| Résumé : |
Monomethacryloyloxy-terminated fluorinated oligomers (PPFOMA-GMA and PHFBMA-GMA) and methyl allyl alcohol polyoxyethylene ether-modified epoxy resin (HPEGEA) were successfully synthesized and used as reactive additives and emulsifier for epoxy acrylate, respectively. FTIR, 1H NMR, and GPC were used to characterize the structures of PPFOMA-GMA, PHFBMA-GMA, and HPEGEA. The influence of the concentrations of PPFOMA-GMA and PHFBMA-GMA on the properties of waterborne epoxy acrylate (WEA) resin coatings was investigated. The surface energy of waterborne epoxy acrylate coating was decreased from 38.20 mN/m to 15.31 mN/m by adding just 0.21 wt% PPFOMA-GMA, indicating its high effectiveness in improving the hydrophobic properties of the surface. The surface compositions of the WEA resin coatings (with 0.85 wt% PPFOMA-GMA or 0.85 wt% PHFBMA-GMA) were characterized by XPS. The XPS results confirmed the quantitative enrichment of fluorine atoms on the surface. What is more, the physical properties of waterborne epoxy acrylate coatings prepared with different concentrations of fluorinated reactive additive, such as optical transmittance, adhesion (on glass, PET, and tinplate), pencil hardness, water absorption, and thermal properties, were also analyzed in detail. Hence, the waterborne epoxy acrylate coatings prepared with low concentrations of reactive additives were economical and have potential for large-scale industrial applications. |
