摘　　要：以甲酚液化生物质得到的生物油,多聚甲醛及不同二胺制备了生物油苯并恶嗪酚醛树脂(bio BOZ)。利用红外光谱,凝胶色谱,气相色谱-质谱联用仪,示差扫描量热仪、热重分析及凝胶时间测定对树脂的性能进行了表征。结果表明:中温甲酚液化生物油更适合酚醛树脂的制备。以生物油,聚醚胺和甲醛制备的生物苯并恶嗪酚醛树脂具有良好的流变性。分子质量较大的聚醚胺作为胺类单体时树脂固化温度稍低,酸催化下可明显降低树脂固化温度。随着胺类单体中乙二胺用量的增加,生物苯并恶嗪酚醛树脂的残炭率随之增加。热分解温度随着聚醚胺分子质量增大而稍有增大,且随着乙二胺用量增加而有所降低。The bio-oil modified benzoxazine resins（bio BOZ） were prepared with bio-oil from cresol liquefied biomass, paraformaldehyde and different diamines. The properties of bio BOZ were characterized using infrared spectroscopy, gel chromatography, gas chromatography-mass spectrometry, differential scanning calorimetry, thermal gravimetric analysis and determination of the resin gel time.The results showed that the bio-oil by cresol liquefied at moderate temperature was more suitable for the preparation of the phenolic resin. The bio BOZ prepared with bio-oil, polyether amines and formaldehyde had good rheology. The larger molecular weight of polyether amines as the amine monomer, the lower curing temperature of the resin. The resin curing temperature could be significantly reduced by acid catalyst. With the increasing of ethylene diamine amount in monomer, the char yield of bio BOZ was increased. The thermal decomposition temperature of bio BOZ was slightly increased with the increasing of polyether amine molecular weight and decreased with the increasing of ethylene diamine amount.
