Aqueous emulsion acrylic adhesive was prepared by batch emulsion polymerization With 2-ethylhexyl acrylate (2-EHA) and butyl acrylate (BA) as soft monomers, methyl methacrylate (MMA) as hard monomer, acrylic acid (AA), acrylic amide (AM) and hydroxyethyl acrylate (HEA) as hydrophilic functional monomers, dodecanethiol (NDM) as molecular weight regulator, Sodium dodecyl benzene sulfonate (SDBS) and octyl phenol polyoxyethylene ether (op-10) as mixed emulsifiers, ammonium persulfate (APS) as initiator, and distilled water (H2O) as solvent. The effects of monomer, emulsifier, initiator, reaction temperature and time on the properties of the synthetic adhesive were also discussed. The emulsifier accounted for 4% of the monomer, and the initiator accounted for 1%. This method greatly reduces the preparation time, improves the preparation efficiency, and facilitates the operation and production. The prepared aqueous acrylate emulsion was white and blue light, stable and small odor, good water resistance, solid content of 42.13%, viscosity of 857.1 mPa·s, peel strength of 2.647 N·(25mm)–1 through calcium stability. waterborne acrylate adhesive by water as a dispersion medium and have the advantages of high solid content, safety, non-toxicity and low cost, which can meet the needs of packaging and printing fields.
