Abstract

The invention relates to an adjustable performance irradiation crosslinking ethylene-tetrafluoroethene copolymer insulation material, which comprises the following components by mass part: an ethane-tetrafluoroethene copolymer, a cross-linking agent, N,N-'-dis[beta-(3,5-di-tert-butyl-4-hydroxyphenyl)propionyl]hydrazine, 1,3,5-tri(3,5-di-tert-butyl-4-hydroxyphenyl)isocyanuric acid, antimonony oxide, N, N'-ethylene bis-stearamide, and white oil, the cross-linking agent is made by mixing a component A and a component B, the mass ratio of the component A: the component B is 1: 0.1-10; the component B is at least one of triene propyl isocyanate, TMAIC, triallyl cyanate ester and TMAIC. The fluorine-containing polymer has the advantages of difficult self-polymerization, low volatileness, increased product stability, difficult volatileness, difficult self-polymerization, little smoke amount during the processing process, white sample color, non discolouring after irradiation and good product stability.

Description

technical field [0001] The invention relates to the technical field of ethylene-tetrafluoroethylene copolymer insulation materials, in particular to radiation crosslinked ethylene-tetrafluoroethylene copolymer insulation materials. Background technique [0002] Ethylene-tetrafluoroethylene copolymer (ETFE), also known as F40, has a melting point of 265-280°C and is the strongest and lightest fluoroplastic. ETFE has excellent dielectric, insulating and mechanical properties, radiation resistance, crack resistance, aging resistance, various chemical solvent resistance, high and low temperature resistance, long-term working temperature between -65°C and 150°C. After ETFE resin is irradiated and cross-linked, its radiation resistance, tensile strength and aging resistance are greatly improved, and its long-term working temperature is increased to 200°C. It is widely used in special cable insulation materials, such as transportation, aviation, chemical and nuclear plants, Insula...
