| 中文摘要: |
| 研究硫化温度、压力和时间对绿色轮胎天然橡胶胎面胶的化学交联网络结构、物理性能、耐磨性能及动态性能的影响。结果表明：随着硫化温度升高，胶料的交联密度减小，耐磨性能先提高后下降，压缩疲劳温升提高，永久变形先增大后减小，60 ℃时的损耗因子（tanδ）增大；随着硫化压力升高，胶料的交联密度增大，定伸应力和拉伸强度提高，撕裂强度下降，抗裂口增长性能提高；随着硫化时间的延长，胶料的交联密度先提高后下降，撕裂强度和硬度下降，耐磨性能先提高后下降，压缩疲劳温升提高，60 ℃时的tanδ增大。 |
| 英文摘要: |
| The influence of curing temperature，curing pressure and curing time on the chemical cross-linked network，physical properties，abrasion resistance and dynamic mechanical properties of NR tread compound of green tire was investigated.The results showed that，with the increase of curing temperature，the crosslinking density decreased，abrasion resistance and permanent deformation increased at first and then decreased，and compression fatigue temperature rise and loss factor （tanδ）at 60 ℃ increased. As the curing pressure increased，the crosslink density，modulus at given elongation，tensile strength and anti-crack growth resistance increased，and tear strength decreased. With the curing time extending，the crosslinking density and abrasion resistance increased at first and then decreased，tear strength and hardness decreased，and compression fatigue temperature rise and tanδ at 60 ℃ increased. |
