| 中文摘要: |
| 介绍常用的橡胶低温性能的表征检测方法，并从轮胎的使用过程出发推荐采用脆性温度表征其低温性能。将根据粘弹谱仪所测损耗因子-温度曲线确定的特性温度与脆性温度相比较，发现损耗因子-温度曲线在玻璃化温度以下的拐点处两切线交点对应温度与脆性温度高度吻合，可以用来表征胎面胶的耐低温性能。 |
| 英文摘要: |
| The main characterization methods on low temperature resistance of rubber were introduced.Typically，the characteristic temperature of tire compound could be determined as the cross point of two tangent lines on the temperature dependence curve of loss factor measured by dynamic viscoelastometer.It was found that this characteristic temperature was in good accordance with the brittleness temperature of the compound.Thus the brittleness temperature could be used to evaluate low temperature resistance of tire. |
