Abstract

A self-crosslink acrylic ester compound emulsion for plastic ink and a preparation method thereof belong to the technical field of macromolecular synthesis. In order to solve the problems of the'ink shrinking' of the plastic ink on the surface of plastics and the adhesion force, the invention provides the self-crosslink acrylic ester compound emulsion for the plastic ink. The latex is a product obtained through emulsion polymerization which is carried out by a functional monomer with low polymerization shrinkage, low surface tension and higher permeability and other vinyl monomers. The invention also discloses the preparation method for the emulsion. The preparation method which is carried out through the pre-emulsification nucleocapsid emulsion technology mainly comprises the following two steps: 1. preparing a seed nucleus emulsion; and 2. preparing the nucleocapsid emulsion based on the seed nucleus emulsion to finally obtain the self-crosslink acrylic ester compound emulsion for the plastic ink. The emulsion which is bright and transparent after film forming has good adhesion force to a plastic base material, and the adhesion force to PP, PE films is particularly excellent.

Description

technical field [0001] The invention relates to a self-crosslinking acrylate composition emulsion for plastic ink and a preparation method thereof, belonging to the technical field of polymer synthesis. Background technique [0002] Paper printing has a history of thousands of years in our country, while plastic film printing has only a few decades of history in our country. With the development of the petrochemical industry, the mass production and wide application of polyethylene (PE), polypropylene (PP) and polyvinyl chloride (PVC) have promoted the development of plastic printing and corresponding inks. Paper is a porous substrate, while plastic film is a substrate with a dense and smooth surface, which highlights the different requirements for inks, with adhesion being the most obvious issue. Since the 1980s, the binders for plastic inks have basically been oil-soluble resins. The common ones are chlorinated polypropylene, chlorinated polyethylene, random polypropylen...
