|Abstract: ||Heat ageing and thermal stability of a silicone rubber (SR) filled with montmorillonite clay (MMT) was investigated.
Three types of rubber nanocomposites were prepared with hig hly exfoliated Cloisite 30B (SR/C30B), intercalated/exfoliated Cloisite
MMT), and highly intercalated Cloisite 20A (SR/C20A). This study showed that the SR/C30B nanocomposite exhibited
excellent heat resistance in comparison to the other two nanocomposites and neat SR as revealed by higher retention strength. The
thermal stability of the rubber in air was strongly dependent on the clay morphology and increased in the following order: highly
MMT < highly intercalated SR/C20A < highly exfoliated SR/C30B. The thermogravimetric analyses of the SR/C30B nanocomposite showed a substantial increase in the final residue in comparison with the neat SR. This indicated a
major improvement in the thermal stability of the rubber containing the exfoliated clay, which was also supported by the higher activation energy of decomposition measured for the nanocomposite.|
