Embodiment 1

[0050] (1) 15kg hydroxyl-terminated polyamide-polyoxyethylene glycol resin (hydroxyl value 32mg (KOH) / g), 6kg hydroxyl-terminated polyamide-tetrahydrofuran-propylene oxide copolymerized glycol resin (hydroxyl value 36mg (KOH) / g) and 13kg of toluene diisocyanate were added to Reactor I, heated to 80°C for 2 hours, and then 7kg of 2,2-dimethyl-1,3-propanediol was added to react for 1.2 hours. The viscosity of the reactant, add 10kg of 2-(2-amino-cyclohexylamino)-sodium ethanesulfonate, stir at room temperature for 0.6 hours, heat up to 60°C, add 4kg of glycidyl alcohol and react for 1.8 hours to obtain a polymer .

[0051] (2) Add 45 kg of water to the reaction kettle II, pour the polymer in the reaction kettle I into the reaction kettle II under stirring, continue to stir and disperse at room temperature for 0.5 hours, remove acetone by vacuuming, and obtain the water-based ink resin.

Embodiment 2

[0053] (1) 27.5kg hydroxyl-terminated polyamide-polyoxypropylene diol resin (hydroxyl value 40mg (KOH) / g), 4kg diphenylmethane diisocyanate and 6kg dicyclohexylmethane diisocyanate are added in the reactor I, After heating to 90°C and reacting for 1.4 hours, add 2kg of 2-ethyl-2-butyl-1,3-propanediol to react for 1 hour, cool down to room temperature and add an appropriate amount of acetone to reduce the viscosity of the reactant, add 7kg of 2-[ (5-amino-1,3,3-trimethyl-cyclohexylmethyl)-amino]-sodium ethanesulfonate, stirred at room temperature for 0.75 hours, raised the temperature to 65°C, added 3.5kg epoxybutanol and reacted for 1.4 hours Polymers are then produced.

[0054] (2) Add 50 kg of water to the reaction kettle II, pour the polymer in the reaction kettle I into the reaction kettle II under stirring, continue to stir and disperse at room temperature for 0.6 hours, and remove acetone by vacuuming to obtain a water-based ink resin.

Embodiment 3

[0056] (1) Add 35kg of hydroxyl-terminated polyamide-polytetrahydrofuran diol resin (hydroxyl value 28mg (KOH) / g) and 5.5kg of hexamethylene diisocyanate into reactor I, heat to 100°C, and react for 1.8 hours , add 2kg of neopentyl glycol, 4kg of 2,4-dimethyl-1,5-pentanediol to react for 1.4 hours, drop to room temperature and add an appropriate amount of acetone to reduce the viscosity of the reactant, add 2kg of 2-[4-( 4-amino-cyclohexylmethyl)-cyclohexylamino]-sodium ethanesulfonate, stirred at room temperature for 1 hour, raised the temperature to 70°C, added 6 kg of glycidyl alcohol and reacted for 2 hours to obtain a polymer.

[0057] (2) Add 45.5kg of water to the reaction kettle II, pour the polymer in the reaction kettle I into the reaction kettle II under stirring, continue to stir and disperse for 0.75 hours at room temperature, and remove the acetone by vacuuming to obtain a water-based ink resin .

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...
