| 目的 为包装废聚对苯二甲酸乙二醇酯(PET)的回收和高值转化提供有效参考和依据。方法 通过梳理废PET来源，对比分析不同PET发泡工艺方法及其利弊，分析不同发泡剂的发泡效果，并研究PET的发泡改性途径，进而总结废PET发泡后的应用领域和发泡工艺的发展趋势。结果 近年来废PET发泡材料的研究已取得很大进展，但发泡材料的性能优化仍需进一步探究。结论 大量相关文献证明了利用包装废PET制备发泡材料的可行性，废PET发泡材料的研发符合循环发展的理念，这为废PET的回收和高值转化提供了更多的有效途径，具有广阔的发展前景。 |
| 英文摘要: |
| The work aims to provide an effective reference pathway and basis for the recycling and high-value conversion of packaging waste polyethylene terephthalate (PET). By summarizing the sources of waste PET, comparing and analyzing different PET foaming process methods and their advantages and disadvantages, analyzing the foaming effect of different foaming agents, and studying the modification methods of PET foaming, the application fields of foam materials derived from waste PET and the development trend of foaming process were summarized. The researches on foam materials derived from waste PET have made great progress in recent years, but the performance optimization of foams still needs to be further explored.A large amount of relevant literature prove the feasibility preparing foaming materials with packaging waste PET. The development of waste PET based foaming materials is in line with the concept of recycling development. It provides more effective ways for recycling and high-value conversion of waste PET, and has a broad development prospect. |
