Embodiment Construction

[0010] A kind of production method of plastic flexible packaging water-based gravure printing ink, its step comprises following operation:

[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 disperser and heating device, slowly put in alkali-soluble acrylic copolymer resin while dispersing, disperse for 20 minutes, wait for the temperature to rise to 65°C, and then slowly add a Ethanolamine, carry out resin constant temperature amination reaction, amination for two hours, continuously detect the pH value of the aminated resin solution during the amination period, and control the pH value of the resin solution between 9.0-9.5, the resin is diss...

Abstract

The invention relates to a method for plastic soft package water-based intaglio printing ink. The method comprises the following steps: (1) preparing water-based resin liquid; (2) preparing water-based ink color paste; (3) preparing water-based varnish; (4) preparing water-based ink. As the method adopts the amination of modified acrylic polymer water-based acrylic resin SR-630 to prepare the water-based resin liquid; then, the water-based resin liquid is utilized to prepare the water-based ink color paste and the water-based varnish respectively; the plastic soft package water-based intaglio printing ink is prepared through mixing the water-based ink color paste with the water-based varnish according to the required water-based ink. The method has the advantages that the technological requirements are low, the production efficiency is high, and the quality of products is stable; the printing ink produced by the method is the most ideal substitute for solvent-based ink because of the advantages of the ink, such as light smell, good drying balance equality, excellent drying speed, bright color, good glossiness, excellent adhesive force and excellent composite strength.

Description

technical field [0001] The invention relates to a production method of water-based gravure printing ink for plastic flexible packaging. Background technique [0002] Solvent-based ink is a traditional ink, which has the advantages of mature technology and stable quality. However, its volatiles pollute the environment and do serious harm to human health. At present, the development of water-based ink is changing with each passing day, and it can be printed on various substrates including paper, cardboard, cardboard, plastic film, and aluminum foil. However, water-based gravure inks for plastic film printing still have disadvantages such as slow drying speed and poor quality stability. Contents of the invention [0003] The object of the present invention is to provide a method for producing water-based gravure printing ink for plastic flexible packaging with low odor, good drying balance and drying speed, bright color, good gloss, excellent adhesion and composite strength...
