摘　　要：在酚醛泡沫发泡过程中,添加木质素,对酚醛泡沫进行改性,并对制备得到的改性的酚醛泡沫和未改性的酚醛泡沫进行比较与研究。红外光谱(IR)的结果表明,增韧改性后的酚醛泡沫的组分变化不大。扫描电子显微镜分析(SEM)结果表明,增韧改性后的酚醛泡沫的内部孔径的表面形貌更均一稳定,改善了泡孔结构,使泡孔尺寸显著减小,泡孔密度明显增大。拉伸压缩强度测试结果表明,增韧改性后的酚醛泡沫具有更好的拉伸强度和压缩强度。In the process of phenolic foam foaming, adding lignin can improve the property of phenolic foam. Compared with the properties between improved phenolic foam and pure phenolic foam, the results of Infrared Spectroscopy (IR) showed that the constituents of toughened phenolic foam has rarely changed. The results of Scanning Electron Microscope(SEM) showed that the morphology of the porous structure was more uniform, smaller cellular size and larger cell density. The results of the tensile and compression strengthes showed that the mechanical property were obviously enhanced.
