| 中文摘要: |
| 研究密炼机残余密封油（简称再生油）在全钢载重子午线轮胎中的应用。结果表明：随再生油用量的增大，全钢载重子午线轮胎胎体帘布胶和胎面胶的门尼粘度、FL和Fmax减小，焦烧时间延长，硫化速度变化不明显；硫化胶的定伸应力、拉伸强度、撕裂强度和压缩生热减小，拉断伸长率增大，密度和硬度变化不大；当在胎体帘布胶中添加3份再生油时，成品轮胎性能达标同时可降低成本。 |
| 英文摘要: |
| The application of residual sealing oil of mixer （recycled oil for short） in truck and bus radial tire was investigated.The results showed that，with the increase of the amount of recycled oil，the Mooney viscosity，FL and Fmax of carcass ply and tread compound of truck and bus radial tire were decreased，scorch time was prolonged and curing rate changed little.The modulus，tensile strength，tear strength and compression heat built-up of vulcanizate were decreased，while the elongation at break was increased，and the density and hardness did not change much.When 3 phr recycled oil was used in the carcass ply compound，the performance of the finished tire reached the standard and the cost reduced at the same time. |
