苯丙乳液的性能研究

Study on property of styrene acrylic emulsion

以苯乙烯、丙烯酸丁酯、甲基丙烯酸甲酯、丙烯酸为反应单体,过硫酸铵为引发剂,聚乙二醇辛基苯基醚和十二烷基磺酸钠为复合乳化剂,通过连续滴加的乳液聚合工艺制备苯丙乳液。结果表明,当软硬单体配比为1∶1(质量比),SDS∶OP-10=1∶1(质量比),引发剂含量为单体总量的0.3%,可制得较好的乳液。

Using styrene,butyl acrylate, methyl methacrylate and acrylic acid as the reaction monomers, ammonium persulfate as an initiator, sodium dodecyl sulfate and polyethylene glycol phenyl ether as the compound emulsifier to prepare styrene acrylic emulsion through emulsion polymerization craft system which adds by drops continuously. The results shows that the better emulsion can be prepared when the mass ratio of soft to hard monomers is 1：1 ,the mass ratio of SDS to OP-10 is 1：1 ,the mass of initiator is 0.3% of monomers.
