With the advantages of no pollution and no poison, the water-based ink, as a new type of green packaging material, is especially applicable to the food, medicine and drink packaging. However, the traditional domestic water-based ink, featuring some disadvantages in the properties of stability, gloss and so on, increasingly evolves into an enormous obstacle to the widespread application of the packaging and the rapid development of the whole industry. In this paper, the polyurethane resin is adopted to replace the ordinary binder resin in the experiment of the water-based ink, and the gloss of the polyurethane water-based ink is also studied. It is shown that the gloss of water-based ink is influenced by the dispersion of pigment, water content and surface tension of water-based ink system, hydrotropic agent and some other factors. |
