摘　　要：以丙烯酸丁酯、醋酸乙烯酯、丙烯酸、十二烷基硫酸钠、过硫酸铵、水性松香树脂等为原料,采用预乳聚合法成功制备了性能优良的水基乳液型纸塑复合粘合剂。讨论了软硬单体配比、引发剂、功能单体、增粘剂用量及聚合反应时间等因素对粘合剂的剥离强度和粘度的影响,确定了水基乳液型纸塑复合粘合剂的最佳工艺条件,各组分质量分数为:丙烯酸丁酯65.3%、醋酸乙烯酯21.2%、丙烯酸5.5%、十二烷基硫酸钠3.8%、过硫酸铵0.4%、水性松香树脂3.0%,聚合反应时间为2.5h。Butyl BA, vinyl acetate, acrylic acid, sodium sulfate, waterborne rosin resin were respectively used as soft monomer, hard monomer, functional monomer, emulsifier, initiator, adhesion agent to prepare water-based emulsion for paperplastic laminating adhesive through pre-emulsifying method. The effects of their concentrations on peeling strength and viscosity were studied in details. The optimum technique parameters were obtained as follows： butyl BA 65.3%, vinyl acetate 21.2%, acrylic acid5.5%, sodium sulfate 3.8%, ammonium per sulfate 0.4%, waterborne rosin resin 3.0%, polymerization reaction time 2.5h.
