摘　　要：介绍了以丙烯酸、苯乙烯、丙烯酸丁酯、丙烯酸羟丙酯为单体,采用过硫酸铵作为引发剂,以非离子乳化剂聚氧乙烯醚(OP-10)和阴离子乳化剂十二烷基硫酸钠(SDS)作为复合乳化剂,经过乳液聚合,制得了一种水性涂料用缔合型增稠剂。考察了丙烯酸单体含量、乳化剂用量对乳液性能和增稠剂黏度的影响。优化了反应条件,反应过程和最终乳液都很稳定。In this paper,acrylic acid,styrene,butyl acrylate and hydroxypropyl acrylate as monomers,using ammonium persulfate as initiator,nonionic emulsifier OP-10 and anionic emulsifier Sodium dodecyl sulfate(SDS)as emulsifier,through emulsion polymerization,a kind of associative thickener for waterborne coatings was prepared.The effects of acrylic monomer content and emulsifier content on the properties of emulsion and viscosity of thickener were investigated.The reaction conditions were optimized,and the reaction process and the final emulsion were stable.
