Abstract

Bu çalışmada, Nitril-Butadien
Kauçuğu (NBR)  esaslı Genel (FKK0) bir
referans kauçuk bileşiği içerisine, 
karbürize edilmiş fındık kabuğu külünden (FKK) % 0- % 10- % 15 ve % 20
oranlarında ilave edilerek, 4 faklı bileşik hazırlanmıştır. Vulkanizasyon
sonrasında bileşiklerin sertlik, yoğunluk, kopma dayanımı, kopma uzaması,
yırtılma dayanımı ve çaprazbağ yoğunlukları ölçülmüştür. Çaprazbağ yoğunluğunun
mekanik özellikler üzerine etkileri değerlendirilmiştir. Karbürize edilmiş
fındıkkabuğu külü ilave edilen bileşiklerin özellikleri, hem kendi aralarında
hem de FKK0 bileşiğiyle karşılaştırılmıştır. Karbürize edilmiş fındıkkabuğu
külü, bileşiklerin maliyetini önemli ölçüde düşürmüştür.  Artan çaprazbağ yoğunluğu ile bileşiklerin
sertliğinde artışa neden olmakla birlikte, kopma dayanımı ve kopma uzamasında
avantaj sağladığı görülmüştür. Artan fındıkkabuğu külünün yoğunluğu arttırdığı
tespit edilmiştir. Kırık yüzey morfolojilerinin belirlenmesi amacıyla,
bileşiklerin kopma yüzeyleri Taramalı Elektron Mikroskobu (SEM) ile karakterize
edilmiştir. SEM görüntüleri incelendiğinde dolgu miktarının artmasıyla kauçuk
matris içerisindeki dağılımının homojenliğin bozulduğu da görülmüştür.

Preparing and Characterizing New NBR-Based Compounds with Natural Waste Materials

Abstract

In this study, carbonized nutshell
ash (NSA) was added at ratios of 0, 10, 15, and 20 % into a general (FKK0)
nitrile- butadiene rubber (NBR) -based reference rubber compound and four
compounds were prepared. After the vulcanization, the hardness, density,
tensile strength, elongation at rupture, tear strength, and cross-link
densities of the compounds were measured. The effects of the cross-link density
on mechanical properties were evaluated. The properties of the compound with
carbonized nutshell addition were compared to each other as well as with the FKK0
compound. The carbonized nutshell ash considerably decreased the costs of the
compounds.  While the increasing
cross-link density caused an increase in hardness of the compounds, it provided
an advantage for tensile strength and elongation at rupture. It was found that
increasing nutshell ash increased the density. The compounds were characterized
by a scanning electron microscope (SEM) in order to determine the fracture
surface morphologies. When the SEM images were examined, it was observed that
as a result of increasing amount of the filler, the homogeneity of the
distribution within the rubber matrix observed.
