Abstract:

The effects of ethylene⁃octene copolymer grafted acrylonitrile (POE⁃g⁃AN) oil⁃resistant compatibilizer on oil resistance, mechanical properties and electrical properties of EVA/PE⁃LLD cable materials were studied. The results showed that with the increase of the amount of POE⁃g⁃AN, the tensile strength, oil resistance and electrical properties of the material all showed a trend of increasing or decreasing first, while the elongation at break increased continuously. When the amount of the graft was 6 wt%, The interphase compatibility improvement effect is the best. At this time, the oil resistance of the modified cable material:the absolute value of the tensile strength, the absolute value of elongation at break, the absolute value of mass and volume change rate is the smallest, which are 35.7 %, 34.6 %, 15.69 %,15.35 %,and the tensile strength increased by 8.5 % to 13.02 MPa, and the elongation at break was 274.15 %; the maximum DC breakdown field strength was 199 kV/mm, and the maximum volume resistivity was 7.84×1012 Ω·m.
