The synthesis of polyacrylic emulsion reacting at low temperature

Taking potassium persulfate(KPS) as initiator,butyl acrylate(BA) and ethylhexyl acrylate(EHA) as soft monomers,vinyl acetate(PVA) as hard monomer,acrylic acid(AA) as functional monomer,TM-200 as ross-linking mononmer,polyacrylic printing adhesive at low temperature is synthesized.The best formulation of adhesive is as follows: emulsifier dosage 0.8%,cross-linking monomer 2.5%,reacting temperature 70～75℃,pre-emulsion dripping time 90min,holding time 60min,pre-emulsion dripping rate 0.5mL/s,stirring speed 250～400r/min.
