摘要

A series of acrylate latexes for pigment printing binder were prepared by semicontinuous pre-emulsifying emulsion polymerization, using lipophilic glycidyl meth-acrylate (GMA), ethylene glycol dimethyl acrylate (EGDMA) and hydrophilic HA (containing hydroxyl, acylamino), N-methylol acrylamide (NMA) as cross-linking monomer. The influences of cross-linker type on the particle size, viscosity and film-forming rate of latex, cross-linking degree and tensile properties of latex film were studied. It was found that the latex particle size, viscosity and film-forming rate were closely related with the hydrophile-lipophile property of cross linkers. The acrylate latex synthesized with hydrophilic cross-linkers always exhibits the characteristics of larger particle size, lower film-forming rate, higher viscosity and pseudoplastic fluid. The cross-linking degree and tensile properties of latex film generally depend on the crosslinking groups of cross-linkers and their reactivity.
