Embodiment 1

[0016] An environmentally friendly water-based paper ink is composed of the following components in parts by mass: 30 parts of polyamide resin, 12 parts of nitrocellulose resin, 1.5 parts of acrylic emulsion, 12 parts of pigment filter cake, 1.2 parts of surfactant, organic silicon 0.8 parts of defoamer, 1.5 parts of silicon dioxide, 0.5 parts of stabilizer, 0.5 parts of adhesion promoter, 1.0 parts of wax powder and 30 parts of deionized water.

[0017] The ink of above-mentioned composition is prepared by following steps:

[0018] (1) Weigh the materials, weigh the raw materials in the above mass parts, and set aside;

[0019] (2) Configure the resin liquid, stir and mix the whole weight of the polyurethane resin and the whole weight of the nitrocellulose resin with half the weight of deionized water to obtain the resin liquid;

[0020] (3) Pre-dispersion, take one-third of the weight of the resin solution prepared in step 2), add it to the mixer, add the whole weight of th...

Embodiment 2

[0024] An environmentally friendly water-based paper ink is composed of the following components by mass: 35 parts of polyamide resin, 10 parts of nitrocellulose resin, 1.8 parts of acrylic emulsion, 15 parts of pigment filter cake, 1.5 parts of surfactant, organic silicon 0.8 parts of defoamer, 1.6 parts of silicon dioxide, 0.8 parts of stabilizer, 0.8 parts of adhesion promoter, 1.5 parts of wax powder and 25 parts of deionized water.

[0025] Ink in the present embodiment, its preparation method is the same as embodiment 1.

Abstract

The invention discloses a preparation method of environmental-friendly water-based paper ink. The preparation method comprises the following several steps of weighting materials, and weighing the following raw materials in parts by weight for later use: 25-35 parts of polyamide resin, 10-15 parts of nitrocellulose resin, 1-3 parts of acrylic emulsions, 10-15 parts of pigment filter cakes, 1-2 parts of surface active agents, 0.5-1 part of organic silicon defoaming agents, 1-3 parts of silicon dioxide, 0.5-0.8 part of stabilizing agents, 0.5-0.8 part of adhesive force accelerating agents, 1-3 parts of wax powder and 20-35 parts of deionized water; then preparing a resin solution; then pre-dispersing and dispersing; finally filtering and packaging to obtain finished ink. The preparation method disclosed by the invention has the advantages of simple equipment, good process controllability and the like.

Description

technical field [0001] The invention relates to the technical field of ink preparation, in particular to a method for preparing environmentally friendly water-based paper ink. Background technique [0002] With the development of social culture, science and technology, and economy, the printing industry is developing at an unprecedented speed, and ink is the biggest source of pollution in the printing industry. Ink is an important material used for printing packaging materials. It expresses patterns and characters on the substrate through printing. The ink includes main components and auxiliary components, which are uniformly mixed and rolled repeatedly to form a viscous colloidal fluid. It consists of pigments, binders, additives and solvents. It is used for various printing of books, periodicals, packaging and decoration, architectural decoration, etc. With the increase of social demand, the variety and output of ink have also expanded and increased accordingly. Howeve...
