Abstract

The invention discloses a water-based laminating adhesive. The water-based laminating adhesive is prepared from the following components in parts by weight: 40-50 parts of butyl acrylate, 2-10 parts of acrylate compounds, 10-15 parts of functional Sexual aids, 0.1-0.3 parts of buffering agent, 2-10 parts of emulsifier, 0.5-4 parts of initiator, 15-30 parts of deionized water, 0.1-1.5 parts of oxidizing agent and 0.1-1.5 parts of reducing agent. The present invention effectively adjusts the content of each raw material component by adding functional additives. At the same time, the emulsion of the present invention belongs to the self-crosslinking type, and its macromolecules are automatically crosslinked during compounding, and the peeling strength is high; the present invention belongs to the water-based adhesive Glue, environment-friendly, solvent-free, non-flammable, non-explosive, safe to use, less glue applied, and low cost of use.

Description

technical field [0001] The invention relates to the field of adhesive manufacturing, in particular to a water-based laminating adhesive. Background technique [0002] Paper-plastic composite is to use adhesives to combine polypropylene or polyester film with paper prints, which combines the advantages of paper and plastic films, so that the surface of the prints is brighter and smoother, the color is more vivid and full of three-dimensionality, and it also plays a role It is widely used in decorative building materials, packaging materials, hardcover books, product advertisements or manuals, etc. With the development of market economy and the improvement of consumption level, film covering is quite extensive. The adhesive used in paper-plastic composite is called paper-plastic composite adhesive, referred to as paper-plastic laminating adhesive. [0003] Paper-plastic laminating adhesives are divided into two types: oil-based laminating adhesives and water-based laminating...
