摘要：木塑復合材料具有比單獨的木質材料或塑料產品更優異的性質，是木材理想的替代品，它的出現可減少廢棄木材和塑料對城市環境的污染，也適應現代材料復合化發展的規律[1]。而聚氯乙烯/木粉復合材料是在聚氯乙烯塑料原料中添加30-50%的木質纖維填料（木粉）和各種加工助劑如穩定劑、改性劑、潤滑劑、偶聯劑等，利用擠出、注塑或模壓成型的方法制備成木塑板材。其關鍵技術是保證木質物料較高的填充量，以達到制品有較低的生產成本和較高的使用性能。本文主要是通過模壓成型的方法對聚氯乙烯/木粉木塑復合材料進行了研究,分析了木粉的不同填充量對復合材料吸水性能、硬度、拉伸強度及斷裂伸長率的影響。由實驗結果可知:當木粉含量為40份時,復合材料的綜合性能較好。

Wood flour content on the PVC / wood flour composite materials impact

Abstract：Wood-plastic composite materials are more separate wood or plastic products superior nature, is an ideal substitute for wood, it can reduce the appearance of scrap wood and plastic pollution of the urban environment, but also adapt to modern composite materials of the development of the law. And PVC / wood flour composite material is added to 30-50% of the wood fiber filler (wood powder) and various processing aids in the PVC plastic materials such as stabilizing agent, modifiers, lubricants, coupling agent, and so on, using extrusion, injection molding or the method of wood-plastic-sheet. The key technology is the guarantee of wood materials high filler content, products have to meet the lower production cost and higher performance. This paper mainly studied the PVC / wood flour composite material by the molding method, analyzed the different wood flour-filled volume of the composite material can be absorbent, hardness, tensile strength and elongation at break of affected. The experimental results indicate that: When the content of wood powder 40, the comprehensive performance of composite material better.
