摘　　要：以丙烯酸酯类为主要原料,以烯丙基烷基磺基琥珀酸双酯钠盐M10-S为反应型乳化剂,采用乳液聚合方法制备了一种可剥离型压敏胶乳液。探讨了N-羟甲基丙烯酰胺(NAM)、M10-S、增塑剂及基材对压敏胶性能的影响。结果表明,当NAM用量为总单体质量2.0%,M10-S为单体总质量0.6%,用总乳液质量20%的邻苯二甲酸二辛酯(DOP)为增塑剂,PP或不锈钢为基材时压敏胶具有较好的可剥离性及综合性能。The removable water-borne pressure-sensitive emulsion adhesive was prepared by seed emulsion polymerization with acrylates as the main monomers. The effects of N-methylol acrylamide（NAM）, polymeriable emulsifer （M10-S）, plasticizer and substrates on the properties of adhesive were investigated. The results indicated that the adhesive is removable and has optimal properties when the weight ratio of NAM and total monomers is 2 ： 100, the weight ratio of M10-S and total monomers is 0.6 ： 100, the weight ratio of plasticizer （ di-n-butyl phthalate ） and latex is 2.0% and the substrate is polypropylene（PP） or stainless steel.
