Abstract

In this study, bio-oil from the fast pyrolysis of renewable biomass was used as the raw material to synthesize bio-oil phenol formaldehyde (BPF) resin-a desirable resin for fabricating phenolic-based material. During the synthesis process, paraformaldehyde was used to achieve the requirement of high solid content and low viscosity. The properties of BPF resins were tested. Results indicated that BPF resin with the bio-oil addition of 20% had good performance on oxygen index and bending strength, indicating that adding bio-oil could modify the fire resistance and brittleness of PF resin. The thermal curing behavior and heat resistance of BPF resins were investigated by differential scanning calorimetry (DSC) and thermal gravimetric analysis (TGA). Results showed that adding bio-oil had an impact on curing characteristics and thermal degradation process of PF resin, but the influence was insignificant when the addition was relatively low. The chemical structure and surface characteristics of BPF resins were determined by Fourier transform infrared (FTIR) spectroscopy and scanning electron microscopy (SEM). The analysis demonstrated that adding bio-oil in the amount of 20% was able to improve the crosslinking degree and form more hydrocarbon chains in PF resin.

摘要

在本研究中，可再生生物质快速热解产生的生物油被用作原料来合成生物油酚醛（BPF）树脂——一种用于制造酚醛基材料的理想树脂。在合成过程中，使用多聚甲醛来满足高固含量和低粘度的要求。对BPF树脂的性能进行了测试。结果表明，生物油添加量为20%的BPF树脂在氧指数和弯曲强度方面具有良好性能，这表明添加生物油可以改善酚醛树脂的耐火性和脆性。通过差示扫描量热法（DSC）和热重分析（TGA）研究了BPF树脂的热固化行为和耐热性。结果表明，添加生物油对酚醛树脂的固化特性和热降解过程有影响，但当添加量相对较低时，这种影响不显著。通过傅里叶变换红外（FTIR）光谱和扫描电子显微镜（SEM）确定了BPF树脂的化学结构和表面特征。分析表明，添加20%的生物油能够提高酚醛树脂的交联度并形成更多的烃链。
