| 中文摘要: |
| 研究非标准炭黑在轿车子午线轮胎胎侧胶中的应用。结果表明：与填充炭黑N330的胶料相比，填充非标炭黑BC2123胶料的门尼粘度、门尼焦烧时间和硫化速度相当，挤出口型膨胀率较小，具有更好的炭黑分散性；密度、硬度和耐屈挠性能相当，定伸应力和拉伸强度稍有提升，拉断伸长率和撕裂强度略有下降，具有更好的高低温弹性、更低的生热和更小的损耗因子；以非标准炭黑BC2123减量替代炭黑N330，成品轮胎的滚动阻力降低。 |
| 英文摘要: |
| The application of non-standard carbon black in the sidewall compound of passenger car radial tire was studied.The results showed that compared with the compound filled with carbon black N330，the Mooney viscosity，Mooney scorch time and curing speed of the compound filled with non-standard carbon black BC2123 were comparable，the extrusion die expansion rate was smaller，and the dispersion of carbon black was better.The density，hardness and flexural resistance of the compound filled with non-standard carbon black BC2123 were comparable，the modulus and tensile strength were slightly improved，the elongation at break and tear strength were slightly decreased，the high and low temperature elasticities were better，and the heat build-up and loss factor were smaller.By replacing carbon black N330 with non-standard carbon black BC2123，the rolling resistance of the finished tire was reduced. |
