摘要/Abstract

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。

Abstract: 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 131.1nm, 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.
