Abstract

In this study, micronized-ethylene-propylene-diene monomer powders (m-EPDM) by the physical crushing method were added to EPDM rubber, and their effects on physical and mechanical properties were examined. Micronized EPDM powders were added at rates of 10-20-30%. EPDM rubber was pulped with micronized EPDM powder using a 1.5-liter laboratory type mini banbury. The obtained paste was vulcanized in the press at 180 °C for 20 min., and test plates were acquired. Rheological and fluidity properties of EPDM rubber with m-EPDM powder added were examined by pre-press rheometer (Moving Die Rheometer_MDR) and Mooney viscosity tests. Tensile and permanent deformation tests were performed to determine mechanical properties density, Shore A hardness tests were performed to determine physical properties and dispersion analysis was performed to distribute the additives in EPDM rubber. As a result of the study, minimum torque (ML) values increased while maximum torque (MH) values decreased depending on the amount of m-EPDM. Mooney viscosity of EPDM/30m-EPDM rubber increased by 40.9%. It was observed that cure rate index (CRI) did not change depending on the amount of m-EPDM. With the addition of 30% m-EPDM, breaking strength decreased by 39.2%, and elongation at break was reduced by 9.87%.

Abstract

Bu çalışmada fiziksel kırma yöntemiyle mikronize edilmiş EPDM (m-EPDM) tozları farklı oranlarda EPDM kauçuğuna ilave edilerek fiziksel ve mekanik özelliklere etkisi incelenmiştir. Mikronize EPDM tozları %10-20-30 oranlarında ilave edilmiştir. 1.5 lt’lik laboratuvar tipi mini banbury kullanılarak mikronize-EPDM tozu ile EPDM kauçuğu hamur haline getirilmiştir. Elde edilen hamur preste 180 oC ve 20 dakika boyunca vulkanize edilerek test plakaları elde edilmiştir. Pres öncesi reometri (MDR) ve Mooney viskozite testleri ile m-EPDM tozu ilaveli EPDM kauçuğun reolojik ve akışkanlık özellikleri incelenmiştir. Mekanik özelliklerin belirlenmesi için çekme testi ve kalıcı deformasyon testi, fiziksel özelliklerin belirlenmesi için yoğunluk ve Shore A sertlik testleri, EPDM kauçuğunda mevcut olan katkıların dağılımı için ise dispersiyon analizi yapılmıştır. Çalışma sonucunda, m-EPDM miktarına bağlı olarak minimum tork (ML) değerleri artarken maksimum tork (MH) değerleri azalmıştır. EPDM/30m-EPDM kauçuğun mooney viskozitesi %40,9 oranında artmıştır. CRI oranlarının, m-EPDM miktarına bağlı olarak değişmediği gözlenmiştir. %30 m-EPDM ilavesi ile kopma mukavemeti %39.2, kopma uzaması ise %9.87 oranlarında azalmıştır.
