Abstract
Polyethylene glycol methacrylate (PEGMA) oligomer was synthesized in this study and then co-polymerized with other acrylate monomers to obtain poly-acrylate (PA) resin with PEO (polyethylene oxide) side chain. The synthesized poly-acrylate resin was coated on glass-fiber fabric for de-emulsification and coalescence of water-in-oil emulsion. The chemical structure and composition of PEGMA and PEGMA containing poly-acrylate resin was characterized by 13C NMR, HPLC and FTIR. The wetting behavior of poly-acrylate resin films were evaluated by water contact angle (WCA) method. Micro-morphology of glass-fiber fabric was observed by SEM. The pore size, air permeability, tensile strength, de-emulsification and coalescence performance of glass-fiber fabric was tested. The results show that PEGMA oligomer and PEGMA containing poly-acrylate resin were successfully synthesized. The cured co-polymer films present excellent diesel-resistance property. The pore size and air permeability of the co-polymer coated glass-fiber fabric are well maintained while the tensile strength is greatly improved. The wetting behavior of PEGMA containing poly-acrylate resin indicates that the PEO side chain of the co-polymer can migrate to the film surface when contacting with water droplet, therefore help breaking the absorption equilibrium of surfactants on the water/oil interface, and lead to excellent de-emulsification and coalescence performance of the coated glass-fiber fabric.
