Abstract
The low temperature environment friendly poly-acrylate emulsion adhesive is prepared by seed emulsion polymerization method. It means that, with butyl acrylic (BA), ethylhexyl acrylate (EHA), styrene (St) as soft or hard monomer, acrylic acid (AA) as functional monomer, potassium persulfate as initiator, HA as crosslinking monomer, poly-acrylate adhesive provided with excellent performance for pigment printing is synthesized. The effects of the hard monomer to soft monomer ratio, dosage of functional monomer, dosage of crosslinking monomer and chain transfer agent on the emulsion performance and pigment printing property are discussed. Finally, the optimum process condition of emulsion polymerization is confirmed as follows:the ratio of hard monomers to soft monomers is 1.218 8/1, the dosage of functional monomer is 1.8%, the dosage of crosslinking monomer is 2.6%, and chain transfer agent is 0.52%, dosage of adhesive is 30%, the curing time is 4 min.关键词
