| 摘 要： | 采用熔融共混法制备了微晶纤维素（MCC）含量分别为50 ％、60 ％和70 ％的高密度聚乙烯（PE-HD）/MCC复合材料，研究了MCC含量对其力学性能、流变行为、热变形温度和断口形貌的影响。结果表明，加入MCC能有效提高PE-HD的弯曲强度、弯曲模量和拉伸强度，其中MCC含量为60 ％时材料力学性能最好；MCC的加入显著提高了PE-HD的热变形温度，且MCC含量为60 ％时复合材料热变形温度最高；PE-HD/MCC复合材料断口形貌分析表明MCC在基体中分布较均匀，MCC含量为60 ％时与PE-HD基体的相容性最好。

| Abstract: | High density ployethylene (PE-HI) composites filled with microcrystalline cellulose (MCC) were prepared by melt blending. The effects of MCC content on the mechanical property, rheological behavior, heat distortion temperature and surface morphology were studied. It showed that MCC improve the mechanical properties and the heat distortion temperature. The optical content of MCC was found as 60 %, which resulted in a uniform dispersion of MCC in PE-HD matrix. |
