| 摘 要： | 研究了低密度聚乙烯与马来酸酐的接枝共聚物LDPE-g-MAH对木质素/低密度聚乙烯共混体系热性能、红外光谱分析力学性能、流变行为以及微观形态的影响.DSC-TG综合热分析表明添加增容剂的共混物的熔融温度降低，热稳定性提高;红外光谱分析表明木质素与LDPE-g-MAH之间存在分子间氢键相互作用，流变性能分析表明共混物体系具有可加工性;扫描电子显微镜（SEM）照片显示添加增容剂后分散相尺寸明显减小，分散程度提高;PE-g-MAH有效提高了木质素/聚乙烯吹塑薄膜的力学性能，且当木质素、聚乙烯和LDPE-g-MAH质量比为25/75/10时，力学性能最优.

| Abstract: | The blends low-density polyethylene(LDPE) and lignin were compatilized by the graft copolymer of maleic anhydride(MAH) onto low-density polyethylene.The effects of LDPE-g-MAH contents on thermal properties,FTIR spectral analyses mechanical properties, rheological behavior and morphology of LDPE/lignin blends were investigated.The results of TG-DSC indicated the addition of compatibilizer decreased melting temperature, improved thermal stability.FTIR elucidated the existence of an intermolecular hydrogen-bonding interaction between lignin and LDPE-g-MAH.Rheological behavior analysis for the blends demonstrated that the blends were processable.Scanning electron microscopy (SEM) micrograph showed that the compatibilizer LDPE-g-MAH could improve the dispersity of lignin in LDPE and reduce the dispersed phase size.The introduction of LDPE-g-MAH effectively improved the mechanical properties of LDPE/lignin blow film.When mass ratios of lignin, LDPE and LDPE-g-MAH were 25/75/10, the blow film had excellent mechanical property. |
