Abstract

The invention discloses a high-toughness packaging material which sequentially comprises an aluminum foil composite film layer, an adhesive layer and a cyclopentadiene film layer from inside to outside. The adhesive layer is prepared by the following steps: adding dipropanediol diacrylate and maleic anhydride into butanone, and reacting under reflux for 50 minutes; adding tetrazole and ethoxylated trimethylolpropane triacrylate, and reacting under reflux for 20 minutes; sequentially adding 1,3,5-triglycidyl-S-triazinyltrione and diethyl phosphite, and reacting under reflux for 2 hours; adding cyanochitosan, polydimethylsiloxane and 2-hexanone, and reacting under reflux for 1.5 hours; and finally, adding rubidium carbonate, continuing reacting for 1 hour to obtain the adhesive layer. By using the reasonable structural design and adhesive layer, the high-toughness packaging material disclosed by the invention has the advantages of favorable mechanical strength, high temperature resistance, favorable packaging protecting property, no pollution and the like, and is convenient to use.

Description

technical field [0001] The invention relates to the technical field of packaging materials, in particular to a high-toughness packaging material. Background technique [0002] Materials are the pillars of modern science and technology and social development, and the competition of modern high technology depends to a large extent on the development of material science. The so-called macromolecule usually refers to a macromolecular compound composed of tens of millions of small molecular compounds connected by chemical bonds. General-purpose polymer materials are divided into five categories: plastics, rubber, fibers, adhesives, and coatings. Composite materials are multiphase materials prepared by compounding two or more materials such as metal materials, ceramic materials or polymer materials. Various materials learn from each other in terms of performance and produce synergistic effects. The performance is superior to the original constituent materials and meets various r...
