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.
