响应曲面法优化水包油型天然松香乳液的制备
|
摘要
以天然马尾松松香为原料、ONIST APS-350为乳化剂采用常压转相法制备水包油(O/W)型天然松香乳液。考察了乳化剂用量、初始乳化温度、油水比(松香和水质量比,下同)与搅拌速度对O/W型天然松香乳液粒径分布的影响,并通过响应曲面法(RSM)对制备乳液的工艺参数进行模拟与优化。结果表明:制备O/W型天然松香乳液的最佳工艺条件为搅拌速度500 r/min、乳化剂用量9.95%、初始乳化温度112℃、油水比10∶31,所得乳液平均粒径为131.1 nm,乳液离心稳定,静置3个月不分层,通过TEM表征发现,这种天然松香乳液颗粒具有核壳结构,其粒径大小与粒径仪测试结果一致。
Oil in water(O/W) natural rosin emulsion was prepared by the method of normal pressure phase inversion emulsification with natural rosin as raw material and ONIST APS-350 as emulsifter. The influences of emulsifier dosage,initial emulsification temperature,oil-water ratio(the mass ratio of rosin and water) and stirring speed on the particle size distribution of O/W natural rosin emulsion were investigated,and then the response surface method(RSM) was used to simulate and optimize the process parameters. The results showed that the optimum parameters were determined as follows: stirring speed 500 r/min,emulsifier dosage 9. 95 %,temperature 112 ℃,and oil-water ratio 10 ∶31. Under these conditions,the average particle size of emulsion was 131. 1 nm,the emulsion was not stratified by centrifugal force and not stratified for 3 months. The results of TEM showed that the particles had core-shell structure,and the particle size was consistent with the experimental value.
