Synthesis and Properties of Fumaropimaric Acid-based Waterborne Polyurethane Modified by Epoxy Resin
摘要
Abstract
Fumaropimaric acid-based waterborne polyurethane ( FWPU) emulsion modified by epoxy resin ( EP) was synthesized. Influences of epoxy E-51 content on performances of emulsion and film were discussed. The results showed that when the content of E-51 was 3%, the tensile strength, water absorption, elongation at break and pendulum hardness of the film was 35. 6 MPa, of 10. 2%, of 410. 2% and 0. 89, respectively. The morphology and structure of the film and emulsion were characterized by transmission electron microscopy ( TEM ) , Fourier transform infrared spectroscopy ( FT-IR ) , differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA). It was verified by FT-IR analysis that the hydroxyl and epoxy groups in EP participated in reaction, and part of them formed network structure by crosslinking. The water resistance, thermal stability, mechanics performances and chemical resistance of films were improved with increase of EP content.关键词
