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。
Sodium dodecyl benzene sulfonate (SDBS) as anionic emulsifier, octylphenol polyoxyethylene ether-10 (OP-10) as nonionic emulsifier, allyloxy nonylphenoxypropane Polyoxyethylene ether sulfate ammonium sulfate (SE-10) is a polymerizable emulsifier, styrene (St) is a hard monomer, butyl acrylate (BA) is a soft monomer and acrylic acid Paper / plastic, plastic / plastic laminating adhesive were prepared under the action of compound emulsifier OP-10 / SDBS and OP-10 / SE-10 respectively. The results showed that the emulsifying effect of SE-10 was better than that of SDBS. The former could effectively increase the initial tack and peel strength of the adhesive and reduce the average size of the adhesive. With OP-10 / SE-10 as emulsifier Agent, w (AA) = 8.3%, the initial adhesive strength and peel strength of the laminating adhesive reached the maximum, and its thermal stability is relatively good.
