| 研究液相充油（同时混入补强填料白炭黑）对官能化溶聚丁苯橡胶（SSBR）胶料性能的影响。结果表明：与未充油官能化SSBR（以下简称SSBR）混炼胶和硫化胶相比，充油（充芳烃油和充环烷油）SSBR混炼胶的门尼粘度显著减小，加工性能显著改善；充油SSBR混炼胶和硫化胶的Payne效应减弱，即白炭黑的分散性提高；充油SSBR硫化胶的邵尔A型硬度减小，拉伸强度变化不大，撕裂强度增大，压缩疲劳温升降低，耐磨性能提高。与充芳烃油SSBR混炼胶和硫化胶相比，充环烷油的混炼胶的门尼粘度减小，硫化胶的300%定伸应力增大，压缩疲劳温升降低，耐磨性能提高，60 ℃时的损耗因子减小10%，滚动阻力降低。 |
| 英文摘要: |
| The influence of liquid phase oil-extension（with the simultaneous incorporation of reinforcing filler silica） on the properties of functionalized solution-polymerized styrene-butadiene rubber（SSBR） compounds was investigated.The results showed that compared to unextended functionalized SSBR（hereinafter referred to as SSBR） compound and vulcanizate，the Mooney viscosities of oil-extended（aromatic oil-extended and naphthenic oil-extended） SSBR compounds significantly decreased，and the processabilities were significantly improved.The Payne effects of oil-extended SSBR compounds and vulcanizates were weakened，indicating improved silica dispersion.The Shore A hardnesses of oil-extended SSBR vulcanizates decreased，tensile strengths changed little，tear strengths increased，compression fatigue temperature rise was reduced，and wear resistance was improved.Compared to aromatic oil-extended SSBR compound and vulcanizate，the naphthenic oil-extended compound exhibited a reduced Mooney viscosity，the vulcanizate displayed a increased 300% modulus，reduced compression fatigue temperature rise，improved wear resistance，10% decrease in loss factor at 60 ℃，and reduced rolling resistance. |
