The Research And Applications Of Acrylate Copolymer Emulsion Adhesives

Acrylate copolymer emulsion adhesive is one of the important applications for emulsion polymerization. It is also one of the polymer emulsion adhesive which is developed most fast since 1980s.Based on the research status of acrylate copolymer emulsion adhesive,the emulsion copolymerization is performed according to molecule design theory.We optimize the synthesis technics and adjust the combination of monomer and get the acrylate copolymer emulsion.We use it for paper-plastic adhesive and ornaments of autocar adhesive;and expect to solve the problem about acrylate copolymer emulsion adhesive and develop the properties of copolymer emulsion adhesive.The measurements,such as TEM;FTIR;DSC and so on ,are employed to characterize the struture of the product. We analyze and discuss someinfluencingfactors,suchassynthesis,protectingcolloid,reactiontimes,initiator,e mulsifier,copolymer monomer,tackifier resin and pH,on the properties of acrylate copolymer emulsion adhesive.The main results include that: (l)The low solid content acrylate copolymer emulsion is prepared. And some disadvantages of traditional paper-plastic adhesive have been solved,for example ,the poor water resistance and first-viscousness at low temperature.(2) We use the technics of seed emulsion polymerization combining half-continuous dropping and get the environmental water-based acrylate copolymer emulsion adhesive for ornaments of autocars.It's high solid content and can self-crosslink at room temperature.There are advantages in short dryness time, high first-viscousness,and without polluting.
