摘要
以BA（丙烯酸丁酯）、MMA（甲基丙烯酸甲酯）、AA（丙烯酸）和HPA（丙烯酸羟丙酯）等作为主要单体，GMA（甲基丙烯酸缩水甘油酯）作为交联剂，采用半连续乳液聚合法制备了自交联型水基丙烯酸酯胶粘剂乳液，并将其应用于pvc（聚氯乙烯）／织物的粘接。研究结果表明：当m（软单体）：m（硬单体）=5：5、州（复合乳化剂）=3％～4％、埘（引发剂）=1．0％和W（GMA）=4％（均相对于总单体质量而言）时，胶粘剂乳液的综合性能相对最好，其平均粒径为126．8nm、乳液稳定性良好、胶膜吸水率（4．23％）相对较低、耐热性相对较好目PVC／织物的剥离强度（28．3N／25mm）相对最大。
With BA （butyl acrylate）, MMA （methyl methacrylate）, AA （acrylic acid ） and HPA （hydroxypropyl acrylate） as main monomers, GMA （glycidyl methacrylate） as cross linker, a water-based acrylate adhesive emulsion with self-crosslinking, which emulsion was used for bonding between PVC （polyvinyl chloride ） and fabric ,was prepared by semi-continuous emulsion polymerization. The research results showed that the adhesive emulsion had the relatively best combination property because its average particle size was 126.8 nm,emulsion stability was good,water absorpsion（4.23%） of adhesive film was relatively lower,heat resistance was relatively better, and peel strength（28.3 N/25 ram） between PVC and fabric was relatively maximal when mass ratio of re（soft monomer）：m（hard monomer） was 5：5,mass fractions of compound emulsifier,initiator and GMA were 3%-4%, 1.0% and 4% respectively in total monomers.
