热塑性聚丙烯电缆料研究进展评述

Review on Progress of Thermoplastic Polypropylene Cable Materials

  • 摘要: 交联聚乙烯(cross linked polyethylene, XLPE)是目前广泛应用的电力电缆绝缘材料,但由于其是热固性塑料,退役后难以回收利用,只能焚烧或掩埋,会造成不容忽视的环保问题,因此开发热塑性聚丙烯绝缘电力电缆显得尤为重要。为促进聚丙烯电缆料的开发,需要对聚丙烯材料的关键技术研究和应用现状进行系统评述。该文总结了近几年聚丙烯电缆料的研究热点,包括聚丙烯电缆料结构与性能的关联、机械共混和直接合成的性能提升对比,分析认为,以聚丙烯为基体的环保型电缆料展现出了很好的应用前景,但是实现工业化应用仍需要开展大量的研究工作,其中化工合成是聚丙烯电缆料开发的重要手段,同时也需要采用复配技术进行补充。最后,从工程实际角度总结了热塑性聚丙烯电缆料还需要突破的技术瓶颈和方向:加工成型、匹配性和稳定性问题。在未来的应用过程中还应注重材料老化评估研究,提升新型电力电缆应用的可靠性。

     

    Abstract: Cross linked polyethylene (XLPE) is a widely used insulating material for power cables at present. However, it is difficult to recycle after retirement of thermosetting plastic, and it can only be burned or buried, which will cause environmental problems that cannot be ignored. It is particularly important to develop thermoplastic polypropylene insulated power cables. In order to promote the development of polypropylene cable insulating materials, it is necessary to systematically review the research status of polypropylene materials. This paper summarizes the research hotspots of polypropylene insulated cable in recent years, including the relationship between the structure and performance of polypropylene cable insulation, the comparison of performance improvement between mechanical mixing and industrial synthesis. It is believed that the environment-friendly cable based on polypropylene has a great application prospect, however, a lot of research work is needed to realize industrial application, of which chemical synthesis is an important means of developing polypropylene insulated cable. At the same time, the composite technology is also needed to supplement. Finally, from the perspective of engineering practice, this paper summarizes the technical problems and directions that thermoplastic polypropylene cable materials need to break through: processing, matching and stability. In the future, the material aging evaluation research should focus on improving the reliability of the new power cables.
