耐辐照交联乙烯-四氟乙烯共聚物绝缘料

本发明涉及一种耐辐照交联乙烯-四氟乙烯共聚物绝缘料，包括以下质量份的组分：乙烯-四氟乙烯共聚物100份，交联剂3～8份，N,N'-双[β-(3，5-二叔丁基-4-羟基苯基)丙酰]肼0.1～1份，1,3,5-三(3,5-二叔丁基-4-羟基苄基)异氰尿酸0.3～3份，五氧化二锑1～3份，N,N'-乙撑双硬脂酰胺0.1～2份，季戊四醇硬脂酸酯0.1～0.5份，耐辐照组分2～10份，白油0.1～3份。本发明能更加稳定、高效的提升交联乙烯-四氟乙烯共聚物绝缘料耐辐照性能。 The invention relates to an irradiation-resistant cross-linked ethylene-tetrafluoroethylene copolymer insulating material. The insulating material comprises the following components in parts by mass:100 parts of an ethylene-tetrafluoroethylene copolymer, 3 to 8 parts of cross-linking agent, 0.1 to 1 part of 1,3,5-tri(3,5-di-tert-butyl-4-hydroxyphenyl)propionyl]hydrazine, 0.3 to 3 parts of 1,3,5-tri(3,5-di-tert-butyl-4-hydroxybenzyl)isocyanuric acid, 1 to 3 parts of antimony pentoxide, 0.1 to 2 parts of N,N'-ethylenebisstearamide, 0.1 to 0.5 part of pentaerythritol stearate, 2 to 10 parts of an anti-irradiation component, and 0.1 to 3 parts of white oil. The irradiation resistance of the crosslinked ethylene-tetrafluoroethylene copolymer insulating material can be more stably and
