| 中文摘要: |
| 研究炭黑N339在全钢载重子午线轮胎胎面胶中的应用。结果表明：与加入52份炭黑N220的胶料相比，采用炭黑N339替代50%或全部替代炭黑N220的胶料的硫化速率增大，硫化胶的硬度和300%定伸应力增大，压缩生热分别减小3.8和4.5 ℃，耐磨性能提高；当炭黑N339和炭黑N220用量比为1/1时，硫化胶的滚动阻力低、动态生热小，成品轮胎的耐久性能优异，高速性能相当。 |
| 英文摘要: |
| The application of carbon black N339 in the tread compound of all-steel truck and bus radial tire was studied.The results showed that，compared with the compound containing 52 phr carbon black N220，the vulcanization rate of the compound using carbon black N339 instead of 50% or all of carbon black N220 increasesd，the hardness and modulus at 300% elongation of the vulcanizate increased，the compression heat build-up decreased by 3.8 and 4.5 ℃，respectively，and wear resistance was improved.When the mass ratio of carbon black N339 to carbon black N220 was 1/1，the rolling resistance of the vulcanizate decreased，dynamic heat generation decreased，and the durability of the finished tire was excellent，with comparable high-speed performance. |
