摘要
废旧聚对苯二甲酸乙二醇酯(PET)排出量大,自然分解困难,循环利用废PET聚酯是解决环境污染问题和实现废物资源化利用的重要途径。本文介绍了废PET聚酯在制备单体原料、不饱和聚酯、涂料、增塑剂等方面的回收方法和发展现状,并对废PET聚酯回收再利用的前景进行了展望。
The discharge amount of waste polyethylene terephthalate （PET）, which is hard to decompose readily in nature, has been increasing rapidly in recent years. The recycling of PET is an effective way to solve environmental problems and to realize resource regeneration. This paper reviews the recycling method and current status of monomer preparation, unsaturated polyester, paint coatings and plasticizing agent from waste PET. In addition, the development prospect on waste PET recycling is forecasted.
