摘要: 本研究利用台灣二葉松(Pinus taiwanensis)木粒片、原生型高密度聚乙烯(Virgin high density polyethylene, vHDPE)、回收型高密度聚乙烯(Recycled high density polyethylene, rHDPE)、回收型低密度聚乙烯(Recycled low density polyethylene, rLDPE)、放射松(Pinus radiata)單板及乙醯化(Acetylation)單板以一次熱壓成型(One-step hot press molding)方式製備木材塑膠複合材心合板(Wood plastic composites core plywood, WPCP)。同時,利用萬能強度試驗機、色差計、針觸式表面粗糙度儀、光澤度計、全反射式傅立葉轉換紅外線光譜儀(Attenuated total reflectance–Fourier transform infrared spectroscopy, ATR–FTIR)及X-ray密度檢測儀等儀器,探討密度、塑膠種類及乙醯化單板對WPCP物理機械性質之影響。試驗結果顯示,不同密度之WPCP中,以密度800 kg/m3之WPCP較能兼具試材之尺寸安定性及機械性質之表現。此外,比較原生與回收HDPE所製備之WPCP時發現,利用回收塑膠所製備之複合材,其具有與原生塑膠製備者相似之物理機械性質。而以乙醯化單板製備之WPCP其吸水率及吸水厚度膨脹率明顯地較未處理者低,且表面抗拉強度隨乙醯化重量增加率的增加而增加。此外,戶外耐候試驗之結果顯示,乙醯化單板除能有效提高WPCP之光安定性外,亦可有效提升WPCP之MOE保留率及表面抗拉強度。另一方面,於64天戶外耐候期間,WPC之塑膠因再結晶作用而使結晶度有顯著地增加,而WPCP之塑膠結晶度則無顯著差異。綜合上述結果可以得知,單板經乙醯化處理後,能有效提升WPCP之尺寸安定性、表面抗拉強度及耐候性。
The purpose of this study is to develop and manufacture wood plastic composite core plywood (WPCP) from wood particles (Pinus taiwanensis), different kinds of plastics (including vHDPE, rHDPE and rLDPE) and untreated/acetylated veneer (Pinus radiata) by one-step hot press molding. The effect of density, plastic and acetylated veneer on physicomechanicl properties of WPCP were evaluated by universl testing machine, color difference meter, stylus-type surface profilometer, gloss meter, attenuated total reflectance-Fourier transform infrared spectroscopy (ATR-FTIR) and X-ray density profiler, etc. Results revealed that, among WPCP with various densities, 800 kg/m3 of WPCP exhibited high performance on dimensional stability and mechanicl properties. In addition, the recycled HDPE based WPCP showed the similar physicomechanicl properties to the virgin HDPE based WPCP. On the other hand, the water absorption and the thickness swelling of WPCP with acetylated veneer were lower than those of untreated WPCP. As well as the surface tensile strength of WPCP increased with increasing the weight gain of acetylated veneer. Furthermore, the results of outdoor weathering demonstrated that not only the photostability, but also the MOE retention ratio and surface tensile strength of WPCP with acetylated veneer were significantly higher than those of WPCP with untreated veneer. Moreover, the rHDPE crystallinity of WPC was significantly increased, while the rHDPE crystallinity of WPCP was not significantly different during 64 days of outdoor weathering. Accordingly, it concludes that better dimensional stability, surface tensile strength and weathering properties could be achieved when the WPCP made by the acetylated veneer.
