| Résumé : |
Styrene-acrylic resin encapsulated C.I. Pigment Yellow 17 (PY17) and charge control agent (CCA) multicomponent composite particles were prepared by mini-emulsion polymerization. The characterization results of transmission electron microscopy, Fourier transform infrared spectroscopy, thermogravimetric analysis, and centrifugal sedimentation experiments all verified the encapsulation of PY17 and CCA. The effect of PY17 and CCA dosages on the morphology of multicomponent particles and influence of compound emulsifier dosage on the emulsion stability and the dispersity of latex particles were studied. When the mass fractions of monomers, PY17, CCA, and compound emulsifiers relative to deionized water were 5, 0.4, 0.1, and 0.375%, respectively, the emulsion showed excellent stability; meanwhile, the latex particles had a clear core–shell structure and the best dispersity. The average size of the multicomponent particles changed slightly with the different dosages of PY17, CCA, and compound emulsifiers. Colorimetric analysis of the samples indicated that encapsulation of PY17 may lead to a decrease in yellow value b* but had little effect on its tinctorial strength. |
