection awareness, my country's flexible packaging ink products are developing rapidly in the direction of environmental protection and hygiene. Water-based ink is non-toxic, non-irritating, non-corrosive, non-flam...
