摘　　要：以60^(#)费托蜡为原料,利用剂在油中法,以Span、Tween系列作为主乳化剂复配,探究了乳化剂种类、乳化温度、搅拌速率、滴加速率和乳化剂含量对所制备的费托蜡乳液性能的影响。结果表明,在乳化温度为80℃、搅拌速率为900 r/min、水相滴加速度为1 mL/min和乳化时间为30 min的条件下,制备出高稳定性和高分散性的亚微级费托蜡乳液,其乳液平均粒径控制在200 nm左右,蜡质量分数为35.71%,黏度在2~5 mPa·s。同时,通过对乳化剂进行适当选择以及助乳化剂的合理掺杂,能在保证乳液其他性能不受较大波动的情况下减少乳化剂的用量。Taking 60^(#) Fischer-Tropsch wax as raw material, Span and Tween series as main emulsifiers, Fischer-Tropsch wax emulsion is prepared via the agent-in-oil method.The influences of the types of emulsifiers, emulsification temperature, stirring rate, dripping speed and emulsifier content on the performance of the prepared emulsion are explored.It is found that a submicron Fischer-Tropsch wax emulsion with high stability and high dispersibility is obtained when emulsification temperature is at 80℃,stirring rate is 900 r·min^(-1),water phase is dropped at a speed of 1 mL·min^(-1)and emulsification spends 30 min.The average particle size of the emulsion is controlled at about 200 nm, the wax content is 35.71%,and the viscosity is 2-5 mPa·s.Through appropriate selection of emulsifiers and reasonable doping of co-emulsifiers, the using amount of emulsifiers can be reduced to a certain extent while ensuring that other properties of the emulsion are not subject to large fluctuations.
