摘要

Syntheses and technology for preparation of cyan toner for dual component development by means of a suspension polymerization method is described. In this study, the organic phase, containing styrene monomer, n-butylacrylate, divinylbenzene, azo-bis-diisobutyronitrile, paraffin and Phthalocyanine Blue, was first dispersed into the aqueous phase, containing polyvinyl alcohol and sodium dodecylsulfate as suspension dispersants. Then dispersion was performed by a rotor-stator homogenizer, and subsequently the dispersion system was transferred to a three-orifice flask with a paddle stirring blade, where the polymerization reaction occurred. Correlations between amount of crosslinking agent and molecular weight of insoluble proportion in toners, and between gel content and some rheological behavior, such as viscous flow temperature, and melt index are discussed. Effects of Phthalocyanine Blue on charge-to-mass ratio and the interaction between resin in toners and Phthalocyanine Blue were studied. It was suggested that gel formation rather than increasing the molecular weight of the insoluble portion of the toner resulted in a change in rheological behavior according to the measured data of gel content, GPC, DSC, softening point and melt index. The Phthalocyanine Blue cause a notable increase in charge-to-mass ratio. The related infrared spectra suggested that the interactions between Phthalocyanine Blue T and resin mainly involved physical forces.
