以甲基丙烯酸甲酯(MMA)为硬单体、丙烯酸丁酯(BA)为软单体、丙烯酸(AA)为功能单体、N-羟甲基丙烯酰胺(NMA)为交联单体、过硫酸铵(APS)为引发剂、十二烷基硫酸钠(SDS)和壬基酚聚氧乙烯醚(NP-40)为复合乳化剂,采用预乳化半连续乳液聚合法合成了自交联型丙烯酸酯涂料印花黏合剂。研究结果表明:当m(MMA)∶m(BA)=0.38∶1、w(NMA)=3%、w(AA)=2.5%～3.0%、w(复合乳化剂)=3.0%且m(SDS)∶m(NP-40)=1∶(1.5~2.0)、w(APS)=0.8%、75~80℃聚合3 h和85℃保温1 h时,相应乳液的综合性能相对最好。
Using methyl methacrylate (MMA) as a hard monomer, butyl acrylate (BA) as a soft monomer, acrylic acid (AA) as a functional monomer and N-methylol acrylamide (NMA) as a crosslinking monomer, Ammonium persulfate (APS) as initiator, sodium dodecyl sulfate (SDS) and nonylphenol polyoxyethylene ether (NP-40) as the composite emulsifier were synthesized by semi- Acrylic paint printing adhesive. The results show that when m (MMA): m (BA) = 0.38:1, w (NMA) = 3%, w AA = 2.5% ~ 3.0%, w (composite emulsifier) = 3.0% SDS: m (NP-40) = 1: 1.5-2.0, w (APS) = 0.8%, polymerization at 75-80 ℃ for 3 h and incubation at 85 ℃ for 1 h.
