摘　　要：以精制褐煤蜡为油相,采用相反转法制得蜡乳液。通过单因素和正交试验法,以乳液粒径为判断标准,分析了乳化剂比例、蜡比例、搅拌转速和搅拌时间对蜡乳液稳定性的影响,优化了蜡乳液的制备工艺条件,在此基础上,研究了蜂蜡的加入量对乳液粒径及稳定性的影响,得到了优化的精制褐煤蜡/蜂蜡复合蜡乳液的配方组成和制备工艺条件,并测试了复合蜡乳液的抑菌性能和应用性能。结果表明,对蜡乳液粒径影响从大到小的顺序为:乳化剂比例、搅拌转速、蜡的比例和搅拌时间;优化的制备工艺条件:椰子油脂肪酸二乙醇酰胺质量分数为6.30%、吐温60为0.75%、司盘60为2.95%、精制褐煤蜡为7.00%、蜂蜡为3.00%、水为80.00%、搅拌转速为1500 r/min、搅拌时间为10 min;优化条件下得到的乳液粒径为650.2 nm;3.00%蜂蜡的加入可以大幅度降低乳液的粒径(352.5 nm),且分布更均一,大大提高了乳液的稳定性;自制蜡乳液对大肠杆菌和金黄色葡萄球菌均具有较好的抑菌效果;将蜡乳液应用于皮革的涂饰中,能大幅度提高皮革的变色效果、光亮度和手感。The wax emulsion was prepared by phase inversion method using refined montan wax as oil phase.Both single-factor and orthogonal experimental methods were used,in which emulsion particle size was used as a criterion for judgment.The effects of emulsifier dosage,wax ratio,stirring speed and stirring time on the stability of wax emulsion were studied.The process conditions for preparation of wax emulsions were optimized.Furthermore,the effects of incorporation of beeswax on the stability and particle size of the emulsion were also studied.Then,a composite emulsion of refined montan wax/beeswax with optimal formulation and preparation procedure was obtained.The antibacterial and application properties of the composite wax emulsion were also tested.The results showed that,the influencing factors on the particle size of the wax emulsion was in the descending order of emulsifier dosage>stirring speed>wax ratio>stirring time.The optimized preparation conditions were:The mass fraction of coconut oil fatty acid diethanolamide of 6.30%,Tween60 of 0.75%,Span60 of 2.95%,refined montan wax of 7.00%,beeswax of 3.00%,water of 80.00%,stirring speed of 1500 r/min,and stirring time of 10 min.The particle size of the emulsion prepared under optimized conditions was 650.2 nm.It was confirmed that the addition of 3.00%beeswax could drastically reduce the particle size of the emulsion,and the particle size distribution became more uniform,which greatly improved the stability of the emulsion.This wax emulsion had good bacteriostatic effects on both Escherichia coli and Staphylococcus aureus.The wax emulsion was applied in leather finishing,indicative of significant improvement in the color change effect,brightness,and feel of the leather.
