Abstract

The invention discloses a preparation method of a polymer packaging material. The preparation method is characterized by comprising the following steps: S1, preparation of an intermediate product; S2,preparation of fluorine-containing sulfuryl vinyl modified hydroxyl-terminated hyperbranched polycarbonate; S3, preparation of an acrylonitrile/caffeic acid/2,2-dimethylvinyl boronic acid pinacol ester copolymer; S4, molding of the packaging material; and S5, radiation crosslinking. The invention further provides the polymer packaging material prepared according to the preparation method of the polymer packaging material. The polymer packaging material provided by the invention is better in comprehensive performance, better in antibacterial property, corrosion resistance, wear resistance andmechanical strength, more excellent in moisture resistance, gas resistance and oxidation resistance and safer and more environment-friendly to use.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a polymer packaging material and a preparation method thereof. Background technique [0002] Packaging materials refer to the materials used to make packaging containers, packaging decoration, packaging printing, packaging and transportation to meet product packaging requirements, including metal, plastic, glass, ceramics, paper, bamboo, wild mushrooms, natural fibers, Chemical fibers, composite materials and other main packaging materials are indispensable products in life and production. An ideal packaging material can not only play an aesthetic role, but also maintain the safety, stability and effectiveness of the packaged items. Therefore, it is particularly important to develop packaging materials with excellent comprehensive properties. [0003] Polymer packaging materials are a kind of packaging materials made of polymer materials. Due to their good mechanical ...
