摘要
介绍了聚乙烯材料光氧老化和热氧老化的老化机理,综述了国内聚乙烯光氧老化、热氧老化和耐候性能的研究进展。通过对聚乙烯在室外环境中老化性能的研究,准确掌握了聚乙烯的老化性能,为聚乙烯寿命评估提供可靠的技术支持。
The aging mechanism of photo oxidation and thermal oxidative aging of polyethylene materials was introduced. The research progress of photo oxidation aging, thermo oxidative aging and weather resistance of polyethylene in China was reviewed. Through the study on the aging performance of polyethylene in the outdoor environment, the aging properties of polyethylene are accurately mastered, which could provide reliable technical support for the life evaluation of polyethylene.
