摘要
以PP和HDPE的混合物为塑料基体,EPDM为增韧剂,木粉为填料,采用挤出成型法制备了PP/PE基木塑复合材料(WPC),研究了配方中PP/PE比例、EPDM加入量变化对WPC力学性能的影响.结果表明:随着WPC中PP质量分数的增加,WPC的弯曲模量增加,但弯曲强度和冲击强度均出现先减小后增大的现象;随着塑料基体中EPDM加入量增加,WPC的冲击强度增加,但其弯曲强度和弯曲模量降低.
Wood-plastic composite （WPC） based on PP/PE were prepared by extrusion with PP and HDPE blends as plastic matrix, EPDM as toughening agents, wood flour as filler. The paper researched on the effects of PP/PE and EPDM content on the mechanical properties of WPC. The results showed that with PP content increased in the plastic matrix, the flexural modulus of WPC increased, but the flexural strength and impact strength were decreased first and then increased. With EPDM content increased in the plastic matrix, the impact strength of WPC increased, the flexural strength and flexural modulus decreased.
