中文摘要: |
采用NR塑性保持率的测定方法、橡胶热空气老化试验方法、热分析技术及扫描电镜分析等,研究了促进剂TMTD对粘土填充NR胶料抗热氧老化性能的影响。试验结果表明,在制备粘土填充NR胶料时,采用半有效硫化体系或有效硫化体系硫化,加入1.5或3.0份促进剂TMTD,可以获得很好的抗热氧老化性能。 |
英文摘要: |
The effect of TMTD on the heat and oxygen aging of clay-filled NR compound was investigated by using determination for plasticity retention of NR, test method of hot air aging, thermal analysis and SEM.The results showed that the excellent anti-heat and oxygen aging property could be obtained when the clay-filled NR compound was cured by semi-effective or effective curing system with 1.5 phr or 3.0 phr of TMTD. |
