摘　　要：以甲醇为引发剂,以环氧乙烷和环氧丙烷为原料合成环氧乙烷/环氧丙烷无规共聚醚,然后与五氧化二磷进行酯化反应,合成一种环氧乙烷/环氧丙烷无规共聚醚磷酸酯,并采用核磁共振、红外光谱和凝胶渗透色谱(GPC)对其结构进行了表征.将合成的环氧乙烷/环氧丙烷无规共聚醚磷酸酯应用于溶剂型聚氨酯(PU)、硝基(NC)木器漆体系中,并对其应用性能进行研究.结果表明,所制备漆膜具有优异的展色性、指研色差和储存稳定性.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.
