Application of styrene-acrylate emulsion modified by crosslinker in water-based ink

With diallyl phthalate(DAP),heterocyclic methacrylate monomer(TRM WAM III),and acetoacetate-based ethyl methacrylate(AAEMA) as cross linker of traditional styrene-acrylate emulsion respectively,a styrene-acrylate emulsion modified by crosslinker was prepared by pre-emulsified semi-continuous emulsion polymerization.Then a water-based ink was prepared with styrene-acrylate emulsion modified by crosslinker as ink vehicle.The influences of some emulsions such as traditional styrene-acrylate emulsion,styrene-acrylate emulsion modified by crosslinker and similar import product were investigated on some properties such as rubbing fastness,stability and water resistance of water-based ink.The results showed that the styrene-acrylate emulsion modified by crosslinker had better calcium ion stability and freeze-thaw stability.The water-based ink,which was made from styrene-acrylate emulsion modified by TRM WAM III,had relatively better rubbing fastness(dry or wet rubbing grades at 9.0 or 6.0),stability,water resistance(water resistance time at 25 s),luster and tinting strength(100%).The styrene-acrylate emulsion modified by TRM WAM III used for water-based ink was feasible because its combination property was close to similar import product(JONCRYL 74-A).
