中文摘要 | 本文主要目的是研究添加不同含量1、2、3及4 wt%之雲母於聚苯乙烯中,利用捏合機及押出機混煉,製備成聚苯乙烯奈米複合材料(聚苯乙烯 /雲母),探討在不同的雲母添加量下之奈米複合材料的熱性質及機械性質,並與純聚苯乙烯之數據相互比對。 研究結果顯示,聚苯乙烯/雲母於3 wt%時其熱裂解溫度提升28℃,其玻璃轉移溫度與熱變形溫度則無顯著的變化;熱傳導係數及熔融指數皆隨雲母添加量之增加而增加。在機械性質中,添加雲母能提升其拉伸與彎曲強度,尤其在2 wt%之雲母時拉伸強度可提高將近35%最為顯著;而衝擊能量、耐磨耗及硬度則呈現下降情況。 由本研究結果得知,只需添加適量的雲母,就可以有效的改善聚苯乙烯的物性。 |
英文摘要 | The main purpose of this paper is to study different content with 1, 2, 3 and 4 wt% of mica in polystyrene using kneader machines and extrusion machines mixing and creating nanocomposites of polystyrene (PS / mica). Exploring the thermal and mechanical properties of nanocomposites with different amount of mica added, then mutually comparing with the data of pure polystyrene. The results showed that the polystyrene / mica corresponding to 3 wt% have upgraded its pyrolysis temperature to 28℃, whereas the transition temperature and heat distortion temperature of glass had no significant change; the thermal conductivity and melt index both increased with the increasing of the mica content. In mechanical properties, adding mica can improve the tensile and flexural strength. Especially for the condition of 2 wt% of mica, the tensile strength can be increased by nearly significant 35 percent; while the impact energy, wear and hardness showed decreasing circumstances. The results from this study showed that, by merely adding the adequate amount of mica can we effectively improve the physical properties of polystyrene. |
