摘要
研究国产天然橡胶(NR,10#标准胶)在低滚动阻力胎面胶中的应用。结果表明:与进口NR(20#标准胶)相比,国产NR的生胶门尼粘度较低,塑性初值和塑性保持率较小,加工性能较好;混炼胶的门尼粘度也较低,硫化返原率稍高;硫化胶的拉断伸长率和撕裂强度稍低,60℃时的损耗因子稍大,耐老化性能略差。
The application of domestic natural rubber(NR,10#standard rubber)in the tread compound with low rolling resistance was studied.The results showed that compared with the imported NR(20#standard rubber),the Mooney viscosity of domestic NR was lower,the initial plastic value and plastic retention were smaller,and the processability was better.The Mooney viscosity of the domestic NR compound was also lower,and the vulcanization recovery rate was slightly higher.The elongation at break and tear strength of the domestic NR vulcanizate were slightly lower,the loss factor at 60℃was slightly larger,and the aging resistance was slightly worse.
