摘  要:以竹焦油为原料全部替代苯酚,与糠醛在碱性催化剂作用下,制备了竹焦油-糠醛热固性树脂(BTFF)。随反应时间和反应温度的增加,所制备的BTFF固体含量和黏度增大,游离糠醛含量减小,pH值9~10,密度1.20~1.30 g/mL。根据傅里叶变换红外光谱(FT-IR)分析,BTFF与苯酚-糠醛热固性树脂(PFF)结构相似;经差示扫描量热法分析,BTFF与PFF固化特性相近,固化温度(150℃)较低。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.
