Preparation and Characterization of the Bamboo Tar-furfural Thermosetting Resin

Bamboo-tar furfural thermosetting resin(BTFF) was synthesized by bamboo tar and furfural under catalysis of alkaline.The solid content and the viscosity of the BTFF increased,with the increase of reaction temperature and time,while the residue furfural contents reduced.The pH of the prepared BTFF was 9-10,and the density was 1.20-1.30 g/mL.The properties of BTFF were analyzed by Fourier transform infrared spectroscopy(FT-IR) and differential scanning calorimetry(DSC).The results showed that the chemical structures of BTFF were similar to those of the phenol-furfural resin(PFF).By DSC,the BTFF was cured at a low temperature(150 ℃) which was close to that of PFF.
