摘　　要：用乙烯-醋酸乙烯共聚物(EVA)乳液、萜烯树脂乳液和阳离子型苯乙烯-丙烯酰胺共聚物研制了系列水基复膜胶,并考察了萜烯树脂乳液中乳化剂结构对复膜胶性能的影响。研究结果表明,作为交联剂的阳离子型苯乙烯-丙烯酰胺共聚物可大幅提高EVA乳液的黏度和剥离强度,其最佳加入量为0.5%(以EVA乳液的固形物为基准)。萜烯树脂乳液与EVA乳液的质量比值为0.3时,复膜胶的剥离强度最大。由高分子表面活性剂(HS-2)制得的萜烯树脂乳液增加复膜胶剥离强度的效果最好。A series of water-soluble paper/plastics laminating adhesives were prepared using an EVA emulsion, terpene resin emulsions and cationic styrene-acrylamide copolymer, and effects of surfactants in the terpene resin emulsions on properties of the adhesives were investigated. The results showed that the cationic copolymer was able to increase greatly viscosity and tensile strength of the EVA emulsion, The optimum dosage for the copolymer was 0.5 % based on mass of the EVA emulsion, The largest tensile strength was obtained at mass ratio 0.3 of the terpene resin emulsion and the EVA emulsion. Terpene resin emulsion prepared with polymeric surfactant （HS-2） performed the best effects in increasing tensile strength of the adhesives.
