| 摘 要： | 研究了不同防老剂种类及用量，不同环境温度条件下，端羟基聚丁二烯（ＨＴＰＢ）液体橡胶粘度变化规律。结果表明，加入防老剂，尤其是２２４６可以显著改善ＨＴＰＢ的老化性能，且防老剂２２４６最佳用量为０．２％￣０．５％，室温下，ＨＴＰＢ不加防老剂的贮存期长达１年。

| Abstract: | The change law of the viscosity of hydroxylterminated polybutadiene(HTPB) liquid rubber was investigated with various kinds of antioxidants and its different contents at different environmental temperatures.The results showed that the aging properties of HTPB could be remarkably improved by adding antioxidants,especially antioxidant-2246,and the optimum content of antioxidant-2246 was 0.5 percent.The storage duration of HTPB was 1 year without the addition of antioxidants at room temperature. |
