Impact of a nanomixture of carbon black and clay on the mechanical properties of a series of irradiated natural rubber/butyl rubber blend

Abstract A series of natural rubber/butyl rubber NR/IIR blend loaded with N660 carbon black (CB) and triethoxy vinyl silane treated clay nanoparticles (TCNPs) were prepared using gamma irradiation in the presence a polyfunctional monomer, trimethylolpropane triacrylate (TMPTA). The effect incorporating different contents CB five parts per hundred (phr) on mechanical properties nanocomposites has been investigated. addition TCNP to CB/rubber composites markedly increase their tensile strength due cross-link density. These results indicated that may be enclosed or trapped occluded structure CB. content ( ? ), elongation at break ? b , %), modulus elasticity E MPa) have incorporation 5 phr into 30 CB-loaded increased value by about 60%. Finally, theoretical models used interpret experimental results.
