With vinyl acetate(VAC) as the hard monomer, butyl acrylate (BA) and 2-Ethylhexyl acrylate (2-EHA) as the soft monomer, acrylic acid(AA) as the crosslinking monomer, polyvinyl alcohol (PVA-1788) as the protective colloid, alcohol polyoxyethylene ether(AEO-9) and sodium dodecyl sulfate (SDS) as the emulsifier, potassium persulfate (K2S2O8) as the initiator, hardcore soft shell emulsion was synthesized. The core-shell particle structure was designed. The effect of soft and hard monomer, protective colloid, emulsifiers on tack, viscosity and size and distribution of particles of adhesives were studied. The results have shown that the hardcore softshell vinyl acetate-acrylate emulsion adhesives have good tack, low viscosity and narrow distribution of particle size. It can meet the requirements of high-speed cigarette filter tipping for punching water-paper.
