Abstract

The invention relates to water-based ink and a preparation method thereof, in particular to PE and OPP gravure inner printing compound water-based ink and a preparation method thereof. The water-basedink is prepared from the following raw materials: functional resin, pigments, filler, functional auxiliary agents, a cosolvent and water. The invention also provides a preparation method of the water-based ink. The preparation method comprises the following steps: S1, mixing and stirring 2 / 3 part of functional resin, a dispersant, a wetting agent, a flatting agent, a defoaming agent, a defoamer,the pigments, the filler and water uniformly to obtain a first product; S2, grinding the first product to obtain a second product; and S3, adding the residual 1 / 3 part of functional resin and the cosolvent to be mixed and stirred uniformly and adding a stabilizer to obtain a product. The water-based ink has excellent leveling property, high speed printability, lattice point reproducibility and shallow plate printability, is high in PE and OPP adhesive fastness, clear in multi-chromatographic layer, safe and environment-friendly and has a great application prospect in the field of PE and OPP gravure printing.

Description

technical field [0001] The invention belongs to the technical field of water-based inks, and in particular relates to a composite water-based ink for PE and OPP gravure back printing and a preparation method thereof. Background technique [0002] OPP film (stretched polypropylene film) is a film made of polypropylene as the main raw material and stretched by flat film method. It is colorless, odorless, tasteless and non-toxic. It has high tensile strength, High rigidity, good transparency, good gloss, low static performance, excellent printing performance and coating adhesion, excellent water vapor barrier performance, widely used in various packaging industries. PE film (polyethylene film) has excellent moisture resistance and low moisture permeability. According to different manufacturing methods and control methods, products with different properties such as low-density, medium-density, high-density polyethylene and cross-linked polyethylene can be produced. , Widely use...
