摘　　要：以十二烷基苯磺酸钠(SDBS)为阴离子型乳化剂、辛烷基苯酚聚氧乙烯醚-10(OP-10)为非离子型乳化剂、烯丙氧基壬基苯氧基丙醇聚氧乙烯醚硫酸铵(SE-10)为可聚合型乳化剂、苯乙烯(St)为硬单体、丙烯酸丁酯(BA)为软单体和丙烯酸(AA)为功能单体等,在复合乳化剂OP-10/SDBS、OP-10/SE-10作用下分别制备了纸/塑、塑/塑复膜胶。结果表明:SE-10的乳化效果优于SDBS,前者可有效提高复膜胶的初粘力和剥离强度,并可有效降低乳胶粒的平均粒径;以OP-10/SE-10作为复合乳化剂,当w(AA)=8.3%时,复膜胶的初粘力和剥离强度均达到最大值,并且其热稳定性相对较好。With sodium dodecyl benzene sulfonate （SDBS） as anionic emulsifier, octyl phenol ethoxylates-10 （OP-10） as nonionic emulsifier,SE-10 as polymerizable emulsifier,styrene（St） as hard monomer,butyl acrylate（BA） as soft monomer and acrylic acid （AA） as functional monomer, the laminating adhesives for paper/plastic and plastic/plastic were prepared by OP-10/SDBS or OP-10/SE-10 composite emulsifier. The results showed that the emulsification effect of SE-10 was better than that of SDBS, the former could effectively improve the adhesive＇s initial tack and peeling strength, and could effectively reduce the average particle size of emulsion particles. The laminating adhesive with OP-10/SE-10 as composite emulsifier had maximal initial tack and peeling strength,and better thermal stability when mass fraction of AA was 8.3%.
