摘要：

為能提升煉鋼廠水淬爐石（slag）的實用價值，本研究進行爐石作為聚丙烯塑膠添加劑的評估。實驗結果顯示爐石的添加，將提升材料的彎曲強度、耐衝擊強度和拉力、彎曲模數。爐石的補強效果，介於滑石粉與碳酸丐粉之間。粒徑小者（約10μm）具有較佳機械性質，教室當的爐石添加量為30~40wt%。另外， 從電子顯微鏡的觀察得知爐石粉與基材的界面接著不佳，但可經偶合劑如LZ44的處理來改善，同時改善後之材料在耐衝擊強度方面有顯著的增加。

Material Properties of Slag-Filled Polypropylene

Abstract：

As an effort to promote the added value of slag, which is an industrial waste from the ironmaking process, a feasibility study for using slag as a filler in polypropylene was conducted. Experimental results revealed that addition of slag could improve the flexu-ral strength, impact strength, tensile modulus and flexural modulus of polypropylene. The reinforcing effect is between that of talc and that of calcium carbonate. Material with slag particles of around 10 m exhibits better mechanical properties. The proper amount of slag added in polypropylene is about 30 ~ 40wt%. Furthermore, the interfa-cial adhesion between slag and polymer matrix was found poor from the observation of a scanning electron microscope. The situation could be improved by treating slag with coupling agents such as LZ44. After treatment with LZ44, the resulting material shows higher impact strength than the untreated.
