Blends
of Acrylonitrile rubber with Maleic anhydride grafted Whole Tire Reclaim
WTR (MA-g-WTR) are to be prepared and the cure and mechanical
properties are to be studied with respect to reclaim content. Control
compounds containing unmodified WTR will also be prepared for
comparison.
Grafting will be confirmed by IR studies. Blends containing grafted WTR showed higher minimum torque and (max-min) torque. They also showed longer cure time, scorch time and lower cure rate. Grafting of the WTR with maleicanhydride also resulted in the improved tensile strength, abrasion resistance, compression set and resilience. However, the heat buildup under dynamic loading was marginally higher for the blends containing grafted reclaimed Rubber studied before.
