Experimental study of water-based emulsion paper-plastic composite adhesive

Emulsion type;  adhesives;  Paper-plastic lamination

The polymerization of vinyl acetate and butyl acrylate as the main monomers by semi-continuous emulsion polymerization was studied. According to the FOX equation, the appropriate proportion of monomer was determined, new crosslinkers A and B were developed, and their addition ratio was determined, and the joint use of A and B greatly improved the adhesion performance. The polymerization conditions were investigated from the influence of polymerization reaction conditions (such as polymerization temperature and drop acceleration of monomers) on the properties of the adhesive, and the reaction process was determined. The results show that under suitable polymerization conditions, acrylate and vinyl acetate are used as the main raw materials, and crosslinkers A and B are added to synthesize a new emulsion-type paper-plastic composite adhesive with no pollution and low cost, and the product performance is excellent.
