| 中文摘要: |
| 研究新型芳纶浆粕（超细）纤维对NR/BR胎面胶的补强性能。结果表明，芳纶浆粕纤维补强的NR/BR硫化胶具有良好的模量-滞后平衡效应，加入3份芳纶浆粕纤维能将硫化胶20％应变的拉伸模量提高近2倍，0 ℃时的损耗因子增大而60 ℃时的损耗因子略有减小，对胶料的加工性能几乎没有影响。低用量芳纶浆粕纤维补强的NR/BR并用胶较适用于轮胎胎面胶。 |
| 英文摘要: |
| The reinforcement of a new type of aramid pulp superfine short fibres to NR/BR tire tread was investigated. The results showed that the NR/BR vulcanizate reinforced by aramid pulp superfine short fibres had good modulus-hysteresis balance； by using 3 phr aramid pulp fibre， tensile modulus at 20% elongation of the vulcanizate increased by about 2 times， tanδ at 0 ℃ increased，and tanδ at 60 ℃ decreased slightly， and at the same time the processibility of the compound changed little. The NR/BR blend reinforced by aramid pulp superfine short fibres could be used in the tire tread. |
