摘要
在中试装置上合成相对分子质量分布较宽的充油S SBR ,考察不同环烷油和芳烃油填充量的充油S SBR的流变性能和混炼行为。结果表明 ,增大油的填充量能提高充油S SBR的流动性能 ,充芳烃油S SBR相对于充环烷油的S SBR对温度更敏感 ,宽相对分子质量分布的充环烷油S SBR的混炼性能优于S SBR12 0 4及E SBR1778,宽相对分子质量分布的充芳烃油S SBR的混炼性能优于S SBR12 0 4,Solprene 3 80和E SBR1712。
The various oil-extended S-SBRs(OESSBR) with broader molecular weight distribution were synthesized on a pilot plant and the rheological properties and mixing behaviour of S-SBRs extended with different contents of naphthenic oil or aromatic oil were investigated.The results showed that the flowability of OESSBR improved by increassing the content of oil;the S-SBR extended with aromatic oil was more sensitive to the temperature than that extended with naphthenic oil;the mixing behaviour of naphthenic oil-extended S-SBR with broader MW was superior to those of S-SBR1204 or E-SBR1778;and the mixing behaviour of aromatic oil-extended S-SBR was superior to those of S-SBR1204,Solprene 380 and E-SBR1712.
