ABSTRACT The aim of this work is to investigate the chemical, physical, thermal and mechanical properties of bio-oil-phenol–formaldehyde (BPF) resin synthesized with catalytic pyrolysis oil. In this way, catalysed and uncatalysed pyrolysis processes were carried out in a vacuum pyrolysis reactor at the temperature of 500°C. Sodium hydroxide (NaOH) and potassium hydroxide (KOH) were used as catalysts in the catalysed pyrolysis processes. The BPF resins were synthesized using the bio-oil at 10 wt%, 20 wt%, 30 wt%, 40 wt% and 50 wt% phenol replacement levels. The chemical composition of the bio-oil was analyzed by GC/MS analysis. The thermal characteristics and chemical structures of the resins were characterized by TGA and FT-IR analysis, respectively. Physical properties including pH, viscosity, solid content and gel time of the resins were determined. Oriented Strand Board (OSB) were manufactured to evaluate the mechanical performances of modified resins. The BPF resins were successfully synthesized with phenol, bio-oil and formaldehyde. BPF resins synthesized with catalytic bio-oils showed better thermal stability than BPF resin synthesized with non-catalytic bio-oil. The mechanical test results showed that the IB strengths of OSBs made with BPF resins synthesized by use of NaOH exhibited better performance than OSBs commercial PF made.

催化裂解油合成生物基酚醛树脂及其对定向刨花板性能的影响

摘要 这项工作的目的是研究用催化裂解油合成的生物油-苯酚-甲醛 (BPF) 树脂的化学、物理、热和机械性能。这样，催化和非催化热解过程在真空热解反应器中在 500°C 的温度下进行。氢氧化钠 (NaOH) 和氢氧化钾 (KOH) 用作催化热解过程中的催化剂。BPF 树脂是使用生物油以 10 wt%、20 wt%、30 wt%、40 wt% 和 50 wt% 苯酚替代水平合成的。通过GC/MS分析来分析生物油的化学成分。树脂的热特性和化学结构分别通过 TGA 和 FT-IR 分析表征。物理特性，包括 pH 值、粘度、测定树脂的固含量和凝胶时间。制造定向刨花板 (OSB) 以评估改性树脂的机械性能。BPF树脂与苯酚、生物油和甲醛成功合成。用催化生物油合成的 BPF 树脂比用非催化生物油合成的 BPF 树脂表现出更好的热稳定性。力学测试结果表明，用NaOH合成的BPF树脂制备的OSBs的IB强度比商业PF制备的OSBs表现出更好的性能。用催化生物油合成的 BPF 树脂比用非催化生物油合成的 BPF 树脂表现出更好的热稳定性。力学测试结果表明，用NaOH合成的BPF树脂制备的OSBs的IB强度比商业PF制备的OSBs表现出更好的性能。用催化生物油合成的 BPF 树脂比用非催化生物油合成的 BPF 树脂表现出更好的热稳定性。力学测试结果表明，用NaOH合成的BPF树脂制备的OSBs的IB强度比商业PF制备的OSBs表现出更好的性能。
