Abstract

The invention discloses an adhesion promoter for intaglio ink and a preparation method thereof. The preparation method comprises the following steps: mixing a plant oleic acid with a solvent; adding an amino silane coupling agent; reacting; cooling; and regulating the viscosity of the product with the solvent so as to obtain the adhesion promoter for the intaglio ink. The adhesion promoter for the intaglio ink is prepared by chemical reaction of the silane coupling agent and the plant oleic acid, can be directly added in the intaglio ink without influencing the printability and storage property of the ink, contains no aromatic hydrocarbon solvents and belongs to an environment-friendly auxiliary for the ink; the binding fastness on various base materials, such as neutral paper, polyethylene terephthalate (PET) and the like, is greatly promoted; the volatility and the heavy metal content index of the adhesion promoter meet related technical requirements of environment-friendly products; the production process is simple, the reaction temperature is low, and the production process is easy to control; and the viscosity of the prepared adhesion promoter is moderate, and the property ofthe prepared adhesion promoter is stable.

Description

technical field [0001] The invention relates to an adhesion promoter for ink. Background technique [0002] In the printing industry, especially the engraving gravure inks used for high-end banknote printing, it needs to adapt to both permeable and non-porous printing substrates, so the adhesion performance of gravure printing inks to different printing substrates is particularly important. [0003] Adhesion promoters currently on the market, such as titanate coupling agents, silane coupling agents, aldehyde and ketone adhesion promoter resins, etc. either have unsatisfactory effects in improving the adhesion in engraving gravure inks, or the solvents used are not environmentally friendly. Moreover, the application of these adhesion aids will also affect the ink properties and storage stability of the ink. Contents of the invention [0004] The object of the present invention is to provide an adhesion promoter for engraving gravure ink and a preparation method thereof, so...
