Abstract:

The application of nonionic surfactant and nonionic surfactant formulation in the silicone oil emulsion was studied. Uniform design and optimization soft-ware were used in design of  the emulsifier formula and optimization of the experiment results. The synergic effects between the surfactants were investigated. The optimum [KG*4]formula [KG*4]was got. The nonionic surfactant [KG*4]and [KG*4]nonionic [KG*4]surfactant [KG*4]in [KG*4]the [KG*4]formula [KG*4]have [KG*4]synergic [KG*4]effect. [KG*4]The [KG*4]optimum [KG*4]formula [KG*4]of  [KG*4]the [KG*2/3]mass [KG*2/3]ratio [KG*4]are  w（X1）30.14%, w（X2）23.69%, w（X3）22.45%, w（X4）13.05%, w（X5）10.67%. The silicone oil emulsion is prepared and not stratified at the 3 000 r/min by centrifugating 30 min.

摘要： 对非离子表面活性剂在硅油乳液制备中的应用进行了研究。采用均匀设计与调优软件进行乳化剂配方的设计和实验结果的优化, 考察了表面活性剂间的相互作用, 得到了最佳配方。结果表明, 配方中的表面活性剂间均有强烈的协同作用, 最佳配方:w(X 1)=30 .14%, w(X 2)=23 .69%, w(X 3)=22.45%, w(X 4)=13.05 %, w (X 5)=10.67 %。制备的硅油乳液稳定性好, 在3 000 r/min 的转速下离心30 min 不分层、不漂油。
