摘要

研究了未经处理和碱处理的橡胶木粉（RWF）对木塑复合材料（WPCs）吸水、拉伸和弯曲性能的影响。用浓度为2%w/v的NaOH溶液对RWF表面进行碱处理24小时。结果表明，碱处理的RWF可以增强与rPP的界面粘附性，并改善WPCs的吸水性、拉伸和弯曲性能。此外，碱处理和RWF含量显著影响拉伸和弯曲强度。碱处理还提高了WPCs的耐水性，当RWF含量为20%时，其吸水率较低（2.04%）。当RWF浓度为30wt%时，WPCs的拉伸强度（17.75MPa）和弯曲强度（35.73MPa）最高。此外，WPCs的拉伸和弯曲模量随着RWF含量的增加而增加（20%-50%）。

A comparison on untreated and alkaline treated rubberwood flour on physical and mechanical properties of wood plastic composites

The effect of the untreated and alkaline treated rubberwood flour (RWF) on water absorption, tensile and flexural properties of the wood plastic composites (WPCs) was investigated. The surface of RWF was treated by an alkaline treatment with NaOH solution of 2% w/v concentration for 24 h. The results showed that the RWF treated with alkaline could enhance the interfacial adhesion with rPP and also improve the water absorption and tensile and flexural properties of WPCs. In addition, the alkaline treatment and RWF content significantly affected the tensile and flexural strength. The alkaline treatment also increased water resistance of WPCs, which at 20% RWF content showed the lower water absorption (2.04%). The highest tensile strength (17.75 MPa) and flexural strength (35.73 MPa) of WPCs were achieved with an alkaline treatment at 30 wt% RWF. Moreover, the tensile and flexural modulus of WPCs increased with increasing RWF content (20% to 50%).
