NOVELTY - A wind-power generating cable sheath rubber material comprises 50-70 pts. wt. styrene-butadiene rubber, 10-18 pts. wt. butadiene rubber, 20-32 pts. wt. natural rubber, 15-20 pts. wt. organic-modified montmorillonite, 1-1.5 pts. wt. magnesium oxide, 0.8-1.3 pts. wt. zinc oxide, dicumyl peroxide, triallyl propyl isocyanurate, dibutyl adipate, ethyl oleate, hazelnut oil, stearic acid, carbon black, purple carbon black, N-cyclohexyl-2-benzothiazole sulfonamide, tetramethylthiuram disulfide, N-isopropyl-N'-phenyl-p-phenylenediamine and N-phenyl-2-naphthylamine.    USE - Wind-power generating cable sheath rubber material (claimed).    ADVANTAGE - The wind-power generating cable sheath rubber material has excellent rebound resilience, low-temperature characteristics and flame retardance.    DETAILED DESCRIPTION - A wind-power generating cable sheath rubber material comprises 50-70 pts. wt. styrene-butadiene rubber, 10-18 pts. wt. butadiene rubber, 20-32 pts. wt. natural rubber, 15-20 pts. wt. organic-modified montmorillonite, 1-1.5 pts. wt. magnesium oxide, 0.8-1.3 pts. wt. zinc oxide, 1.5-2.8 pts. wt. dicumyl peroxide, 0.3-0.8 pts. wt. triallyl propyl isocyanurate, 1-3 pts. wt. dibutyl adipate, 0.8-2.2 pts. wt. ethyl oleate, 5-8 pts. wt. hazelnut oil, 1.2-1.6 pts. wt. stearic acid, 20-35 pts. wt. carbon black, 10-15 pts. wt. purple carbon black, 1-1.5 pts. wt. N-cyclohexyl-2-benzothiazole sulfonamide, 0.5-1.6 pts. wt. tetramethylthiuram disulfide, 1.8-2.2 pts. wt. N-isopropyl-N'-phenyl-p-phenylenediamine and 0.4-0.8 pts. wt. N-phenyl-2-naphthylamine. The organic-modified montmorillonite is obtained by mixing 100 pts. wt. water and 8-15 pts. wt. sodium montmorillonite, stirring for 4-6 hours, separating the reaction solution, heating the supernatant solution at 85-100 degrees C, adding 3-6 pts. wt. octadecyltrimethylammonium chloride, ultrasonically-treating for 60-80 minutes, stirring for 3-5 hours, filtering, washing and drying. An INDEPENDENT CLAIM is included for manufacture of wind-power generating cable sheath rubber material.
