| 中文摘要: |
| 研究溶聚丁苯橡胶（SSBR） SL PBR 4089在全钢载重子午线轮胎胎面胶中的应用。结果表明：随着SSBR SL PBR 4089用量的增大，胶料的门尼粘度有所提高，加工性能略差；撕裂强度、300%定伸应力、拉伸强度和拉断伸长率呈降低趋势，生热和滚动阻力减小。在胎面胶中添加23份SSBR SL PBR 4089，胶料老化前的DIN磨耗量降低约25%，阿克隆磨耗量降低约33%。 |
| 英文摘要: |
| The application of SSBR SL PBR 4089 in the tread compound of all-steel truck and bus radial tire was investigated.The results showed that when the additional level of SSBR SL PBR 4089 increased，the Mooney viscosity of the compound was higher，the processing properties were slightly decreased，the tear strength，modulus at 300% elongation，tensile strength and elongation at break also showed the trend of decrease in general，and the heat build-up and rolling resistance were reduced.With 23 phr SSBR SL PBR 4089，before aging，the DIN abrasion loss of the vulcanizate was reduced by 25% and Akron abrasion loss was reduced by 33%. |
