一种超耐低温耐臭氧改性橡胶
摘要：
本发明公开了一种超耐低温耐臭氧改性橡胶，包括如下质量份数的组分：丁腈橡胶95～105份、聚氯乙烯15~30份、炭黑60～90份、二氧化硅5~15份，葵二酸二辛脂10～20份、氧化锌5～12份、硬脂酸0.5～2份、硫磺0.5~1.5份、硫脲防老剂1.5~3.0份、微晶石蜡3.0~5.0份、N-环已基-2-苯并噻唑次磺酰胺1.2~2.5份。本发明所提供的改性橡胶，能够大幅度提高产品耐臭氧、耐低温性能，显著延长橡胶制品在低温、高臭氧浓度下的使用寿命。
摘要（英）：

The invention discloses an ultralow-temperature-resistant ozone-resistant modified rubber which comprises the following components in parts by mass: 95-105 parts of nitrile-butadiene rubber, 15-30 parts of polyvinyl chloride, 60-90 parts of carbon black, 5-15 parts of silicon dioxide, 10-20 parts of dioctyl sebacate, 5-12 parts of zinc oxide, 0.5-2 parts of stearic acid, 0.5-1.5 parts of sulfur, 1.5-3.0 parts of thiocarbamide anti-aging agent, 3.0-5.0 parts of microcrystalline wax and 1.2-2.5 parts of N-cyclohexyl-2-benzothiazole sulfenamide. The modified rubber disclosed by the invention can greatly enhance the ozone resistance and low-temperature resistance of the product and obviously prolong the service life of the rubber product under the conditions of low temperature and high ozone concentration.
