摘要
以高密度聚乙烯(HDPE)和木粉为原料制备了木塑复合材料。研究了木粉、相容剂含量对木塑复合材料力学性能、流变性能及微观结构的影响。结果表明:木粉含量的增加,可提高复合材料的刚性、熔体黏度以及剪切敏感性,但韧性有所降低;而添加适量的相容剂改善了复合材料的界面微观结构,从而改善了木塑复合材料的力学性能,而且还在一定程度上改善了复合材料的加工流动性。
Wood-plastic composites were prepared with HDPE and wood flour as raw material. The effects of wood content and compatibilizer content on mechanical properties, rheological properties and microstructure of wood-plastic composites were investigated. The results indicated that rigidity, melt viscosity and shear sensitivity of the composites were increased with increasing wood content, but toughness of the composites was decreased. The compatibilizer enhanced interface microstructure, mechanical properties and processing flowahility of wood-plastic composites.
