Abstract

The invention relates to a water-based printing ink emulsion for a plastic foil. The emulsion is prepared by the reaction among butyl methacrylate, ethyl acrylate, methyl methacrylate, diacetone-acryloamide, sodium hyposulfite, alcohol ether sodium succinate, a buffering agent, a functional auxiliary agent, ammoniacal liquor and softened water. A preparation method in the invention is also disclosed. According to the invention, the water-based printing ink emulsion enables a large bonding intensity for the plastic foil, and has the advantages of good levelability, aging resistance, no poison, no smell, safety and reliability.

Description

technical field [0001] The invention relates to a water-based ink emulsion used for plastic films and a preparation method thereof. Background technique [0002] Water-based ink emulsion for plastic film is used to prepare water-based ink. It acts as a binder in the ink, bonding the pigments in the ink to each other as a whole, and tightly bonding with the plastic film. [0003] In the past, inks were mostly oily systems, which were easy to bond with plastic films, but a large amount of solvent volatilized, on the one hand, it caused great environmental pollution and harm to the health of operators, and on the other hand, it was very easy to cause fire. With the improvement of human health awareness. Water-based systems are getting more and more attention, but water is a polar material, and it is difficult to bond with non-polar plastic films. Therefore, the adhesion between water-based ink emulsions and plastic films is the key to the use of water-based inks. [0004] At ...
