Introduction of water-based glue for paper plastic

The water-based glue of the paper-plastic composite adhesive uses water as the medium, is non-toxic and non-flammable; it has good tolerance to other substances and can be modified by various types of additives; the process is simple and easy to use. There are many researches on water-based acrylic adhesives, and many reports have been made. Adding a modifier to acrylate gives a paper-plastic composite film adhesive with strong bonding strength and good toughness.

Using butyl acrylate as the soft monomer, vinyl acetate as the hard monomer and adding a small amount of monomers for modification, the obtained composite film adhesive has high brightness, high bonding strength, no foaming, and no yellowing, which is very suitable for paper Plastic composite adhesive.

Using acrylate as the main raw material, butyl acrylate vinyl acetate acrylic copolymer emulsion was synthesized by semi-continuous emulsion polymerization, and a certain proportion of emulsified rosin tackifying resin was added to it to make a new type of paper-plastic composite adhesive; The adhesive has greatly improved adhesion, stability, and water resistance.

Paper-plastic composite adhesives have synthesized an acrylic emulsion laminating adhesive, in which acrylic acid and acrylonitrile are used as functional monomers, which significantly improves the bonding strength of the laminating adhesive to BOPP biaxially oriented polypropylene and paper.
