环氧改性水性醇酸树脂的研究进展

Progress in Epoxy Modified Waterborne Alkyd Resin

综述了目前国内产量较大,应用较广的环氧改性醇酸树脂常见的3种方法:物理共混改性、溶剂型环氧改性醇酸、环氧改性水性醇酸。同时介绍了影响环氧改性水性醇酸树脂制备及涂膜性能的多种因素,如环氧树脂的种类、一元脂肪酸种类与含量、油度等。最后对环氧改性水性醇酸树脂的应用前景进行了展望。

Alkyd resin is a resin that has been largely produced and intensively applied in domestic mar-ket. Three typical methods of alkyd resin modified with epoxy were reviewed： physical blending modifica-tion, solvent epoxy modified alkyd resin and waterborne epoxy modified alkyd resin. Meanwhile, factors af-fecting the preparation of waterborne alkyd resin modified with epoxy and the film performance were dis-cussed, such as types of epoxy resin, types, amount and oil length of mono fatty acid. Finally the applica-tion prospect of epoxy modified waterborne alkyd resin was described.
