Abstract

This work was aimed to develop green composite materials from nanocellulose / Ethylene Propylene Diene Monomer (EPDM) rubber. The obtained green composites were investigated in terms of chemical, thermal, mechanical, morphological, and aging properties. The results obtained in this work showed that the tensile strength and elasticity of the composites decreased with nanocellulose while permanent set values increased. Green composite materials have lower scorch values that means easier and faster vulcanization. Some cracks and staining were seen after 250h aging over 3 phr of nanocellulose whereas the surfaces were not degraded up to 100h weathering. All values are in the range of acceptable limits except for tear strength. Briefly, the study conducted reveals that nanocellulose can be used with EPDM until the concentration of 10.0 phr without any chemical degradation. Thus, sealing profiles used in automotive sector can be produced by nanocellulose/EPDM green composites instead of EPDM rubber. This can be an innovative technology in order to replace petroleum-based materials with bio-degradable materials.

Özet

Bu çalışmanın amacı nanoselüloz / Etilen Propilen Dien Monomer (EPDM) kauçuktan yeşil kompozit malzemeler geliştirmektir. Elde edilen yeşil kompozitler kimyasal, termal, mekanik, morfolojik ve yaşlanma özellikleri açısından incelenmiştir. Bu çalışmada elde edilen sonuçlar, nanoselülozun eklenmesi ile kompozitlerin çekme dayanımı ve elastikiyetleri azalırken, kalıcı deformasyon değerlerinin arttığını göstermektedir. Yeşil kompozit malzemeler daha düşük scorch değerlerine sahiptir, bu da daha kolay ve daha hızlı vulkanize olacakları anlamına gelir. EPDM plakaların yüzeyleri 100 saatlik yaşlanmaya kadar bozulmazken, 250 saat yaşlandırıldıktan sonra 3 phr üzerinde nanoselüloz eklenen plakaların yüzeyinde bazı çatlaklar ve lekelenmeler gözlenmiştir. Yırtılma mukavemeti dışında tüm değerler kabul edilebilir sınırlar aralığındadır. Kısaca yapılan çalışma, nanoselülozun herhangi bir kimyasal bozulma olmaksızın 10.0 phr konsantrasyonuna kadar EPDM ile kullanılabileceğini ortaya koymaktadır. Böylelikle otomotiv sektöründe kullanılan sızdırmazlık profilleri EPDM kauçuk yerine nanoselüloz / EPDM yeşil kompozitler ile üretilebilmektedir. Bu, petrol bazlı malzemeleri biyolojik olarak parçalanabilen malzemelerle değiştirmek için yenilikçi bir teknoloji olması açısından önemlidir.
