| 摘 要： | 采用熔融挤出法制备了低密度聚乙烯(LDPE)/橡实壳纤维(AS)木塑复合材料.研究了增容剂聚乙烯接枝马来酸酐(PE-g-MAH)对LDPE/AS木塑复合材料的影响.结果表明,PE-g-MAH是一种优良的增容剂,当其质量分数为5%时,LDPE/AS复合材料的拉伸强度比未添加时提高77.6%,弯曲强度提高83.8%,缺口冲击强度基本保持在5.0 kJ/m2.SEM分析表明,PE-g-MAH改善了AS与LDPE基体材料的相容性.DMA和DSC测试表明,PE-g-MAH能有效改善两相之间的界面相容性,并从根本上改善LDPE基体材料的性能.

| Abstract: | The bio-composites of low density polyethylene(LDPE)/acorn shell(AS) fibre were produced by hot-melt extrusion method.The effects of PE-g-MAH on composites were studied.The results suggested that PE-g-MAH was an excellent compatibilizer for LDPE/AS composite.When the content of PE-g-MAH was 5% under the condition of 50% AS content,compared the mechanical properties of modifying composite with those of composite without compatibilizer,the tensile strength increased by 77.6%,flexural strength increased by 83.... |
