摘要
热塑性聚丙烯材料具有优异的电气性能和热性能,且生产过程无需交联和脱气,能耗低、可回收,与交联聚乙烯相比具有良好的环境友好性,是生产电力电缆的最佳材料之一。本文以聚丙烯材料为讨论对象,介绍了聚丙烯材料的基本结构和物理性质及其与电气性能的关系;着重论述了共聚改性、共混改性、化学改性和纳米颗粒改性等手段对聚丙烯材料结构、力学、热学和电气性能的影响;并对国内外聚丙烯电缆的研究进展和应用情况进行了综述;最后从聚丙烯材料的生产制备技术、结构与性能的关系以及改性手段等方面,对聚丙烯材料的未来发展进行了展望。
Thermoplastic polypropylene materials have excellent electrical properties and thermal properties,and their production process does not require cross-linking and degassing,with low energy consumption and recyclability.Compared with cross-linked polyethylene,it is environmentally friendly and one of the best materials for the production of power cable.Taking polypropylene materials as the discussion object,the basic structure and physical properties of polypropylene and their relationship with electrical properties were introduced in this paper.The effects of copolymerization modification,blending modification,chemical modification,and nano particle modification on the structure,mechanical,thermal and electrical properties of polypropylene were reviewed.The research progress and application of polypropylene cables at home and abroad were introduced.Finally,the furure development of polypropylene materials were summaried and prospected from the production and preparation technology of polypropylene,relationship between structure and properties,and modification techniques.
