摘　　要：采用种子乳液聚合法制备了一种聚丙烯酸酯乳液胶粘剂,研究了软硬单体比例、功能单体比例、乳化剂用量、引发剂用量等对乳液胶粘剂剥离强度的影响。结果表明,最佳的聚合工艺是:软硬单体比例为1.5、功能单体占单体总量的4%、乳化剂用量为单体总量的3%、引发剂用量为单体总量的0.6%。将得到的乳液胶粘剂用于镀铝膜复合,剥离强度能够达到1.5 N/15 mm左右,可以满足实际使用要求。By seed emulsion polymerization, a kind of waterborne acrylic emulsion adhesive was prepared. Effects of soft/hard monomer ratio, functional monomer ratio, emulsifier amount and initiator amount on peeling strength of the adhesive were studied. The results showed that the best polymerization condition is as follows：the soft/hard mon- omer weight ratio is 1.5, the functional monomer amount is 4% by total monomer weight, the emulsifier amount is 3% by total monomer weight and the initiator amount is 0.6% by total monomer weight. The adhesive was applied in the lamination of vacuum metallized film by dry-type lamination. Final peeling strength can come to about 1.5 N/ 15mm. This is very satisfied with factual application need.
