利用高速搅拌和超声乳化法,制备了液体石蜡乳液。研究了表面活性剂的组成、用量和温度等因素对乳液性能的影响。结果表明:添加0.5%的油酸钠和十六烷基三甲基溴化铵混合表面活性剂制备的乳液为O/W型,乳液久置不分层,稀释分散性为一级,无漂油现象,稳定性良好。乳液的表面张力平均值为24.50mN/m,D50平均粒径为1.56μm。
Liquid paraffin wax emulsion was prepared by high-speed stirring and ultrasonic wave.The effects of surfactant content,HLB value and temperature on the property of emulsion were studied.The results showed that O/W emulsion was obtained by adding 0.5mass% compound surfactants,which included 50mol% sodium oleate and 50mol% cetyl trimethyl ammonium bromide.The emulsion was stable for long time.The dispersibility and dilution of emulsion was first-grade.Floating oil was not found.The surface tension and D50 particle size of emulsion were 24.50mN/m and 1.56μm,respectively.
