PREPARATION AND CHARACTERIZAION OF MODIFIED EPOXY RESIN FROM LIQUEFIED BAGASSE
Bagasse was rapidly liquefied in ethylene carbonate in the presence of sulfuric acid as the catalyst. Then the liquefaction product was used to prepare epoxy resin in two ways. One is to mix the liquefied bagasse with diglycidyl ether of bisphenol A and the other is to react the mixture of liquefied bagasse and bisphenol A with epichlorohydrin. The resin was cured with triethylene tetramine at 100℃ within 2 h. The mechanical properties of the epoxy resin prepared were evaluated. The thermal properties were also studied by differential scanning calorimetry and thermogravimetry. The adhesive shear strength of the cured resins containing liquefied bagasse achieved 22.5 MPa, which was drastically improved when compared to normal epoxy resin. The thermal stability of the epoxy resin was also improved by the introduction of liquefied bagasse.
