摘　　要：聚氨酯乳液由于性能优异已广泛应用于建筑、皮革、金属防腐等领域的涂装与防护。现有聚氨酯乳液大多为石油基产品,出于可持续发展的需要,伴随生物基原料的快速发展和大规模商业化,生物基聚氨酯乳液获得快速发展。该文综述了合成聚氨酯乳液的生物基原料和助剂,包括生物基异氰酸酯、多元醇、扩链剂、丙烯酸(酯)单体以及其他生物基原材料,同时分析了木质素基、植物油基、非天然单体以及其他生物基聚氨酯乳液的新进展,指出了生物基聚氨酯乳液面临的主要问题,包括原材料供应不足、成本高和产物性能差等,展望了生物基聚氨酯乳液在无溶剂、高生物基含量和多功能等产品的发展前景。Polyurethane emulsions have been widely used in painting and protection in construction,leather,metal anti-corrosion and other fields due to their excellent performances.Most of the existing polyurethane emulsions are petroleum-based products.With the need for sustainable development as well as the rapid development and large-scale commercialization of bio-based raw materials,bio-based polyurethane emulsions have achieved rapid development.Herein,bio-based raw materials and additives for the synthesis of polyurethane emulsions,including bio-based isocyanates,polyols,chain extenders acrylic acid(acrylate)monomers and other modified raw materials were reviewed.Recent progress on lignin-based,vegetable oil-based,unnatural monomer bio-based and other bio-based polyurethane emulsions was analyzed.Main problems faced by bio-based polyurethane emulsions,including insufficient raw material supply,high cost and poor product performance were discussed.Development directions of bio-based polyurethane emulsions in solvent-free,high bio-based content and multi-functional products were prospected.
