摘　　要：采用破乳化试验,探讨了6种破乳化添加剂对汽轮机油破乳化性能的影响。在初步筛选的基础上,通过复配实验寻找出具有协同效应的新破乳化剂组合。结果表明:A、B、E和F等4种破乳化添加剂对汽轮机油破乳化效果较好,并且A分别与B、E及F等3种破乳剂复配皆有协同作用,尤其是A与E复配,其破乳化性能优于各自单体,它对油品的闪点、黏度等理化性能无不良影响,反而使油品的某些理化性能得以改善,如酸值下降等。正交实验确定了A与E复配的最佳工艺条件为:A与E添加量分别为0.10%、0.030%(重量百分比),搅拌时间为10min,破乳化温度为50℃。Through emulsion breaking experiments, effects on the break emulsion properties of turbine oil by six emulsifying agents added are discussed. Based upon initial screening experiments and match tests, four break emulsion of additives, such as A, B, E and F, have better performance of emulsion breaking. And the three new binary compound additives （A ＆B, A ＆E,and A ＆ F）have synergy,especially the A ＆ E compound with its break emulsion performance is superior to each of their own monomer , not only the numerical value of flash point, viscosity are not changed greatly, but also the total acid number is decreasing after the combined. Finally, the orthogonal experiment results show that the best technological of the A ＆ E compound is 0.10% A ＋ 0.030% E（ wt% ）, ten minutes churning, and 50℃.
