Abstract

The invention discloses an aqueous dry lamination adhesive and a preparation method thereof. Raw materials of the aqueous dry lamination adhesive comprise styrene, butyl acrylate, isooctyl acrylate, acrylonitrile, N-methylolacrylamide, hydroxyethyl acrylate, acrylic acid, rosin, potassium persulfate, sodium dodecylbenzene sulfonate, isooctyl phenol polyoxyethylene ether, sodium bicarbonate, deionized water, ammonia water, a wetting agent and antifoaming agent. Aqueous latex with a core-shell structure is prepared through a segmented polymerization technology, so functional groups make a substrate and a plastic film be fully bonded, and polymer molecular chains are self-crosslinked, thereby the adhesion and the peeling strength of the substrate are improved, the adhesive has excellent initial adhesion, pressure sensitivity and covering ability, the excellent leveling property and the dynamic wetability of the adhesive make a laminated product have brilliant gloss, and the adhesive can be widely used in paper plastic lamination.

Description

technical field [0001] The invention relates to a packaging printing material, in particular to a water-based dry film-coating glue and a preparation method thereof. Background technique [0002] Dry laminating adhesive is a layer of adhesive that is coated on the plastic film during the paper-plastic laminating process, and then passes through the drying tunnel of the laminating machine to remove the solvent or water in the adhesive, and then Bonded with paper-plastic printed matter under hot pressing to achieve beautiful, bright, waterproof, anti-fouling, increase the mechanical strength of the paper product, abrasion resistance, folding resistance, chemical corrosion resistance and other protective effects. Existing composite film materials are divided into two types: glossy film and matte film. Glossy film requires smoothness and brightness, excellent adhesion, no blistering and no delamination, and matte film requires strong powder covering ability. At present, convent...
