TextPublication details: Proceedings of IRRDB Symposium 1999, Hainan, Peoples Republic of China. pp.493-498. 1999Subject(s): Summary: The thermal degradation of clay-rubber masterbatch prepared from the clays modified with the polymer coating agents, silicane and titanate coupling agents, were studied by thermogravimetry (TG) and differential thermal analysis (DTA). The results indicate that, in the nitrogen, the thermal degradation temperatures of masterbatch reduced owning to the reactions of the modifying agents with the hydrocarbon of natural rubber. The thermooxidative stabilities of masterbatch from the modified clay in the air were increased, because the catalytic action of metal ions in clay on masterbatch had been inhibited by the polymer coating agents and the silicane coupling agents.
