The Effect of Surface Treated Nano Montmorillonite as a Filler on the Cure Characteristics of NR/SBR Compound

In this work, nano montmorillonite (MMT) was surface treated by polypropylene glycol (PPG). MMT and surface treated nano montmorillonite (STMMT) were characterized by using Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM). These two materials were used as fillers in the compounds based on natural rubber (NR) and styrene butadiene rubber (SBR). The cure characteristics of the compounds were studied. Results were shown a considerable decrease in T’c90 whereas cure rate index was increased. The reinforcing effect of the filler was increased too. It was caused by better hydrophobicity and dispersion of the filler in rubber matrix.
