Abstract: Ground silica filled natural rubber (NR) could be prepared by acid coagulation of
ground silica slurry with natural rubber latex (NRL). The ground silica with average particle
size 18.9 ± 2.5 nm were prepared from conventional silica by using wet grinding process in
stirred bead mill machine. This process can comminute the particle size of silica from micron to
nano range with good dispersion and particle size distribution (PSD). Styrene maleic anhydride
copolymer derivative (SMA) was selected as dispersing agent of ground silica filled NR. The
presence of SMA can increase silica content in NR matrix and decrease acid character of silica
particle via ionic interaction with silanol group. SMA treated ground silica reduced trapped cure
accelerator resulting in faster sulfur crosslinking reaction. Experimental was also designed to
study the influence of SMA on mechanical properties of NR vulcanizates.
