摘要
研究4种牌号溶聚丁苯橡胶(SSBR)在高性能轮胎胎面胶中的应用。结果表明:SSBR5251H胶料的门尼粘度较小,加工性能较好,回弹值最大,耐磨性能最好,滚动阻力最小;与SSBR5251H胶料相比,SSBR5360H和SSBR5271H胶料的300%定伸应力增大,回弹值减小,耐磨性能下降,SSBR5360H胶料具有最佳的抗湿滑性能,SSBR5271H胶料具有良好的抗湿滑性能和较低的滚动阻力;SSBR6440H胶料的门尼粘度最大,门尼焦烧时间最短,拉伸强度和撕裂强度最大,耐磨性能良好,与SSBR5271H胶料相比,其玻璃化温度相同,0℃时的损耗因子减小,60℃时的损耗因子和压缩疲劳温升增大,具有较高的滚动阻力和生热。
The application of four brands of solution polymerized styrene butadiene rubber(SSBR)in the tread compound of high performance tire was investigated.The results showed that,the Mooney viscosity of the SSBR5251H compound was low,the processability was good,the rebound value was the largest,the wear resistance was the best,and the rolling resistance was the lowest.Compared with SSBR5251H compound,the modulus at 300%elongation of the SSBR5360H and SSBR5271H compound was higher,the rebound value and wear resistance was lower.SSBR5360H compound had the best wet skid resistance,and SSBR5271H compound had good wet skid resistance and low rolling resistance.The Mooney viscosity of the SSBR6440H compound was the highest,the Mooney scorch time was the shortest,the tensile strength and tear strength were the highest,and the wear resistance was good.Compared with SSBR5271H compound,the glass transition temperature of the SSBR6440H compound was the same,the loss factor at 0℃was lower,the loss factor at 60℃and compression fatigue temperature rise was higher,indicating that it possessed higher rolling resistance and heat build-up.
