摘要: 本文采用聚乳酸(PLA)、木粉、聚己二酸丁二醇/对苯二甲酸酯(PBAT)，通过挤出/注塑成型制备PLA/PBAT/木粉复合材料。借助材料试验机等详细研究PLA含量对木塑复合材料力学性能(弯曲强度、拉伸强度和冲击强度)、吸水率的影响。结果表明随着PLA含量增加，木塑复合材料的弯曲性能和拉伸性能逐渐增加。当PLA含量达到66%时，与未添加PLA相比，木塑复合材料的弯曲强度和弯曲模量分别提高了95%和850%；拉伸强度仅提高了30.9%；木塑复合材料的冲击强度则随着PLA含量增加而下降。吸水试验表明PLA的加入可有效降低PBAT木塑复合材料的吸水率。
Abstract: Polylactic acid (PLA), wood flour and polybutylene adipate/terephthalate (PBAT) were used to fabricate PLA/PBAT/wood flour composites using an extrusion/injection method. The influences of PLA on the mechanical properties and water absorption of PBAT/wood flour composites were studied through material testing machine. The results showed that the flexural and ensile proper-ties of PLA/PBAT/wood flour composites increased as PLA content increased. Compared with composites without PLA, PLA/PBAT/wood flour composites were increased by 95% and 850% at 66% PLA, respectively, whereas tensile strength was only elevated by 30.9%. Impact strength of PLA/PBAT/wood flour composites decreased as PLA content decreased, which was relevant to the rigidness of PLA. In addition, water absorption of PLA/PBAT/wood flour composites was further reduced due to the addition of PLA.
