Bu çalışmada, atık lignoselülozik maddelerle üretilen odunplastik kompozitlerin termal özellikleri ve yangına karşı dirençleriaraştırılmıştır. Bu amaç için lignoselülozik atıklar, yüksek yoğunluklupolietilen (YYPE), sodyum borat (boraks) ve borik asit kullanılmıştır. Kompozitmalzemesinin üretimi aşamasında çift vida ekstruder kullanılmıştır. Elde edilengranül malzeme 175 °C’de preste preslenerek levha haline getirilmiştir. Yapılantestlertde farklı oranlarda odun plastik kompozitlere eklenen borik asit veboraks maddelerinin termal gravimetrik analiz (TGA), yatay yanma ve limitoksijen indeks (LOI) sonuçları üzerine etkileri araştırılmıştır. Elde edilensonuçlara göre borlu bileşiklerin miktarı arttıkça kompozit malzemede bulunanlignoselüloziklerin ve plastik malzemenin yanma derecelerinin (°C) yükseldiği anlaşılmıştır.Ayrıca kompozitlere eklenen borlu madde miktarı arttıkça yatay yanma hızınındüştüğü anlaşılmıştır.

In this study, the thermal properties and fire resistancesof the wood plastic composites produced with waste lignocellulosic materialswere investigated. For this purpose, lignocellulosic waste, high densitypolyethylene, (HDPE) sodium borate (borax) and boric acid was used to producethe wood-plastic composites. A twin-screw extruder was used during theproduction of the wood plastic composites. The produced composite granule waspressed at 175 °C hot press. The effects of boric acid and borax added to woodplastic composites were investigated with the thermal gravimetric analysis(TGA), the horizontal burning rate and the limiting oxygen index (LOI).According to the results, it was understood that as the amount of the boroncompounds was increased, the burning degree (°C) of the composite materialincreased. Furthermore, the using of the boric acid and sodium borate in theproduction of the wood plastic composite decreased burning speed.
