| 中文摘要: |
| 研究不同吸附水含量的白炭黑对溶聚丁苯橡胶（SSBR） /天然橡胶（NR） 并用胶的硫化特性、 物理性能和动态力学性能的影响。 结果表明： 采用密炼机进行两段混炼工艺， 白炭黑的吸附水含量低于9%时， SSBR/NR并用胶的综合性能变化不大； 白炭黑的吸附水含量为9%时， SSBR/NR并用胶的综合性能最佳， 门尼粘度和邵尔A型硬度最小， 60 ℃ 时的损耗因子最小； 白炭黑的吸附水含量高于9%时， SSBR/NR并用胶的综合性能变差， 门尼粘度和邵尔A型硬度增大， 低应变下的定伸应力增大， 60 ℃ 时的损耗因子增大。 |
| 英文摘要: |
| The effects of silica with different adsorbed water content on the vulcanization characteristics，physical properties and dynamic mechanical properties of soluble polymerized styrene-butadiene rubber（ SSBR） /natural rubber（ NR） blends were studied. The results showed that， the internal mixer was used for the two stages mixing process， when the adsorbed water content of silica was lower than 9%， the comprehensive properties of the SSBR/NR blend did not change much. When the adsorbed water content
of silica was 9%， the comprehensive properties of SSBR/NR blend were the best， the Mooney viscosity and
shore A hardness were the smallest， and the loss factor at 60 ℃ was the lowest. When the adsorbed water
content of silica was higher than 9%， the comprehensive properties of the SSBR/NR blend would be worse，
the Mooney viscosity and shore A hardness would increase， the modulus under low strain would increase， and the loss factor at 60 ℃ would increase. |
