Abstract

Bu çalışmada lignoselülozik dolgu maddesi olarak atık gazete kâğıdı lifi, bitkisel atık yağ kullanılmış, polimer olarak da geri dönüştürülmüş polipropilen kullanılmıştır. Atık gazete kâğıdı öğütülüp ve yaklaşık 24 saat boyunca 60˚C˚'de kurutma fırınında bekletildikten sonra %10, %20 ve %30 oranlarında geri dönüştürülmüş polipropilen ile karıştırılmıştır. Atık bitkisel yağ ise %2.5 oranında ilave edilmiştir. Karışımlar 170°C,175°C,180°C,185°C ısı kademelerinde ayarlanmış olan ekstrüzyon makinasına konulmuştur. Ekstrüzyon yöntemiyle üretilen kompozitlerin mekanik ve termal özellikleri belirlenmiştir. Atık gazete kağıdı lifi oranının ilkin eğilme mukavemetini azalttığı, daha sonra ise arttırdığı gözlenmiştir. Termal özelliklerde atık bitkisel yağ kullanımının olumlu etkisi olup ısıl direnci arttırmıştır. DSC analiz sonuçları incelendiğinde, atık gazete kağıdı lifinin kristalenliği arttırdığı sonucuna varılmıştır. Bu çalışma ile tümüyle atık olan bileşenlerin kompozit üretiminde kullanılabilir olduğu ve vaks gibi atık bitkisel yağların kullanılabileceği sonucuna ulaşılmıştır.

Evaluation of Vegetable Waste Oil and Old Newspaper Fibers in Waste Polypropylene Composites

Abstract

In this study, old newspaper fiber and waste vegetable oil were used as lignocellulosic filler, and recycled polypropylene was used as polymer. The old newspaper was ground and kept in the drying oven at 60˚C˚ for about 24 hours, then mixed with recycled polypropylene at 10%, 20% and 30% ratios. Waste vegetable oil was added at the rate of 2.5%. The mixtures were put into the extruder, which was set at temperatures of 170 C°,175 C°,180 C°,185 C°. The mechanical and thermal properties of the composites produced by the extrusion method were determined. It was observed that the ratio of the old newspaper fiber first decreased the flexural strength and then increased it. The use of waste vegetable oil has a positive effect on thermal properties and has increased thermal resistance. When the DSC analysis results were examined, it was concluded that the old newspaper fiber increased the crystallinity. With this study, it was concluded that completely waste components can be used in composite production and waste vegetable oils such as wax can be used.
