| 中文摘要: |
| 在全钢载重子午线轮胎胎面胶中加入不同用量炭黑N234，并将白炭黑与炭黑并用，考察炭黑用量和添加白炭黑对胶料性能的影响。结果表明：随着炭黑N234用量增大，不添加白炭黑的胶料Fmax和门尼粘度增大，门尼焦烧时间呈缩短趋势；密度、硬度和定伸应力提高，拉伸强度和回弹值降低，撕裂强度先提高后降低，耐磨性能提高，生热增大，炭黑用量不宜过大；在填料用量相当的条件下，添加白炭黑的胶料门尼粘度较小，门尼焦烧时间较短，撕裂强度和耐磨性能显著提高，生热明显降低；随着炭黑用量增大，不添加白炭黑的胶料弹性模量和损耗因子总体提高；总体来看，添加45份炭黑N234和10份白炭黑的胎面胶，滞后损失和生热较低。 |
| 英文摘要: |
| Different amount of carbon black N234 or carbon black/silica were added into the tread compound of truck and bus radial tire.The effects of the amount of carbon black and the addition of silica on the properties of the tread compound were investigated.The results showed that，as the amount of carbon black N234 increased，Fmax and Mooney viscosity of the compound without silica improved，Mooney scorch time was shortened，density，hardness and modulus were improved，tensile strength and rebound value were reduced，tear strength was improved firstly and then went down，wear resistance was improved，and heat built-up increased.Therefore，the amount of carbon black should not be too high.With the equivalent amount of fillers，Mooney viscosity of the compound with silica was lower，the Mooney scorch time was shorter，tear strength and wear resistance were improved obviously，and the heat build-up decreased.As the amount of the carbon black increased，the elastic modulus and loss factor of the compound without silica were generally improved.Generally，the hysteresis loss and heat build-up of the compound with 45 phr carbon black N234 and 10 phr silica reduced obviously. |
