High-quality rigid polyurethane (PU) foam thermal insulation material has been developed solely using bio-polyols synthesized from second-generation bio-based feedstock. High functionality bio-polyols were synthesized from cellulose production side stream-tall oil fatty acids by oxirane ring-opening as well as esterification reactions with different polyfunctional alcohols, such as diethylene glycol, trimethylolpropane, triethanolamine, and diethanolamine. Four different high functionality bio-polyols were combined with bio-polyol obtained from tall oil esterification with triethanolamine to develop rigid PU foam formulations applicable as thermal insulation material. The developed formulations were optimized using response surface modeling to find optimal bio-polyol and physical blowing agent: c-pentane content. The optimized bio-based rigid PU foam formulations delivered comparable thermal insulation properties to the petro-chemical alternative.

仅使用由第二代生物基原料合成的生物多元醇，就开发出了高质量的硬质聚氨酯（PU）泡沫保温材料。通过环氧乙烷开环反应以及与不同多官能醇（如二甘醇、三羟甲基丙烷、三乙醇胺和二乙醇胺）的酯化反应，从纤维素生产侧流粗妥尔油脂肪酸中合成了高官能度生物多元醇。将四种不同的高官能度生物多元醇与通过粗妥尔油与三乙醇胺酯化反应得到的生物多元醇相结合，开发出了适用于保温材料的硬质PU泡沫配方。使用响应面模型对所开发的配方进行优化，以找到最佳生物多元醇和物理发泡剂：正戊烷含量。优化后的生物基硬质PU泡沫配方具有与石化替代品相当的保温性能。
