Problems solved by technology

[0003] However, the difficulties of soft packaging companies are that the lamination industry currently lacks water-based lamination adhesives with reliable performance to replace traditional solvent-based lamination adhesives. Solvent-free lamination is also in the exploratory stage. The economic loss caused by the production made many packaging companies stop; the original water-based composite glue (including various domestic manufacturers and international well-known brands) has very limited adaptability to the base material, and cannot meet the overall requirements of the pure aluminum structure composite process;

Abstract

The invention belongs to the field of water-based adhesives, and discloses a special water-based glue for aluminum foil compounding. The water-based glue is prepared through a seed emulsion polymerization method of monomers in the presence of a cross-linking agent, the monomers comprise 30-35 parts of an acrylate monomer, 1-3 parts of acrylic acid or methacrylic acid, 5-8 parts of methacrylate, 10-20 parts of styrene or acrylonitrile and 3-5 parts of hydroxyl acrylate, and the cross-linking agent is respectively added to a seed emulsion and a main body emulsion, wherein the seed emulsion contains 2-3 parts of N-hydroxyacrylamide or diacetone acrylamide; and the main body emulsion contains 1-1.5 parts of itaconic acid, ethylene glycol dimethacrylate or diallyl maleate. The water-based gluehas the advantages of reliable fastness, environmental protection during production and use, and reduction of the production cost. The invention also provides a method for producing the water-based glue.

Description

technical field [0001] The invention is a water-based adhesive, which is suitable for the composite field of aluminum foil and printed PET, BOPP, and PE or nylon. After compounding, it can meet the post-process requirements such as heat sealing and zipper installation below 300 degrees. It specifically relates to a special glue for water-based composite aluminum foil and its preparation method. Background technique [0002] The composite of aluminum foil and commonly used packaging film is mainly used in the packaging fields of food, medicine and cosmetics; at present, the glue used in the composite process of this type of structure adopts solvent-based two-component polyurethane adhesive, which cannot be achieved by ordinary water-based glue or solvent-free glue. To meet the requirements, there is no water-based adhesive for professional composite aluminum foil that meets the requirements of soft packaging companies on the market. The composite process of my country's soft...
