Description
Technical Field
The application relates to the field of ink processing, in particular to a preparation method of water-based ink and a printing process thereof.
Background
The use of aqueous inks has many advantages. Firstly, the environment is not polluted, and the personal safety of operators is not influenced. In addition, the phenomenon of residual solvent in the machine does not exist, and the machine is simple and easy to clean. When the product printed by the water-based ink is used for packaging food, no residual solvent is contained, and the food cannot be polluted. In addition, the use of aqueous inks for printing books has become more popular, and research and development of aqueous inks has become a major trend. However, water-based inks have certain disadvantages in terms of gloss, abrasion resistance, ink layer drying speed, pigment dispersibility, and the like, as compared with solvent-based inks.
Although the water-based ink has the advantages of environmental protection, no environmental pollution, no harm to human health and the like, as the water-based ink is a new ink, a plurality of performance researches are not mature, and a plurality of problems still exist in practical application, thereby hindering the development of the water-based ink to a certain extent.
At present, water-based ink binders commonly used for water-based ink mainly comprise two categories of water-based polyacrylic resin emulsion and water-based polyurethane emulsion, and the water-based polyacrylic resin emulsion has the advantages of low price, strong adhesive force, wide applicability of base materials, low viscosity and slow drying speed; the waterborne polyurethane emulsion has the advantages of high viscosity, good glossiness and high surface drying speed, but has weaker tinting strength. Therefore, it is an object of the present invention to improve the coloring power of the aqueous polyacrylic resin ink.
Disclosure of Invention
In order to improve the tinting strength of the water-based ink, the application provides a preparation method of the water-based ink and a printing process thereof.
In a first aspect, the present application provides a water-based ink and a preparation method thereof, which adopts the following technical scheme:
the water-based ink comprises the following raw materials in parts by weight: 11-19 parts of pigment, 5-8 parts of surfactant, 45-68 parts of composite binder, 80-121 parts of deionized water, 15-20 parts of ammonia water, 4-7 parts of thickener, 6-9 parts of polyether modified polysiloxane defoamer, 2-5 parts of ink diluent, 2-8 parts of slow drying agent, 3-5 parts of candle agent polyethylene wax slurry and 2-5 parts of metal ion exchanger sodium metaaluminate; the composite connecting material comprises modified epoxy resin, acrylic resin and organic silicon resin, wherein the mass ratio of the modified epoxy resin to the acrylic resin to the organic silicon resin is (1.2-2.0): (2.3-3.1): (0.8-1.9).
By adopting the technical scheme, the resin for the binder is adopted, so that the main performance of the whole ink is controlled in the development of the water-based ink. The advantages and disadvantages of the connecting materials can directly influence the performances of the ink such as hue, glossiness, adhesion force, drying speed and the like, so the research and development of the connecting materials pay attention to the fact that phthalocyanine pigments have bright colors and strong tinting strength, are superior to iron blue, are stable to light, heat, acid and alkali, influence of colorants on the environmental protection of water-based ink and influence of the colorants on other performances of the ink are very important, and in order to enhance the hydrophilicity of resin and the affinity of the resin and the pigments, some alkaline surfactants must be added to strengthen the adhesion force of the pigments.
The modified epoxy resin, the acrylic resin and the organic silicon resin are mixed in proportion to be used as main resin of the ink binder, sodium metaaluminate serving as a metal ion crosslinking agent is added and mixed with the main resin, and ammonia water is used for providing an alkaline environment to accelerate resin dissolution. In addition, the modified epoxy resin is added to improve the performance of the binder, so that the binder with good viscosity, adhesive force, wear resistance, glossiness and stability is synthesized; modified epoxy resin, acrylic resin and organic silicon resin are used as main components of the water-based screen printing ink. Plays a crucial role in the printing properties (in particular viscosity, stability, flowability and resistance) of aqueous screen-printing inks and is central to aqueous screen-printing inks. The water-based acrylic resin is the pollution-free resin with the fastest growing use speed in the water-based resin. Epoxy resin is one of the most commonly used base resins, and has the advantage of strong adhesion, and hydroxyl groups and epoxy groups in the epoxy resin can react with acrylate, so that the base resin is more stable. The water-based ink prepared by taking the composite binder as the binder has excellent wear resistance, adhesive force, chemical resistance and flexibility and hardness balance.
Deionized water is a main solvent of the water-based ink, but the deionized water cannot well dissolve the resin, and ammonia water needs to be added into the deionized water to promote the dissolution of the resin and ensure the dissolution of the resin, so that the dispersibility of the pigment is improved, and the adhesive force of the water-based ink is improved. The addition of a proper amount of thickener in the water-based paint can improve the performance of the ink and improve the processability, thixotropy, pigment dispersion and storage stability of the ink.
