摘　　要：以高门尼黏度丁苯橡胶(SBR)1723基础胶浆和稠环芳烃质量分数低于3.0%的环保型橡胶填充油为原料制备环保型充油SBR,考察了乳化工艺对填充油乳化效果的影响以及所制得的环保型充油SBR的性能。结果表明,在以歧化松香酸钾皂为乳化剂、先将乳化剂加入填充油中搅拌一段时间后再加入水的油乳化方式、油乳化温度为70℃、填充油/水/乳化剂(质量比)为100/200/2以及凝聚时搅拌转速为163 r/min、凝聚温度为65～70℃的条件下,所得产品的各项性能指标满足产品标准的要求。Environmental-friendly oil-extended styrene-butadiene rubber（SBR） was prepared with high Mooney viscosity SBR 1723 latex and environmental-friendly extending oil in which the mass fraction of polycyclic aromatic hydrocarbons was less than 3.0% as materials,and the influences of emulsification process on emulsification effect of extending oil and properties of environmental-frendly oil-extended SBR were investigated.The results showed that the properties of the obtained environmental-friendly oil-extended SBR met the requirements of technical indicators under the conditions of emulsifying temperature 70 ℃,extending oil/water/emulsifier（mass ratio） 100/200/2,stirring rate of agglomeration 163 r/min,agglomerating temperature 65-70 ℃ when the emulsification process was used,by which the emulsifier disproportionated rosin acid soap was added into extending oil and stirred first and then the water was added.
