添加生物炭對木材塑膠複合材料物理機械性質及耐候性質之影響
Effects of Bio-char Addition on the Physico-mechanical and Weathering Properties of Wood-Plastic Composites
摘要
本試驗利用生物炭（Bio-char）、柳桉（Shorea spp.）粒片及高密度聚乙烯（High density polyethylene, HDPE）以不同混合比製備木材塑膠複合材（Wood-plastic composite, WPC）；同時，利用萬能強度試驗機、加速耐候試驗機、色差計及傅立葉轉換紅外線光譜儀等儀器，探討添加不同比例生物炭對WPC物理機械性質及耐候性質之影響。試驗結果顯示，添加生物炭之試材具有較佳之尺寸安定性及抗濕性。而在機械性質方面，添加生物炭之試材抗彎強度及抗彎彈性模數與未添加生物炭之試材間無顯著之差異，但具有較高之內聚強度及木螺釘保持力，顯示WPC中添加生物炭可有效改善塑膠與木質材料之界面性質。在耐候性質方面，添加生物炭之試材表面顏色變化較小，且具有較高之強度保留率。綜合上述結果顯示，於木材塑膠複合材中添加生物炭可有效改善其耐候性質。

In this study, bio-char, lauan (Shorea spp.) particle and high density polyethylene (HDPE) were used as raw materials to manufacture wood-plastic composites (WPCs) with different mixture ratios. Effects of bio-char content on the physico-mechanical and weathering properties of WPCs were evaluated by universal strength testing machine, accelerated weathering tester, color difference meter and Fourier transform infrared spectroscopy, etc. The results showed that the WPCs could be improving the dimensional stability and the moisture resistance by adding the bio-char. The modulus of rupture (MOR) and modulus of elasticity (MOE) had no significant differences between WPCs with and without adding the bio-char, but the internal bond and the wood screw holding strength could be enhanced by adding the bio-char. This result indicated that the interface of plastic matrix and wood particle of WPCs could effectively improve with the addition of bio-char. Furthermore, the addition of bio-char into WPCs not only had a less change in surface color but also had the higher strength retention after accelerated weathering test. Accordingly, the weathering properties of WPCs could be effectively improved by adding the bio-char.
