环保型塑解剂RWS-3000在载重斜交轮胎基部胶中的应用

Application of Environment-friendly Peptizer RWS-3000 in Base Compound of Truck Bias Tire

研究环保型塑解剂RWS-3000在载重斜交轮胎基部胶中的应用。结果表明:在基部胶中加入塑解剂RWS-3000,可明显降低胶料的门尼粘度,对胶料的硫化特性影响不大,硫化胶的物理性能和耐老化性能下降,滞后损失增大;塑解剂RWS-3000对天然橡胶的塑炼效果与塑解剂SJ-103相当,其最佳用量为0.3份,可减少环境污染。

The application of environment-friendly peptizer RWS-3000 in the base compound of truck bias tire was investigated. The results showed that, by adding peptizer RWS-3000 in the base compound, the Mooney viscosity of the compound decreased significantly, the curing behavior of the compound changed little,the physical properties and aging property of the vulcanizates decreased, and the hysteresis loss increased. The mastication efficiency of peptizer RWS-3000 on natural rubber was similar to peptizer SJ-103. The recommended addition level of peptizer RWS-3000 was 0. 3 phr,and en- vironmental pollution could be reduced.
