Effects of Coupling Agents on the Physical Properties of Wood Flour/Polyethylene/Clay Composites |
| 초록 |
Wood flour/polyethylene (PE)/clay composites were prepared by melt blending followed by compression molding. In this study, a wood flour/PE/clay composite was made from selected conifers wood flour, PE and a type of organoclay together with a coupling agent, maleic anhydride polyethylene copolymer (MAPE). The effects of five different coupling agents on the physical properties of the woodpolymer composites (WPCs) were investigated via testing the WPCs with different coupling agents respectively. The WPCs were blended in a melt mixer equipped with a roller blades rotor at different mixing conditions (140℃~160℃, 60 rpm, 15 min). The physical properties of the WPCs were measured by UTM, izod impact tester, DSC, TGA and DMA. The MAPE with a high melt flow index and low maleic anhydride contents were preferred to improve the physical properties of the WPC. The backbone structure of the MAPE also affected the physical properties of the WPC. |
