综述了植物纤维基聚氨酯的制备和性能,以及聚氨酯阻燃性能方面的研究进展。植物纤维基聚氨酯可以由植物纤维或其组分经过适当的降解制成的多元醇,再与异氰酸酯反应得到。其机械性能已基本达到石油基聚氨酯的指标。同时具有良好的生物降解特性。聚氨酯的阻燃技术主要包括添加型阻燃与结构型阻燃。添加型阻燃剂中,磷系阻燃剂是目前使用最广的阻燃剂。植物纤维基聚氨酯较少采用结构型阻燃技术。
綜述瞭植物纖維基聚氨酯的製備和性能,以及聚氨酯阻燃性能方麵的研究進展。植物纖維基聚氨酯可以由植物纖維或其組分經過適噹的降解製成的多元醇,再與異氰痠酯反應得到。其機械性能已基本達到石油基聚氨酯的指標。同時具有良好的生物降解特性。聚氨酯的阻燃技術主要包括添加型阻燃與結構型阻燃。添加型阻燃劑中,燐繫阻燃劑是目前使用最廣的阻燃劑。植物纖維基聚氨酯較少採用結構型阻燃技術。

The preparation techniques and properties of lignocellusic-based polyurethane as well as the progress on enhancement of their flame resistant properties were reviewed. The lignocellusie-based polyurethane materials can be synthesized from diisocyanate and bio-polyol. The bio-polyol could be obtained from the degradation products of plants. Biodegradability and thermal stability of lignoeellusic-based polyurethane have been improved more significant than conventional polyurethane products. The addition of fire retardant into polyurethane formulations or flame-retardant polyols were applied to improve flame retardancy. The phosphates were utilized commonly as flame-retardants.
