摘要
ＰＶＣ经交联后，其热性能、电性能、机械性能均大幅度提高，材料使用耐温等级亦相应提高．与传统的化学交联相比，采用高能电子射线进行的辐射交联方法具有产品质量好、生产工艺简单、生产效率高、能耗低、环境污染小等优点．文中综述了在多官能团单体交联剂存在下，以高能电子射线对ＰＶＣ进行辐射交联的基本原理、交联产品的性能及交联生产的工艺特点，比较了辐射交联与化学交联之间的优缺点，总结了近年来ＰＶＣ辐射交联技术在理论及工业应用中的最新进展，并介绍了辐射交联ＰＶＣ材料在电线电缆、建筑材料等领域的应用．
The radiation crosslinking of plasticized polyvinyl chloride (PVC) was reviewed, which includes fundamental principles of crosslinking reaction, characteristics of crosslinked products, handling technology in industrial processing and advantages of radiation crosslinking over chemical crosslinking methods. The latest development of PVC radiation crosslinking in theory and industry application was summarized. The uses of radiation crosslinked PVC materials in some fields, such as wire and cable insulation, construction materials etc., were also introduced.
