Example Embodiment
[0010] A method for producing water-based gravure printing ink for plastic flexible packaging, the steps include the following processes:
[0011] (1) Preparation of water-based resin liquid: formula (wt%, the same below):
[0012] Water-based acrylic resin SR-630 35-38;
[0013] Deionized water 48-52;
[0014] Ethanol 4;
[0015] Monoethanolamine 8-12;
[0016] Defoamer 1;
[0017] Total: 100.
[0018] Preparation method: first put deionized water and ethanol solvent into the reaction kettle in proportion, turn on the dispersing machine and heating device, slowly put in alkali-soluble acrylic copolymer resin while dispersing, disperse for 20 minutes and slowly add one drop after the temperature rises to 65°C Ethanolamine, conduct resin constant temperature amination reaction, amination for two hours, continuously check the pH value of the aminated resin solution during amination, and control the pH value of the resin solution between 9.0-9.5, and the resin is safe to dissolve and pH Aft...
