Effect of Carbon Black Types on Curing Behavior of Natural Rubber

الوصف الكامل (Full Abstract)

This research extensively investigated to improve the processing characteristics of natural rubber NR by insertion
various types of carbon black. The average of nitrogen surface area (34 for N660, 76 for N330, 77for N326, and
91for N375) m2/g and range of particles size (26 -63)nm high abrasive furnace. The curing kinetics was
determined using the rheometer with an oscillating disk, in which the network formation process is registered by
the torque variation during time. The vulcanization was obtained in a hydraulic press at 185 °C. OSD rheometer
results clearly indicate that optimum cure time, scorch time and cure rate (100/t90-ts2) are exponentially
decreases with increasing in particles surface area. However, increase in Max., Min. torque of OSD rheometer,
reversion period time of cure characteristics and Mooney viscosity ML (1+4) at 100C° with increasing the surface
area. This result clearly indicates the improvement of curing characteristics.
