Development of rosin modified acrylate emulsion PSA for label

In this paper, synthesis of acrylate core-shell copolymerization emulsion which was modified by disproportionated rosin was studied. Effects of emulsifier and addition process were investigated. The influences of initiator and disproportionated rosin were also studied. The technology and the proportion were optimized,in which the excellent acrylate emulsion PSA for label was obtained. They were as follows: complex emulsifier (SDS/OP-10) 3%~4%,the weight ratio of SDS/OP-10 1:3; (NH4)2S2O8 0.4%;disproportionated rosin 6%.
