摘要（英）：

The invention discloses a high-tear-resistance nitrile-butadiene rubber material for nuclear power station cables and a preparation method thereof. The high-tear-resistance nitrile-butadiene rubber material for nuclear power station cables is prepared from the following raw materials in parts by weight: 47-63 parts of nitrile-butadiene rubber, 20-30 parts of polyether compounded polyurethane rubber, 14-22 parts of high styrene rubber, 18-24 parts of meerschaum wool, 5-10 parts of barium stannate, 2-5 parts of zinc dimethyl acrylate, 1-3 parts of dibasic lead phosphite, 3-6 parts of tert-dodecylmercaptan, 2-4 parts of ethyl crotonoleate, 15-25 parts of nano diamond, 2-3 parts of isopropylxanthic disulfide, 4-8 parts of precipitated sulfur, 1-2 parts of bis neopentyl glycol dithiopyrophosphate, 4-6 parts of p-tert-octyl phenol formaldehyde resin, 2-3 parts of 2-thioimidazoline, 1-2 parts of N-phenyl-1-naphthylamine and 15-20 parts of vitrified powder. The high-tear-resistance nitrile-butadiene rubber material for nuclear power station cables has the advantages of higher aging resistance, higher hardness, higher rigidity, higher mechanical strength and higher tear strength.
