Abstract

Increasing environmental problems today have led to the preference for organic-based biodegradable materials instead of petroleum-derived materials, which are frequently used in the industry. For this reason, composites doped with natural fibers such as hemp, flax and jute are prepared to increase the mechanical strength of polymers with low strength. Within the scope of the study, the production and use of hemp-added composite (flooring) material for recycling end-of-life waste tires, the main ingredient of which is rubber, was investigated. For this purpose, hemp-added composite products were prepared by mixing granulated rubber tires with 90-125-250 μm hemp tow binder material in the ratios of 10% and 20%. As the final product, it is aimed to obtain a green product containing hemp. It is a nature-friendly, environmentally friendly, hemp-added flooring material that is not harmful to health and the environment, in areas open to human use such as recreation areas. As a result of the analyses carried out to investigate the potential to be used as an adhesive, 10% and 20% hemp-added composite samples with 90 μm particle size showed similar and superior properties to raw rubber. In addition to obtaining an environmentally friendly floor covering material that reduces carbon emissions, the composite material produced also provides cost savings by reducing the binder ratio used by the manufacturer as a binding agent.

Atık Lastiklerin Geri Dönüşümü İçin Kenevir Katkılı Yeşil Kompozit Üretiminin Araştırılması

Abstract

Günümüzde artan çevre sorunları, endüstride sıklıkla kullanılan petrol türevli malzemelerin yerine, organik temelli biyo-bozunur malzemelerin tercih edilmesine neden olmuştur. Bu nedenle mukavemeti düşük olan polimerlerin mekanik dayanımını artırmak için kenevir, keten, jüt gibi doğal liflerle katkılandırılmış kompozitler hazırlanmaktadır. Çalışma kapsamında, ana maddesi kauçuk olan ömrünü tamamlamış atık lastiklerin (ÖTL) geri dönüşümü için kenevir katkılı kompozit (zemin kaplama) malzeme üretimi ve kullanımı incelenmiştir. Bu amaçla, granül hale getirilmiş kauçuk lastikler ile %10 ve % 20 oranlarda olacak şekilde 90-125-250 μm kenevir kıtığı birleştirici malzeme binder ile karıştırılarak kenevir katkılı kompozit ürünler hazırlanmıştır. Son ürün olarak kenevir içerikli yeşil ürün elde edilmesi, sağlığa ve çevreye zararlı olmayan, doğa dostu, karbon salınımının azaltılmasını destekleyen kenevir katkılı zemin kaplama malzemesi olarak kullanım potansiyelinin araştırılması amacıyla yapılan analizler sonucunda 90 μm partikül boyutu olan % 10 ve % 20 kenevir katkılı kompozit numuneler ham kauçuk ile benzer ve üstün özellikler göstermiştir. Üretilen kompozit malzeme ile çevre dostu, karbon salınımını azaltan bir zemin kaplama malzemesi elde edilmesinin yanı sıra üreticinin bağlayıcı ajan olarak kullandığı binder oranı düşürülerek maliyet açısından da kazanç sağlanmıştır.
