摘要
聚氨酯是一种产品形态较多、性能较好的高分子材料,适用于各个行业的应用。由于石油资源逐渐枯竭,出现了环境问题,利用可再生资源合成高分子聚合物成为人们关注的热点。由于木质素可再生、可生物降解、非食用价值较高、功能性较强,可作为羟基提供源,替代石油基多元醇合成聚氨酯,而得到了广泛关注。近年来,木质素作为多元醇替代品被广泛地应用于聚氨酯领域(泡沫、涂料、胶粘剂),证明了木质素或改性木质素能赋予聚氨酯材料额外的功能,例如,提升了材料力学性能,赋予了材料疏水性、耐候性和热稳定性等。通过概述木质素结构、性质的多样性及木质素的功能化改性方法,分析木质素添加至聚氨酯产品中的潜在方法及其发展潜力和挑战,得到木质素应用于聚氨酯领域的潜在解决方案。最后,阐述了将木质素添加至聚氨酯产品(聚氨酯泡沫、涂料、胶粘剂)后,具有较大的发展潜力,提升了聚氨酯的性能。
Polyurethane is a polymer material with various product forms and excellent performance,which is suitable for applications in various industries.Due to the depletion of petroleum resources and related environmental problems,the use of renewable resources to synthesize polymers becomes a hot spot of concern.Lignin attracts widespread attention because of its renewable,biodegradable,high non-edible value,and strong functionality,and it is a source of hydroxyl to replace petroleum-based polyols to synthesize polyurethane.In recent years,lignin has been widely uesd in the field of polyurethane(foam,coatings,adhesives)as a substitute for polyols.Lignin or modified lignin proves to give polyurethane materials additional functions,such as improving the mechanical properties of materials,giving materials hydrophobicity,weather resistance and thermal stability,etc.By outlining the diversity of lignin structure,properties and the functional modification methods of lignin,dissing the potential ways of integrating lignin into polyurethane products,as well as the existing opportunities and challenges,and indicating the potential solutions for lignin in the field of polyurethane.Finally,illustratingthe great potential and performance-enhancing advantages of lignin incorporation into polyurethane products(polyurethane foams,coatings,adhesives).
