烷基酚聚氧乙烯醚类表面活性剂具有良好的乳化作用,是硅油乳化剂的常用原料,但是其生产过程中副产物和它的最终代谢产物都有很强的毒性,不符合欧盟规定的环保型表面活性剂的标准,因此,研究了不含烷基酚聚氧乙烯醚的非离子表面活性剂复配体系的硅油乳化剂.采用均匀设计与调优软件进行乳化剂配方设计与优化,在乳化剂质量分数为7% 的条件下,选用不同种类的非离子表面活性剂对乳化剂进行复配,确定各因素的取值范围,在此范围内设置适当的水平,根据因素数、水平数来选择合适的均匀设计表进行因素水平数据排布,对均匀设计表中的实验点进行实验,对所得的实验数据进行回归分析,建立回归模型,对回归方程得到优化的实验点进行实验验证,考察了表面活性剂之间的协同作用以及对乳化硅油稳定性的影响,得到了最佳的不含烷基酚聚氧乙烯醚的环保型非离子硅油乳化剂配方.%Alkylphenol polyoxyethylene ether surfactants have good emulsifying properties and are common raw materials for silicone oil emulsifiers ,however ,the by‐products and their final metabolites in the production process are highly toxic and can not meet the EU requirements on environmentally friendly surfactants .The non‐ionic surfactant complex system without alkylphenol polyoxyethylene ether as silicone oil emulsifier was studied in this paper .The experiments were designed and optimized with uniform design software.Under the condition that the quality fraction of emulsifier was 7%,different kinds of non‐ionic surfactants were used as emulsifiers to determine the value range of each factor and set an appropriate level within this range.According to factor number and level number ,the appropriate uniform design table was selected for factor horizontal data arrangement ,and the experimental points in the uniform design table were tested .The obtained experimental data were analyzed by regression analysis ,the regression model was established ,and the optimized experimental points of the regression equation were verified experimentally .The synergistic effect of surfactants and the effect on the stability of emulsified silicone oil were investigated .The optimal environmentally friendly non‐ionic silicone oil emulsifier without alkylphenol polyoxyethylene was obtained.
