Abstract

The invention relates to a colored laminating adhesive which is prepared from 10-20 wt% of an organic pigment and 80-90 wt% of a laminating adhesive. The organic toner contains 40-45wt% of an organic toner and 55-60wt% of an acrylic acid emulsion. The product itself can be used to synthesize broken color wallpaper without printing. Solid content of the product is high. As the emulsion belongs to a self-crosslinking type, macromolecules of the emulsion crosslink automatically during the composition. Thus, peel strength is high. The product has high quality and excellent comprehensive properties, and can cover powders. After the composition, the product has good brightness, can undergo indentation, embossing, concave-convex formation and the like, has no bubbles, has good toughness, is flat and beautiful, has no glue-opening phenomenon if affected with moisture, is environmentally friendly, is solvent-free, is not inflammable or explosive, and is safe to use. The product provided by the invention has stable comprehensive properties, is convenient to manufacture, popularize and use, and has a wide market prospect.

Description

technical field [0001] The invention relates to a laminating adhesive, in particular to a colored laminating adhesive. Background technique [0002] With the rapid development of printing technology, the application fields of lamination technology are becoming more and more extensive, and its post-press processing technology is also facing more and more technical challenges. Improving the performance and reducing cost of laminating adhesive has become the top priority of many domestic manufacturers. At present, the production technology of laminating adhesive is very mature, and its performance and cost are closely related, so it cannot be at the cost of reducing performance while reducing cost. At present, the lamination of domestic food flexible packaging enterprises is still mainly based on dry lamination. With the rapid development of the economy and the gradual maturity of various conditions, the domestic solvent-free composite and solvent-free polyurethane adhesives ...
