| 中文摘要: |
| 研究甲基丙烯酸甲酯接枝改性的天然橡胶（NR）MG-30和树枝状聚酰胺-胺（PAMAM）对全钢子午线轮胎胎面胶耐磨性能的影响。结果表明：与生产配方胶料相比，加入MG-30后的NR胶料的门尼特性和硫化特性均无明显变化、物理性能有所提高，但邵尔A型硬度增大；加入PAMAM后，NR/MG-30并用胶的物理性能和耐磨性能明显提高，邵尔A型硬度减小。 |
| 英文摘要: |
| The effect of methyl methacrylate grafted NR MG-30 and dendritic PAMAM on the wear resistance of radial tire tread compound was investigated.The results showed that，compared with that of current product，the Mooney characteristics and curing behavior of NR/MG 30 blend changed little，the physical properties were improved，but the shore A hardness increased.The physical properties and wear resistance of NR/MG-30 blend were improved significantly by adding PAMAM，and the shore A hardness decreased. |
