Abstract

Thermal behaviors of eucalyptus wood residue (EWR) filled recycled high density polyethylene (HDPE) composites have been measured applying the thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC). Morphology of the materials was also studied using scanning electron microscope (SEM). Addition of the EWR into the recycled HDPE matrix reduced the starting of degradation temperature. EWR filled recycled HDPE had two main decomposition peaks, one for EWR around 350 degrees C and one for recycled HDPE around 460 degrees C. Addition of EWR did not affect the melting temperature of the recycled HDPE. Morphological study showed that addition of coupling agent improved the compatibility between wood residue and recycled HDPE.

摘要

通过热重分析（TGA）和差示扫描量热法（DSC）测量了填充桉木残渣（EWR）的再生高密度聚乙烯（HDPE）复合材料的热行为。还使用扫描电子显微镜（SEM）研究了材料的形态。将EWR添加到再生HDPE基体中降低了降解温度的起始点。填充EWR的再生HDPE有两个主要分解峰，一个是EWR在350℃左右，另一个是再生HDPE在460℃左右。添加EWR不影响再生HDPE的熔点。形态学研究表明，添加偶联剂改善了木残渣与再生HDPE之间的相容性。
