摘　　要：以正辛醇为改性剂,对沉淀白炭黑表面进行改性.探讨改性剂用量、改性温度、改性时间对改性白炭黑粘度的影响.通过数据处理,综合分析得出改性的优化工艺条件为改性温度为120℃,改性时间为2 h,每6.0 g SiO2的改性剂正辛醇用量为50 mL.在该优化条件下,白炭黑的分散性增强,粘度明显降低,表面改性率达到35.72%.The precipitated silica＇s surface was modifed with n-octyl alcohol.The effects of the dosage of modifier,modification temperature and time on modified silica viscosity were discussed.Through data processing and comprehensive analysis,the optimum modification conditions were obtained as follows： modified temperature was 120 ℃,modified time was 2 h,modifier dosage was 50 mL per 6.0 g SiO2.Under this optimized condition,the silica＇s dispersibility enhanced and the viscosity reduced obviously,The modification rate achieved 35.72%.
