摘　　要：电线电缆是输送电能、传送信息和制造各种电机、电器、仪表、汽车、机床等设备所不可缺少的基础器材,是电气化、信息化社会中必要的基础产品。我国作为全球第一大电线电缆生产国,行业产值在电工电器行业中仅次于汽车行业。作为重要的基础性产业,电线电缆行业被喻为国民经济的“血管”和“神经”,在我国国民经济中占有很重要的地位,肩负着为各行各业国民经济支柱行业配套的职能。电线电缆广泛应用于国民经济各个领域,但是在一些特殊的应用领域如航空航天、机车车辆、能源、钢铁、有色金属冶炼、石油开采、核电站等,传统的聚氯乙烯(PVC)、聚乙烯(PE)等材料无法满足使用要求,而含氟材料乙烯-三氟氯乙烯共聚物(ECTFE)及其改性树脂具有优异的电性能、防火性能、耐热性、耐候性及耐化学性,作为电线电缆的绝缘层和护套材料正好可以满足这些特殊领域的使用要求。乙烯-三氟氯乙烯共聚物(ECTFE)是乙烯与三氟氯乙烯以1∶1的物质的量比共聚制得的交替共聚物,是一种半结晶、可熔融加工的含氟聚合物。目前,国内外ECTFE的制备方法主要有悬浮聚合法、乳液聚合法、溶液聚合法。文章主要介绍了国内外ECTFE的制备方法及各种制备方法的优缺点,并介绍了ECTFE在电线电缆上的应用进展。Electric wires and cables are indispensable basic equipment for the transmission of electric energy,information,and also for the manufacture of various electrical machinery,electrical appliances,automobiles and other equipment,and are necessary basic products in the electrified and information society.As the world’s largest wires and cables producer,China’s industrial output value in the electrical industry is second only to the automobile industry.As an important basic industry,the wires and cables industry is regarded as the“blood vessel”and“nerve”of the national economy.It plays a very important role in the national economy of China and shoulders the function of supporting the pillar industries of the national economy of all walks of life.Wires and cables are widely used in each domain of national economy,but in some special field of application,the traditional polyvinyl chloride(PVC),polyethylene(PE),and other materials can not meet the request for utilization,but ethylene-chlorotrifluoroethylene copolymer(ECTFE)and its modified resins have excellent electric properties,fire prevention performance,heat resistance,weather resistance and chemical resis-tance,which can meet the requirements of use as wires and cables insulation and sheath material.Ethylene-trifluoroethylene copolymer(ECTFE)is a semi-crystalline,melt-processable fluoropolymer.At present,the main preparation methods of ECTFE at home and abroad include suspension polymerization,emulsion polymerization and solution polymerization.This paper mainly introduces the preparation of ECTFE at home and abroad,and the advantages and disadvantages of various preparation methods,and its application in electric wires and cables.
