Abstract

Bu araştırmada çevreyi kirleten atık maskeler (WM) polyester kompozit içerisinde değerlendirilmiştir. Elde edilen kompozitin bazı fiziksel ve kimyasal özellikleri karakterize edilmiştir. Özellikle yoğunluğu, Shore D sertliği, ısıl iletkenlik katsayısı, ısıl kararlılığı ve gözenekliliği karşılaştırılarak belirlenmiştir. Atık maskeleri toplanır, dezenfekte edilir, öğütülür, kurutulur ve dolgu maddesi olarak ağırlıkça % 0, % 2, % 5, % 7 ve % 10 oranlarında doymamış polyestere (UP) eklenir. Maske atıkları doymamış polyestere belirli oranlarda ilave edilerek 1000 rpm karıştırma hızında 10 dakika boyunca iyice homojenize edilir. Daha sonra metil etil keton peroksit (MEKP) ve kobalt oktoat (Co. Oc.) katalizörleri yardımıyla kimyasal reaksiyon gerçekleştirilmiştir. Üretilen polyester kompozitlerin kimyasal bağ yapısı Fourier dönüşümlü kızılötesi spektroskopisi (FTIR) ile belirlenir. Elde edilen sonuçlara göre kompozitlerdeki WM oranları arttıkça kompozitlerin hem yoğunluğu hem de Shore D sertliği azalmıştır. Artan WM oranı ile polyester kompozitin mekanik mukavemetinin ve gözenekliliğinin arttığı tespit edilmiştir. Polyester kompozitte kütlece WM'deki artış, termal iletkenlik katsayısını ve aktivasyon enerjisini arttırır.

PRODUCTION AND CHARACTERIZATION OF WASTE MASK REINFORCED POLYESTER COMPOSITE

Abstract

In this research, waste masks (WM) that pollute the environment have been evaluated in the polyester composite. Some physical and chemical properties of the obtained composite have been characterized. In particular, its density, Shore D hardness, thermal conductivity, thermal stability, and porosity have been determined. Waste masks were collected, disinfect, ground, dried and added into unsaturated polyester (UP) at the rates of 0 %, 2 %, 5 %, 7 %, and 10 % by mass as a filler. Mask wastes were reinforced to the unsaturated polyester in certain proportions and were homogenized thoroughly for 10 minutes at a mixing speed of 1000 rpm. Then, the chemical reaction has been carried out with the help of methyl ethyl ketone peroxide (MEKP) and cobalt octoate (Co Oc) catalysts. The chemical bond structure of the produced polyester composites was determined by Fourier transform infrared spectrophotometer (FTIR). According to the results, both density and Shore D hardness of the composites decreased as the WM ratios in the composites increased. It has been evaluated that the mechanical strength of the polyester composite and porosity raises with increasing WM ratio. The increase in WM by mass in the polyester composite raises thermal conductivity and activation energy.
