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 。
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.
