| 中文摘要: |
| 研究橡胶均匀分散剂FC-303在全钢载重子午线轮胎胎面胶中的应用，并与普通分散剂A50P进行对比。结果表明：在胎面胶中以分散剂FC-303替代分散剂A50P，胶料的门尼粘度明显降低，炭黑分散度提高；硫化胶的物理性能和耐热老化性能变化不大，压缩生热降低，耐磨性能提高；成品轮胎的耐久性能达到企业标准要求；分散剂FC-303的最佳用量为2份。 |
| 英文摘要: |
| The application of rubber dispersing agent FC-303 in the tread compound of truck and bus radial tire was investigated and compared to common dispersing agent A50P.The Mooney viscosity of the compound with FC-303 was significantly lower than that with A50P，and the dispersion of carbon black was better.The physical properties and aging property of the vulcanizates with FC-303 was similar to that with A50P，the compression heat build-up was lower，and the wear resistance was better.The endurance performance of the finished tire by using FC-303 to replace A50P in the tread compound met the requirements of enterprise standards.The optimal addition level of dispersing agent FC-303 was 2 phr. |
