Description
Technical Field
The invention relates to the field of application of a water-based plastic gravure printing technology, in particular to a water-based plastic inner printing composite gravure printing ink and a preparation method thereof.
Background
With the development of economy and social progress, people have an enhanced awareness of environmental protection, and the industrial production and the application of corresponding products gradually develop towards zero emission and zero pollution. In the packaging and printing industry, people put more strict requirements on packaging materials and printing ink.
The printing ink plays a key role in the packaging and printing process, characters and patterns are vividly and vividly displayed on a printing stock through printing, and the selection of the variety of the printing ink and the quality of the printing effect directly influence the preference of consumers to products. In the increasing awareness of safety and environmental protection of people, the printing ink on the market is subjected to alcohol-soluble and water-soluble printing ink which is gradually popularized from benzene solubility to ester solubility. At present, ester-soluble ink is mainly used as mainstream ink for printing on various substrates, and volatile organic compounds harmful to human and environment are emitted in the production and printing processes of solvent-based ink. Under the current environment protection and the environment with the theme of green production, the solvent-based ink cannot meet the requirements of people for green production and life. In order to solve the problem of influence of solvent-based ink on safety and environment, research technicians begin to search for water-based ink which mainly takes water as a solvent, almost has no emission of volatile organic compounds in the production and printing processes and has good safety. However, since water has a high boiling point, water-based inks using water as a solvent cannot satisfy the requirement of high-speed printing. Meanwhile, the surface tension of water is large, the wettability of the water-based ink to the pigment is poor, the prepared water-based ink is low in color saturation and poor in adhesion fastness, the problems of plate blocking, serious knife thread phenomena and the like exist in the printing process, and the storage stability of the ink is poor. In the invention, the water-based ink prepared by dispersing the pigment through a special process has bright color and high color saturation, and can achieve the effect of deep printing of the traditional solvent-based ink by using shallow printing; and the problem of cutter lines in the printing process and the storage stability are also greatly improved. Therefore, on one hand, the printing speed is greatly improved, on the other hand, the use amount of the printing ink is saved for customers, and the cost is reduced. The resin is self-made with special functional structure by using self-synthesized polyacrylic emulsion and polyurethane emulsionThe emulsion has good Ca resistance2+，Mg2+Therefore, tap water can be directly added in the process of preparing the water-based ink, the redissolution performance of the water-based ink is enhanced, and the problem of plate blockage in the printing process is solved.
At present, compared with the traditional solvent-based ink, the water-based ink has a relatively small market share, and the application market has a large rising space. Compared with the traditional solvent-based ink, the water-based ink also has great advantages in the aspects of safety and environmental protection, but has poorer drying property, adhesion fastness, composite strength, printing performance and the like in individual aspects. The environment-friendly water-based plastic inner printing composite gravure printing ink provided by the invention is improved aiming at the problems of the plastic gravure water-based ink. The water-based ink mainly uses tap water as a solvent, and almost no VOCs is discharged in the preparation and printing processes of the water-based ink. The water-based ink perfects various performance indexes required by the water-based ink by adjusting the formula and improving the ink preparation process.
