摘　　要：本文研究了聚乙烯亚胺类锚固剂(AC剂)对挤出复合工艺制备的多层复合膜粘结强度的影响。以双向拉伸聚丙烯(BOPP)、双向拉伸聚对苯二甲酸乙二醇酯(BOPET)、双向拉伸尼龙(BOPA)为基材,聚乙烯亚胺类AC剂可显著提高复合膜的剥离强度,提高幅度可达2倍以上。采用于两层乃至三层基材制备多层复合膜时,聚乙烯亚胺类AC剂复合膜的剥离强度仍可得到有效地提高。对于高阻隔结构PET/VMPET/IPE,随着聚乙烯亚胺类AC剂的涂布,其内层剥离强度可达3.2 N/15 mm,拓宽了挤出复合的应用范围。This study deals with the effect of polyethylenimine(PEI)anchoring coating(AC)agent on the adhesive strength of extrusion laminating films.The results show that the PEI AC agent can highly enhance the peeling strength of laminating films based on biaxially oriented polypropylene(BOPP),biaxially oriented polyethylene terephthalate(BOPET),biaxially oriented polyamide(BOPA)and so on.When the PEI AC agent is used in the lamination films with two or three layers base films,the peeling strength can also be enhanced.Furthermore,with the addition of PEI AC agent,the inner layer peeling strength of PET/VMPET/IPE can be 3.20 N/15 mm,which may promote the application of extrusion laminating.
