摘要

Agricultural waste reuse is the main strategy for developing sustainable energy sources.in the paper, Biomass conversion was carried out by reed liquefaction. Reed-based polyol (R-L) was prepared with liquefaction reagents (polyethylene glycol 400 and gallic acid) and catalysts (sulfuric acid). Then the ring-opening reaction between R-L and epichlorohydrin was accomplished by boron trifluoride as catalyst and the ring-closing reaction was further realized under alkaline, reed-based epoxy resin (R-EP) with epoxy value of 0.216 mol/100 g and relative molecular weight of 7368 was obtained. The epoxy coatings with different properties were prepared by varying curing agents; and the waterborne reed-based epoxy emulsion with excellent stability was synthesized by radical polymerization using α-methacrylic acid as a grafting monomer, butyl acrylate as a soft functional monomer, and styrene as a hard functional monomer, N,N-dimethylethanolamine as a neutralizing reagent. Reed-based coatings have good mechanical properties and are expected to replace petroleum-based epoxy resins.
