PHYSICO-MECHANICAL PROPERTIES OF RUBBER SEED SHELL CARBON – FILLED NATURAL RUBBER COMPOUNDS

ABSTRACT

Samples of rubber seed shells were carbonized at varying temperatures (100,
200, 300, 400, 500, 600, 700 and 800 °C) for three hours each and sieved
through a 150 µm screen. The portion of the rubber seed shell carbon that
passed through the screen was characterized in terms of loss on ignition, surface
area, moisture content, pH, bulk density, and metal content and used in
compounding natural rubber. The characterization shows that the pH, conductivity,
loss on ignition and the surface area increases with the increases of the
heating temperature, unlike the bulk density which decreases. The compound
mixes were cured using the efficient vulcanization system. Cure characteristics
of compounds and physico-mechanical properties of the vulcanisates were
measured as a function of filler loading along with that of N330 carbon-black
filled natural rubbers. The results showed that the cure times, scorch times and
the torque gradually increased, with increasing the filler content for rubber
seed shell carbon-filled natural rubber, with the filler obtained at carbonizing
temperature of 600 °C tending to show optimum cure indices. The physicomechanical
properties of the vulcanisates increase with filler loading. The reinforcing
potential of the carbonized rubber seed shell carbon was found to increase
markedly for the filler obtained at the temperature range of 500-600 °C
and then decreases with further increase in temperature
