Increase in energy consumption and environmental pollution are some of the main problems of today. One of the ways to overcome these problems is to increase the use of recycled materials. Heat and sound insulation in buildings can play an important role in saving energy and reducing environmental pollution with composite materials made from recycled leather. This study investigates the possibility of reusing leather scraps. Composite material was produced by cutting leather waste for thermal and sound insulation of buildings into small pieces and pressing them in a mechanical mold using polyvinyl acetate binder. The effect of the thickness of the developed new leather-added composite materials on their thermal and acoustic insulation properties was examined. When the thermal and acoustic properties of the composites were evaluated, it was determined that the PVA/skin thicknesses forming the mixture varied depending on the mean temperature and frequency (Hz). As a result of the measurements, it was seen that the sound at the 3000 Hz frequency, to which the human ear is most sensitive, was absorbed by 61%.

Çevre Dostu, Geri Dönüştürülebilir, Deri Takviyeli Kompozit: Isı ve Akustik Özellikleri

Öz

Enerji tüketimindeki artış ve çevre kirliliği, günümüzün temel sorunlarından bazılarıdır. Bu sorunların üstesinden gelmenin yolarından biri de geri dönüştürülmüş malzeme kullanımını artırmaktır. Binalarda ısı ve ses yalıtımı, geri dönüştürülmüş deriden yapılan kompozit malzemeler ile enerji tasarrufunda ve çevre kirliliğinin azaltılmasında önemli bir rol oynayabilir. Bu çalışma, deri artıklarının yeniden kullanılma olasılığını araştırmaktadır. Binaların termal ve ses yalıtımına yönelik deri atıklarını küçük parçalar haline getirip polivinil asetat bağlayıcı kullanarak mekanik bir kalıpta preslenmesiyle kompozit malzeme üretimi yapılmıştır. Geliştirilen yeni deri katkılı kompozit malzemelerin kalınlıklarının termal ve akustik izolasyon özelliklerine etkisi incelenmiştir. Kompozitlerin termal ve akustik özellikleri değerlendirildiğinde karışımı oluşturan PVA/deri kalınlıklarının, mean temparature ve frequency (Hz) bağlı olarak değiştiği belirlenmiştir. Ölçümler sonucunda insan kulağının en hassas olduğu 3000 Hz frekanstaki sesin %61 oranında absorblandığı görülmüştür.
