铝塑复合包装的应用及废弃物回收利用新技术

Application of aluminum-plastic packaging and new recycling technology of the waste

包装是商品使用、储存、运输的重要保障,不可或缺。塑料包装轻质、易加工、性价比高,增长极快,成为现代社会主要的包装材料,其中铝塑复合包装通过材料优势互补,可满足阻隔性、抗菌性、力学性能和印刷性能等多功能要求,应用广泛,但即用即弃,废弃物难分离难回收利用,无法降解,也难焚烧处理,污染环境,浪费资源,亟待治理。本文综述了铝塑复合包装结构性能和应用,以及废弃物回收利用难点,重点介绍了本团队采用自主创新的固相剪切碾磨加工装备和技术,实现废弃铝塑复合包装的室温超细粉碎和均匀分散,改善加工性和力学性能,制备可拆卸物流包装箱及导热导电功能制品的研究工作。

Packaging is an important guarantee for the use,storage and transportation of products.Due to the lightweight,easy processing and high performance,plastic packaging become the main packaging material in modern society.Aluminum-plastic packaging has the advantages of plastic and aluminum,which meet the barrier,antimicrobial,mechanical and printing performance for multi-functional requirements.However,the fast development and single-use of aluminum-plastic packaging cause serious environmental problems and waste of resources.Aluminum-plastic packaging waste is difficult to separate for recycling,unable to degrade,and difficult to burn,so the caused pollution becomes an urgent problem to be solved.This article introduced the structure,properties and application of aluminum-plastic packaging,and the challenges in waste recycling.We emphatically introduced the works focused on self-designed solid-state shear milling equipment and technology,which achieved ultra-fine grinding and excellent dispersion of waste aluminum-plastic packaging at room temperature.We further produced removable logistics packages and thermal conductive function products by aluminum-plastic packaging powder with improved processability and mechanical properties.
