防老剂HS-911和RD在轮胎胶料中的比较

Comparison of Antioxidant HS-911 and RD in rubber compounds for tire

防老剂HS-911是一种新型的无毒、非污染性、高效的二苯胺类防老剂。以防老剂RD为参照,测试和研究了HS-911和RD在内胎胶、胎侧胶和胎面胶3种轮胎胶料的性能。实验结果表明,HS-911可代替RD在内胎胶、胎侧胶和胎面胶中应用,特别是具有比较好的热空气老化性能,但屈挠龟裂后期性能不如RD。

The Antioxidant HS-911 is a new kind of Diphenylamine Antioxidant which is non-poisonous,non-staining and high-efficiency. As the contrasts used the compounds with Ant ioxidant RD, the properties of inner tube,sidewall and treadrubber compound with Antioxidant HS-911 and RD were tested and studied .The results show that HS-911 can replace RD to be used in inner tube,sidewall and tread rubber compound. Especially, the air oven ageing properties of the compounds with HS-911 are better than with RD,but the post properties of flex cracks are not as good as with RD.
