摘要
塑料制品的不规范生产、使用以及回收不当等,会造成能源资源浪费和环境污染.推广可降解塑料替代产品是解决塑料污染问题的重要途径之一.目前,生物可降解塑料仅用于薄膜、吸管等一次性制品,需求量更大的缓冲包装领域尚未有规模化应用.近年来,绿色环保的超临界流体发泡技术制备的生物可降解塑料泡沫成为了学术界和工业界关注的热点,基于此,笔者总结了超临界流体发泡制备生物可降解塑料泡沫方面的应用进展,简述了间歇发泡、挤出发泡、注塑发泡、珠粒发泡制备生物可降解塑料泡沫的发泡工艺和结构性能,重点综述了聚乳酸、聚对苯二甲酸-己二酸丁二酯、聚丁二酸丁二酯泡沫材料的研究现状.
Abstract
The improper production,use,and recycling of plastic products lead to energy resource waste and environmental pollution.Promoting the use of biodegradable plastics as alternatives is one of the crucial approaches to address plastic pollution.Currently,biodegradable plastics are mainly utilized in disposable items such as films and straws,with limited applications in the larger-scale buffer packaging sector.In recent years,the application progress of green and environmentally friendly supercritical fluid foaming technology in preparing biodegradable foam materials has attracted attention from both academia and industry.The application progress of supercritical fluid foaming in the preparation of biodegradable plastic foam was summarized.The foaming processes,structural properties of biodegradable foam materials prepared by batch foaming,extrusion foaming,injection foaming and bead foaming were briefly described.The research status of foam materials based on polylactic acid,poly(butylene adipate-co-butylene terephthalate)and poly(butylene succinate)was reviewed.
