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.

溶液聚合丁苯橡胶T2000R的动态疲劳性能研究

研究了商品号为T2000R的溶液聚合丁二苯橡胶的动态疲劳性能。研究了不同的硫化体系、增强剂、抗降解剂和增塑剂对T2000R硫化胶挠裂性能的影响。结果表明，采用有效的硫化体系固化的T2000R具有较高的疲劳寿命。填充炭黑N330的硫化胶在15 phr载荷下具有较好的抗疲劳性能。然后，6PPD和RD组合使用可显著延长T2000R的疲劳寿命。用芳香油延长的T2000R疲劳寿命高于矿物油、环烷油和香豆素延长的T2000R疲劳寿命。其中，抗老化剂和炭黑负载量对T2000R弯曲开裂性能的影响大于其他添加剂。
