                     摘 要:为了解决水性生物基聚氨酯力学性能较低的问题,以生物基多元醇(蓖麻油与异山
                 醇)、异佛尔酮二异氰酸酯、2,2-羟甲基丙酸、季戊四醇三丙烯酸酯和三乙胺为原料,合成了水性光固
                 化生物基聚氨酯。通过 立叶变换红外光谱仪、核磁共振波谱仪、Zeta电位及纳米粒度分析仪等对乳
                 液结构进行表征,并对涂膜的力学性能、透过率、基本性能进行分析。结果表明:随着异山 醇含量
                 的增加,涂层的拉伸应力从从 4. 9 MPa 增长到 26. 8 MPa,断裂伸长率从 269% 下降至 4. 1%;在可见光
                 波段范围内各涂层光透过率均维持在 90% 以上。因此,在合适的蓖麻油与异山 醇的配比下生物基
                 聚氨酯涂膜的力学性能显著提升,并且在可见光波段具有良好的透明度。

                 polyurethane,a waterborne UV-curable bio-based polyurethane was synthesized using bio-based

                 acid,pentaerythritol  triacrylate  and  trimethylamine. The  structures  of  emulsion  were
                 characterized by Fourier transform infrared spectroscopy(FT-IR),nuclear magnetic resonance
                 spectroscopy,zeta  potential  instrument  and  nanoparticle  size  analyzer. The  mechanical
                 properties,ransmittance and other basic properties of coating were also studied. The results

                 26. 8 MPa,he elongation at break decreased from 269% to 4. 1%,and the light transmittance
                            t
                 of each coating remained above 90% in the visible light. Therefore,he mechanical properties
