Office of Research and Development
As an effort to promote the added value of slag, which is an industrial waste fromthe ironmaking process, a feasibility study for using slag as a filler in polypropylene wasconducted. Experimental results revealed that addition of slag could improve the flexural strength, impact strength, tensile modulus and flexural modulus of polypropylene.The reinforcing effect is between that of talc and that of calcium carbonate. Materialwith slag particles of around 10 nm exhibits better mechanical properties. The properamount of slag added in polypropylene is about 30 ~ 40wt. Furthermore, the interfacial adhesion between slag and polymer matrix was found poor from the observation ofa scanning electron microscope. The situation could be improved by treating slag withcoupling agents such as LZ44. After treatment with LZ44, the resulting material showshigher impact strength than the untreated.
