Abstract

The invention discloses a water-based laminated adhesive and a production technique thereof. The water-based laminated adhesive mainly comprises deionized water, butyl acrylate, methyl methacrylate, acrylic acid, diisooctyl maleate, diacetone acrylamide, diamidohydrazine adipate, methacrylamido ethyl ethylene urea, an emulsifier, an initiator, a buffering agent, a defoaming agent, a film formation assistant and a preservative. A pre-emulsification technique is utilized to prepare the milk white liquid with blue fluorescence on appearance; the viscosity is 100-500 mPa.s, and the solid content is 48-55%; the film forming material is colorless and transparent, and the pH value is 7-9; the emulsion belongs to a self-crosslinking type; the macromolecules are automatically crosslinked in the compounding process, so the adhesive has high peel strength; and the emulsion has higher solid content, so the adhesive satisfies the requirement of dry-type composite quick drying.

Description

technical field [0001] The invention relates to an adhesive preparation technology, in particular to a water-based film-covering adhesive and a preparation method thereof. Background technique [0002] In the post-press process of the printing and packaging industry, the coating improves the brightness and water resistance of the printed matter, and provides a beautiful visual effect for people's lives. With the continuous emergence of various advanced processes, advanced equipment, and advanced glues, some new trends have emerged in post-press lamination. In recent years, paper-plastic laminating glue has been widely used, mainly in decorative materials, packaging materials, hardcover books and product advertisements. Paper-plastic laminating glue is to use adhesives to laminate polypropylene (BOPP), polyester (PET) and other plastic films with paper prints, thereby greatly improving the appearance and waterproof and anti-fouling properties of prints. Paper-plastic lamina...
