摘要: 反相乳液聚合是近年发展较快的一种聚合方法,具有聚合速率高、高度分散、大小均一等突出优点。以Tween60与Span80为复合乳化剂制备了W/O型反相乳液体系。考察了乳化转速、时间、乳化剂的HLB值和质量分数以及油水体积比对乳液类型和稳定性的影响。由实验确定了反相乳液的最优条件:转速为14 000 r/min,乳化时间35 min,乳化剂HLB值为5.0,油水体积比为1∶1,乳化剂质量分数为4%时,可形成较为稳定的W/O型乳液。同时,结合实验结果对部分稳定机理进行了分析。

Abstract: Inverse emulsion polymerization is developing rapidly in recent years. The polymerization method has the following advantages, such as high polymerization rate, a highly decentralized and uniform size of polymerization particles. The water-oil inverse emulsion was prepared with the compounds of Span80 and Tween60 as emulsifier. It was investigated by way of electric conductivity that the types and stability of the inverse emulsion was affected by many kinds of factors such as emulsification time, rotate speed, HLB value and emulsifier concentration, ratio of oil to water, and the optimum conditions for forming stable water-oil inverse emulsion were attained as the emulsification time about 35 [KG*4]minutes, the [KG*4]rotate [KG*4]speed [KG*4]on 14 000 r/min, HLB value of mixed emulsifier at 5.0, the mass ratio of oil to water in 1∶1, and the content of the mixed emulsifier at 4%. Based on the experimental results, some aspects of the stability mechanism were explained.
