Study on Dynamic Fatigue Properties of Solution-Polymerized Styrene Butadiene Rubber T2000R

Abstract

Dynamic fatigue properties of solution-polymerized styrene butadiene rubber with the trade name T2000R were studied. The influence of different cure systems, reinforcing agents, anti-degradants, and plasticizers on the flex-cracking property of T2000R vulcanizates was investigated. The results showed that T2000R cured with an effective vulcanization system had relatively high fatigue life. Vulcanizate filled with carbon black N330 with a load of 15 phr had better fatigue resistance. Then, a combination of aging resisters 6PPD and RD prolonged the fatigue life of T2000R significantly. T2000R extended with aromatic oil had a fatigue life higher than those extended with mineral oil, naphthenic oil, and courmarone. Among all the factors, aging resister and the load of carbon black contributed more to the flex-cracking properties of T2000R than other additives.
