The invention discloses a wear-resistant flexible PEI cable material which comprises the following components in parts by weight: 20-35 parts of PEI resin, 35-55 parts of siloxane copolymerized PEI resin, 5-15 parts of wear-resistant modified resin, 8-15 parts of filler, 3-5 parts of compatilizer, 0.2-0.5 part of antioxidant, 0.1-0.3 part of light stabilizer and 0.2-0.6 part of lubricant; the melt index of the PEI resin is 8-20 g/10min @337 ℃/6.6Kg, the silicon content of the siloxane copolymerized PEI resin is more than 20%, and the melt index of the siloxane copolymerized PEI resin is 6-15 g/10min @295 ℃/6.6 Kg. The invention also discloses a preparation method of the PEI cable material and a cable prepared from the PEI cable material. The wear-resistant flexible PEI cable material is suitable for special cables which cannot meet the requirements of conventional cable materials and have high temperature resistance, cold resistance, high flame retardance, no toxicity and high tensile property. |
