| 研究经双驱动同步齿轮泵式滤胶机滤网过滤的溶聚丁苯橡胶（SSBR）/顺丁橡胶（BR）并用胶的性能变化以及滤网孔径对SSBR/BR并用胶性能的影响。结果表明：经滤胶机滤网过滤后，SSBR/BR并用胶的硫化特性和物理性能改善；随着滤网孔径的减小，SSBR/BR并用胶的邵尔A型硬度、100%定伸应力、300%定伸应力、拉伸强度、拉断伸长率和撕裂强度都呈先增大后减小的趋势，Payne效应越来越弱；滤网孔径为75 μm时，SSBR/BR并用胶的拉伸强度和撕裂强度最大，分别比未过滤的SSBR/BR并用胶增大27.5%和33.3%，耐屈挠性能最好，损耗因子（tanδ）峰值最大，玻璃化温度最高，60 ℃时的tanδ最小，滚动阻力最低。 |
| 英文摘要: |
| The property change of solution polymerized styrene butadiene rubber（SSBR）/butadiene
rubber（BR） blend filtered through a double drive synchronous gear pump rubber filter and the effect of the
screen aperture on the properties of SBR/BR blend were studied. The results showed that，the vulcanization
characteristics and physical properties of the SSBR/BR blend were improved after the screen filtration of the
rubber filter. With the decrease of the screen aperture，the shore A hardness，tensile stress at 100% elongation，
tensile stress at 300% elongation，tensile strength，elongation at break and tear strength of the filtered SSBR/
BR blend increased first and then decreased，and the Payne effect became weaker. When the screen aperture
was 75 μm，the tensile strength and tear strength of the filtered SSBR/BR blend were the largest，which were
27. 5% and 33. 3% larger than those of the unfiltered SSBR/BR blend，respectively，the flexure resistance
was best，the tanδ peak value was the largest，the glass transition temperature was the highest，the tanδ at 60
℃ was the smallest，and the rolling resistance was the lowest. |
