摘要

本研究主要探討不同粒片含水率、熱板溫度以及耦合劑或黏附劑添加量，對於平壓式木質粒片－高密度聚乙烯複合材（Wood particle-HDPE composites, WPHC）理學與機械性質之影響。試驗結果顯示，以粒片含水率4%以及熱板溫度為180℃所製備之複合材，具有較佳之木螺釘保持力與內聚強度。另外，添加耦合劑（MAPE）之木質粒片－高密度聚乙烯複合材，其抗彎強度及抗彎彈性模數隨耦合劑添加量的增加而降低，而內聚強度與木螺釘保持力則無顯著差異。至於添加黏附劑，雖可提高複合材之抗濕性，但其抗彎強度、抗彎彈性模數與木螺釘保持力卻隨著添加量增加而降低。由此顯示，添加耦合劑或黏附劑無法提升平壓式木質粒片－高密度聚乙烯複合材之機械性質。

The effects of moisture content of particle, hot plate temperature, coupling agent, or stick agent on the physical and mechanical properties of wood particle-HDPE composites (WPHC) by flat-platen pressing were investigated in this study. The results demonstrated that the WPHC exhibited good wood screw holding strength and internal bonding strength when the moisture content of particle and the hot plate temperature were 4% and 180 ℃, respectively. Furthermore, the MOR and MOE of WPHC decreased with increasing the content of coupling agent (MAPE), but that effect on the internal bonding strength and wood screw holding strength showed no significant differences. In addition, although the water absorption resistance of WPHC was improved by adding the stick agent, the MOR, MOE and wood screw holding strength of WPHC were decreased with the addition of stick agent. Accordingly, the mechanical properties of WPHC could not be improved by the addition of coupling agent or stick agent in the flat-platen hot press.
