| 中文摘要: |
| 研究新的胎侧配方以减轻黑胎侧污染。黑胎侧胶料一般是NR和BR并用，具有良好的耐天候老化、耐臭氧老化、抗撕裂、防龟裂性能及疲劳寿命，但现用的防护体系导致胎侧胶料表面变色、污染，通过改进胎侧的配方体系，采用NR，BR，CIIR和EPDM并用，不用防老剂以避免胎侧变色，达到胎侧无污染的目的。 |
| 英文摘要: |
| Various antioxidants are added to black NR/BR sidewall compound to obtain good weathering，ozone，tear and cracking resistances，as well as good fatigue property.A new black NR/BR/CIIR/EPDM sidewall compound without any antioxidant has been developed to eliminate the colour changing and staining of sidewall surface resulted from the existing antioxidants in traditional black NR/BR sidewall compound. |
