摘要

AbstractA quaternary ammonium‐containing cationic resin is prepared by the ring‐opening reaction of epoxy resin and tertiary amine with the presence of a proton donor. Its emulsion can form a uniform polymer film on the cathodic metal by electrodeposition. In this study, the reaction conditions to prepare the quaternary ammonium resin from epoxy resin and tertiary amine, and effects of different proton donors on this reaction, were examined by gel permeation chromatography and infrared. Meanwhile, distinctions of electrodeposition properties between the quaternary ammonium resin and the tertiary amine acid salt resin were considered. Finally, the electrodeposition mechanism of quaternary ammonium resin was also determined. The results show that the quaternary ammonium resin prepared by triethylamine (TEA) and Epon 1004 has better solubility and emulsification than the tertiary amine acid salt resin prepared by diethylamine (DEA) and Epon 1004. Rupture voltage of this quaternary ammonium resin was very low because it was prepared by full‐alkyl group tertiary amine. Therefore, this kind of quaternary ammonium resin was not suitable for use for the electrodeposition resin individually. But when this quaternary ammonium resin was added to the tertiary amine acid salt resin, the deposited yield was much increased. © 1993 John WileySon
