摘　　要：研究液体橡胶液体聚丁二烯(LPBD)替代芳烃油对全钢载重子午线轮胎胎圈护胶(顺丁橡胶/天然橡胶并用胶)的硫化特性、加工性能、物理性能、生热性能和动态力学性能的影响。结果表明:LPBD等量替代芳烃油后,胶料的t_(10)略有延长,t_(90)略有缩短,LPBD的增塑作用小于芳烃油;硫化胶的硬度、拉伸性能和抗撕裂性能提高,压缩温升降低,LPBD Activ-1000硫化胶的动态力学性能较好,LPBD Activ-50硫化胶与芳烃油硫化胶的动态力学性能相近。In this study,the liquid rubber liquid polybutadiene(LPBD)was used to replace the aromatic oils in the bead filler compound(BR/NR blend)of truck and bus radial tire,and the effects of LPBD on the vulcanization characteristics,processability,physical properties,heat generation performance and dynamic mechanical properties of the bead filler compound were studied.The results showed that the t_(10) of the compound was slightly prolonged and the t_(90) was slightly shortened when the aromatic oil was replaced by LPBD in the same amount.The plasticizing effect of LPBD was less than that of aromatic oil.However,the hardness,tensile properties and tear resistance of the vulcanizate with LPBD increased,while the compression temperature rise decreased.It was found that the dynamic mechanical properties of the vulcanizate with LPBD Activ-1000 were better,and the dynamic mechanical properties of the vulcanizate with LPBD Activ-50 were equivalent to those with aromatic oil.
