摘　　要：采用剂在油中法乳化工艺,以58#全精炼石蜡、水和Span80-Tween80复合表面活性剂作为原料制备了石蜡乳液。实验优化了乳化石蜡的配比,考察了乳化条件对石蜡乳液稳定性及分散性的影响。结果表明,采用混料实验确定各组分最优掺量为:乳化剂掺量9.24%,水掺量为65.76%,石蜡掺量为25%。采用单因素实验确定较佳乳化条件为:HLB=10,温度80℃,乳化时间40 min,搅拌速率1000 r/min。In view of the complicated process of preparing paraffin emulsion,a variety of co-emulsifiers are added during the preparation process,and physical or chemical methods were used to treat paraffin wax.The prepared emulsion has insufficient stability and poor dispersion.This study proposes a new preparation method to solve the above problems.Span 80 and Tween 80 are mixured as the composite surfactant in the emulsification process.Paraffin emulsion was prepared using 58#fully refined paraffin,water,and the composite surfactants as raw materials.The effects of emulsifier content,paraffin content,emulsifying water content,hydrophilic-lipophilic balance(HLB value),emulsification temperature,emulsification time and stirring speed on the stability and dispersibility of paraffin emulsions were all studied.The optimal dosage of each component were determined by mixing experiment:the emulsifier content is 9.24%,the water content is 65.76%,and the paraffin wax content is 25%.The best emulsification conditions were determined use single factor experiment:the HLB value is 10,the temperature is 80℃,the emulsification time is 40 min,and the stirring speed is 1000 r/min.
