摘要: 石蜡微乳液是由58#石蜡、离子和非离子表面活性剂制备而成。影响石蜡微乳液粒径的因素有乳化剂用量、乳化温度、乳化时间、搅拌速度、pH值和助表面活性剂。实验结果表明:乳化温度在75-85℃时对石蜡微乳液的粒径影响不大;而其它因素对石蜡微乳液的粒径影响较大。制备石蜡微乳液的最佳工艺条件为:w(乳化剂)=6%,乳化温度为80℃,乳化时间为40min,pH为8,搅拌速度约600r/min,助表面活性剂为正戊醇。在此条件下,可以制备粒径为97nm、半透明的石蜡微乳液。

Abstract: The paraffin wax microemulsion was prepared with 58# paraffin wax, nonionic surfactant and anionic surfactant. The effects of manufacturing parameters on the particle diameter of paraffin wax microemulsion were the quantity of the emulsifier, the temperature and time of emulsification, stir speed, pH and accessory ingredient (cosurfactant). The results showed that the temperature of emulsification had little effect on the particle size of paraffin wax microemulsion in the range of 75-85℃. The other manufacturing parameters all had a great effect on the particle size of paraffin wax microemulsion. Optimum conditions were as follows: w(emulsifier) was 6%, emulsification temperature was 80℃, emulsification time was 40min, pH was about 8, stir speed was 600r/min and the cosurfactant was the n-amyl alcohol. Under this condition, we can prepare the translucent and baby blue paraffin wax emulsion which particle size was 97 nm.
