摘　　要：选用非离子型表面活性剂Span-80和Tween-40为乳化剂,以环己烷为油相,采用反相乳化法,制备具有抗紫外效果的高分散纳米乳液。通过测定乳液的平均粒径和稳定性能,研究了乳化剂的组成,分散相体积分数,乳化剂用量和乳化温度等因素对乳液体系稳定性的影响,探索该乳液制备的最佳条件。结果表明,以Span80和Tween40按质量比1∶1作为乳化剂,乳化剂用量为4%,分散相体积分数10%,乳化温度为55℃,10 000 r/min下乳化10 min,可获得平均粒径在150 nm以下的乳液,且具有较好的稳定性及抗紫外线性能。With the method of emulsion inversion phase(EIP),the O/W type nano-emulsions was prepared using the composite surfactant Span80-Tween40 and by taking cyclohexane as the oil phase. The influences of the emulsifier concentration and composite,volume fraction of disperse phase and the temperature of the prepared emulsions were studied by measuring its droplet size and stability. The results showed that when the mass ratio of Span80 to Tween40 is 1∶ 1,the amount of emulsifier is 4%,the volume fraction of disperse phase is 10%,and control the temperature 55 ℃,emulsifying for 10 min with the rotate speed10 000 r/min. The average diameter of nano-emulsions was less than 150 nm,and it has excellent stability and uvioresistant performance.
