摘要


本實驗係探討稀土金屬氧化物-氧化釔對聚丙烯基材之性質影響,以融熔混煉的方式混成不同比例的摻混物。此實驗除了製備未改質之氧化釔複合材料外,另外也探討經含6-胺基酸之鈉鹽表面改質的氧化釔複合材料及相容劑(PP-g-MA)之氧化釔複合材料。 經由傅立葉轉換紅外線光譜分析儀(FTIR)分析得知氧化釔的表面改質是成功的。在燃燒性質方面則是利用限氧指數儀觀察複合材料之阻燃效果。在熱學性質方面,利用熱重損失分析儀(TGA)觀察各複合材料之熱穩定性及剩餘質量。偏光顯微鏡(POM)與掃描式電子顯微鏡(SEM)來觀察複材的分散情形與截面型態。 結果發現添加3%之經改質的氧化釔複材能有效提升限氧指數,且根據TGA熱分析結果指出經表面改質的氧化釔複合材料能提升剩餘質量,且與裂解速率的下降與阻燃結果之提升相互呼應。

In this study, we will investigate the properties of polypropylene composites by adding rare earth oxide-yttrium oxide. This study is to prepare polypropylene/yttrium oxide composites with various ratios by melt-blending. In addition to fabrication of unmodified yttrium oxide/polypropylene composites, we treated yttrium oxide with a sodium sult of 6-aminocaproic acid to modify the surface of yttrium oxide. We also added polypropylene grafting maleic anhydride to polypropylene/yttrium oxide composites. The structure of yttrium oxide was modified by a sodium sult of 6-aminocaproic acid successfully as observed in FTIR. The combustion properties and the flame retardancy of the composites were analyzed by testing of limit oxygen index (LOI) to obtain oxygen index. The thermal properties including the degradation temperature and residue mass of the composites were analyzed by thermogravimetric analysis (TGA). The morphology of the composites were observed by polarizing microscope (POM) and scanning electron microscopy (SEM). The limit oxygen index of the composites was effectively increased by adding 3% modified yttrium oxide, and the residue mass of the composites was also increased as observed in the TGA results. The result of degradation rate was also decreased by adding modified yttrium oxide.
