| 中文摘要: |
| 采用湿法工艺对硬质炭黑N234进行表面改性，研究改性炭黑N234在全钢子午线轮胎胎面胶中的应用。结果表明：采用协效性双组分改性剂SF/SE（均为中分子水油两亲非离子型硼酸酯）体系对炭黑N234的改性效果优于单组分改性剂SF，改性炭黑N234较未改性炭黑N234在橡胶基体中的分散性提高；与添加未改性炭黑N234的胶料相比，添加改性炭黑N234的胶料的门尼粘度大幅降低，拉伸性能、抗撕裂性能、耐磨性能和耐热老化性能提高，压缩疲劳温升降低。 |
| 英文摘要: |
| The surface modification of hard carbon black N234 was carried out by wet process，and the application of modified carbon black N234 in the tread of all-steel radial tire was studied. The results showed that the modification effect of carbon black N234 by using the synergistic bi-component modifier SF/SE（medium molecular weight，amphipathic，nonionic borate ester） system was better than that of single- component modifier SF，and the dispersibility of modified carbon black N234 in the matrix was improved. Compared with the compound with the unmodified carbon black N234，the Mooney viscosity of the compound with modified carbon black N234 was reduced greatly，the tensile properties，the tear resistance， wear resistance and aging resistance were improved，the compression fatigue heat build-up decreased. |
