Influence of EVA Content on the Properties of Extrusion Molding WPCS

Abstract:

EVA was tried to improve the compatibility between wood flour and plastics substrate as a new kind of coupling agent. Infrared diffuse reflectance spectroscopy was applied to examine the changes in surface groups. The influence of the EVA content on the mechanical properties of WPCs was investigated and the morphologies of fractured surfaces were examined using a scanning electron microscope (SEM). Infrared diffuse reflectance spectroscopy shows that the EVA reduced the polarity of the wood flour. When the content of EVA is increased the mechanical properties of WPCs also increased. The SEM showed that EVA can help improve the interface compatibility between the fiber and plastic by aiding in the bonding of more plastic to the wood fiber. The comprehensive performance of the WPCs reached its maximum potential when the EVA level was at 15%.
