中文摘要: |
研究自制液体异戊橡胶(LIR)对顺丁橡胶(BR)胶料结构与性能的影响,并与石蜡油和进口LIR-50对比。结果表明:LIR能有效改善BR的加工性能,增塑效果与石蜡油接近;与石蜡油相比,LIR几乎完全参与硫化,是一种反应型增塑剂;LIR填充胶料的硫化胶具有较低的抽出率及稳定的物理性能;自制LIR和进口LIR-50使用效果相当。 |
英文摘要: |
The influence of self made liquid isoprene rubber (LIR) on the structure and properties of BR compound was investigated,and compared with paraffin oil and imported LIR 50.The results showed that,LIR could improve the processability of BR,but the plasticating effect of LIR was slightly lower than that of paraffin oil.Compared with paraffin oil,LIR was mostly co crosslinked with BR during vulcanization,so it worked as reactive plasticizer.The vulcanizate plasticized by LIR possessed lower extraction rate and more stable physical properties.The plasticating effect of two kinds of LIR was almost same. |
