【Abstract】 Using methanol as the initiator, an epoxy ethane/epoxy propane random copolyether was synthesized from epoxy ethane and epoxy propane. This copolyether was then subjected to an esterification reaction with phosphorus pentoxide to synthesize an epoxy ethane/epoxy propane random copolyether phosphate ester. The structure of the product was characterized using nuclear magnetic resonance, infrared spectroscopy, and gel permeation chromatography(GPC). The synthesized epoxy ethane/epoxy propane random copolyether phosphate ester was applied to solvent-based polyurethane(PU) and nitro(NC) wood paint systems, and its application performance was studied. The results indicated that the resulting coatings exhibited excellent color development, color difference upon fingerprinting, and storage stability.更多还原
