摘要
研究填充重环烷油的SBR1762的基本性能,并与SBR1723进行对比。结果表明,SBR1762与SBR1723的理化性能、相对分子质量及其分布水平无明显差异,加工性能相近。与SBR1723胶料相比,SBR1762胶料的硫化速度较慢,硫化胶的300%定伸应力和拉伸强度较大,耐热空气老化性能较差,损耗因子较小,玻璃化温度略高,磨耗性能较好,其它物理性能基本相当。
The properties of heavy naphenic oil filled SBR1762 were investigated and compared to those of SBR1723.The results showed that,the difference of physico-chemical properties,molecular weight and its distribution level,processing property between SBR1762 and SBR1723 was not significant.Compared to those of the SBR1723 compound,the SBR1762 compound possessed slower vulcanization rate,higher modulus at 100% elongation and tensile strength,worse heat aging resistance,lower tanδ value,higher Tg,and better wear resistance,while other physical properties were similar.
