本文以不同含量的木质素磺酸钠为功能填料，制备了一系列蓖麻油基水性聚氨酯复合材料。研究并讨论了木质素磺酸钠含量对聚氨酯复合分散体粒径和贮存稳定性的影响。此外，对所得聚氨酯薄膜的热机械性能、热稳定性、力学性能和紫外吸收性能进行了表征。该复合分散体具有优异的储存稳定性，所得复合膜的生物含量高达70%。此外，木质素磺酸钠刚性苯环结构的增强作用以及聚氨酯基体与填料之间良好的相容性，使复合材料的拉伸强度和储能模量随木质素磺酸钠含量的增加而增加。由于木质素大分子的共轭结构，木质素磺酸钠的引入使复合材料具有良好的紫外吸收性能。本研究为制备环保型生物基水性聚氨酯复合材料提供了一种新的简便方法，可广泛应用于紫外线吸收涂料和防晒霜领域。
In this work, a series of castor oil-based waterborne polyurethane composites were prepared with different amounts of sodium lignosulfonate as functional filler. The effect of the sodium lignosulfonate contents on the particle size and storage stability of the polyurethane composite dispersions was studied and discussed. In addition, the thermo-mechanical, thermal stability, mechanical properties and UV absorption of the resulting polyurethane films were characterized. The composite dispersion exhibits excellent storage stability and the bio-content of the resulting composite films is high up to 70%. In addition, it was found that the tensile strength and storage modulus increased with increasing the sodium lignosulfonate contents due to enhancement effect from the rigid benzene ring structure of sodium lignosulfonate and good compatibility between polyurethane matrix and the filler. The introduction of sodium lignosulfonate into WPU matrix rendered the excellent UV absorption of the composites due to the conjugated structures of lignin macromolecular. This work provides a new simple method to prepare environmental friendly bio-based waterborne polyurethane composites, which could find widely application in the field of UV absorption coatings and sunscreen cream.
