中文摘要:
      目的 研究乳化剂体系、乳化剂含量和乳化剂复配比对乳液外观、粒径、吸水率、凝胶率的影响。方法 以甲基丙烯酸甲酯(MMA)和甲基丙烯酸(MAA)为硬单体,丙烯酸异辛酯(EHA)为软单体,以过硫酸铵(APS)为引发剂,采用半连续种子乳液聚合方法制得丙烯酸乳液。结果 将阴离子乳化剂十二烷基硫酸钠(SDS)与非离子乳化剂脂肪醇聚氧乙烯醚(AEO-9)复配使用,质量分数为3%,且SDS与AEO-9的复配质量比为2∶1时,2种乳化剂的协同作用效果最佳,制得丙烯酸乳液的各项性能更优。结论 在相同的实验条件下,使用复合乳化剂制得的丙烯酸乳液性能更稳定。
英文摘要:
      The work aims to study the effects of emulsifier system, emulsifier content and emulsifier ratio on the appearance, particle size, water absorption and gelatin of emulsions. With methyl methacrylate (MMA) and methacrylic acid (MAA) as hard monomers, ethyl hexyl acrylate (EHA) as soft monomer, and ammonium persulfate (APS) as initiator, the acrylic emulsion was prepared by seeded semi-continuous emulsion polymerization. The synergistic effect of 2 emulsifiers was the best and the properties of the acrylic emulsion prepared were better when the anionic emulsifier sodium dodecyl sulfate (SDS) and the nonionic emulsifier pri-mary alcobol ethoxylate (AEO-9) were used together with the mass fraction of 3% and the mass ratio of SDS/AEO-9 was 2∶1. The acrylic emulsion prepared by compound emulsifiers is more stable under the same experimental conditions.
