| 中文摘要: |
| 研究热裂解炭黑在全钢载重子午线轮胎胎踵胶中的应用。结果表明：在胎踵胶中以10份热裂解炭黑替代5份炭黑N330，胶料的加工性能和物理性能基本相当，损耗因子和压缩永久变形减小；成品轮胎的耐久性能性能良好，同时有效降低了胎踵胶的成本。 |
| 英文摘要: |
| The application of pyrolytic carbon black in bead heel componnd of all-steel truck and bus radial tire was studied.The results showed that replacing 5 phr of carbon black N330 with 10 phr of pyrolysis carbon black in the bead heel componnd，the processability and physical properties of the compound were basically equivalent，the loss factor at 60 ℃ and the compression set decreased，the durability performance of finished tires were good，while the cost of the bead heel compound was effectively reduced. |
