| 中文摘要: |
| 研究改性203树脂在半钢子午线轮胎胎侧胶中的应用。结果表明，在半钢子午线轮胎胎侧胶中使用改性203树脂等量替代R7510H树脂，胶料的焦烧时间略延长， t 90 略缩短，表面初始粘性和粘性保持率均有所提高，硫化胶60 ℃时的损耗因子明显减小，压缩疲劳温升和滚动阻力降低，其他物理性能相差不大。 |
| 英文摘要: |
| The application of modified 203 resin in sidewall compound of steel-belted radial tire was studied.The results showed that，the modified 203 resin was used to equivalently replace the R7510H resin in the sidewall compound of steel-belted radial tire，the scorch time of the compound was slightly prolonged，the t 90 was slightly shortened，and the surface initial viscosity and viscosity retention rate of the vulcanizate increased，the loss factor at 60 ℃ was reduced，the temperature rise of compression fatigue decreased，and other physical properties were similar. |
