| Abstract: | The cure characteristics and mechanical properties of short nylon fiber- styrene
/whole tyre reclaim (SBR/WTR) composites with and without
an interfacial bonding agent based on 4,4 diphenyl methane diisocyanate and
polyethylene glycol (MDI/PEG) have been studied. An 80:40 blend of SBR/
WTR reinforced with 20 phr of short nylon fiber has been selected and the MDI/
PEG ratio has been changed from 0.67:1 to 2:1. The minimum and maximum
torques increased with isocyanate concentration. The scorch time and cure time
showed an initial reduction. The cure rate showed an initial improvement.
Tensile strength, tear strength and abrasion resistance increased with MDI/PEG
ratio, these values were higher in longitudinal direction. Resilience and
compression set increased with isocyanate concentration. |
