Abstract

EPDM (etilen propilen dien
monomer) önemli bir sentetik kauçuktur ve birçok farklı sektörde önemli
miktarlarda kullanılır. Kullanım miktarındaki artışa paralel olarak EPDM atığı
ortaya çıkmaktadır. Bu tür malzemeler, çapraz bağlanmalarından dolayı tekrar
eritilip tekrar işlenme ihtimaline sahip değildir. EPDM atıkları, genellikle,
ithal bazlı plastik endüstrisi için zaten önemli bir kayıp olup yakıt olarak
tüketilmektedir. EPDM kalıntılarının değerlendirilmesinin bir başka yöntemi,
bunları küçük boyutlara getirerek farklı polimerlere eklemektir. Bu çalışmanın
amacı atık EPDM tozlarının, polipropilen EPDM karışımlarının bükülme
özellikleri üzerindeki etkisini araştırmaktır. Dört farklı boyda (0-50, 50-75,
75-150 ve 150-300µ) öğütülmüş EPDM, ekstrüzyon yoluyla dört farklı oranında %
0, % 10, % 20, % 30 ve % 50 ile polipropilene eklendi. Bu karışımlara ayrıca %
1 oranında kaydırıcı ve % 0.2 oranında antioksidan ilave edildi. Test
numuneleri bu karışımlardan enjeksiyonlu kalıplama ile hazırlandı. Standartlara
göre hazırlanan numunelere eğilme ve HDT testi yapıldı.

Effect of Addition of Recycled EPDM Size on The Bending Properties of Polypropylene

Abstract



EPDM (ethylene propylene
diene monomer) is an important synthetic rubber and is used in significant
quantities in many different sectors. In parallel with the increase in the
amount of usage, EPDM waste is emerging. Such materials do not have the
possibility of being melted and processed again due to their cross-linking.
EPDM waste is usually consumed in the form of fuel, which is already a
significant loss for the import-based plastic industry. Another method of
evaluation of EPDM residues is to add them to different polymers by bringing
them into small dimensions. The aim of this study is to investigate the effect
of waste EPDM powders on the bending properties of polypropylene EPDM mixtures.
Ground EPDM (GEPDM) with four different sizes (0-50, 50-75, 75-150 and
150-300µ) were added to polypropylene with four different weight ratios 0% 10%,
20%, 30% and 50% via extrusion method. These mixtures were also added with a 1%
slider and 0.2% antioxidant. Test samples were prepared by injection molding
from these mixtures. Bending and HDT tests were performed on the samples
prepared according to the standards.
