| 中文摘要: |
| 研究硅格粉在全钢子午线轮胎基部胶中的应用。结果表明：与生产配方胶料相比，加入硅格粉的试验配方胶料的门尼焦烧时间变化不大，Fmax－FL减小，表明硅格粉与NR形成胶料交联密度略差于白炭黑胶料；试验配方硫化胶的50%和100%定伸应力略有下降；300%定伸应力、拉伸强度和撕裂强度明显下降；试验配方硫化胶60 ℃时的损耗因子显著降低，可降低生热；试验轮胎的耐久性能提升，滚动阻力下降。 |
| 英文摘要: |
| The application of silica lattice powder in base compound of all-steel radial tire was studied. The results showed that，compared with the production formula compound，the Mooney scorch time of the test formula compound using silica lattice powder changed little and the Fmax－FL decreased，indicating that the crosslinking density of the silica gel powder and NR compound was slightly worsed than that of the silica filled NR compound. Compared with the production formula vulcanizate，the modulus at 50% and 100%
elongation of the test formula vulcanizate decreased less. The modulus at 300% elongation，tensile strength
and tear strength decreased significantly. The loss factor of the test formula vulcanizate at 60 ℃ decreased
significantly，indicating that its heat build-up was low. The durability of the finished tires of the test formula
was improved and the rolling resistance was reduced. |
