摘要:

综述了近年来聚乙烯(PE)、聚丙烯(PP)、聚氯乙烯(PVC)、聚苯乙烯(PS)、乙烯?乙酸乙烯共聚物(EVA)、丙烯酸共聚物(EEA)等废旧塑料单独作为沥青改性剂及复配其他材料改性沥青的研究进展,并介绍了当前较具有发展前景的塑料裂解改性沥青技术;同时,总结了废旧塑料改性沥青的改性机理,包括溶胀机理、离析机理、储存稳定性机理等;最后,对废旧塑料改性沥青未来的发展趋势进行了展望。

Abstract:

This article reviewed the research progress in the modification of asphalts with asphalt polyethylene, polypropylene, polyvinyl chloride, polystyrene, ethylene?vinyl acetate copolymer, acrylic acid copolymer and other waste plastics as a modifier used alone and compounded with other materials in recent years. The plastic cracking and asphalt modification technologies with a promising development prospect were introduced, and meanwhile the relevant modification mechanisms were summarized, including swelling mechanism, separation mechanism, and storage stability mechanism. Finally, the future development trend in waste plastic?modified asphalts was prospected.

Key words: waste plastic, modification, asphalt, compounding, cracking, mechanism
