Abstract

Abstract

Aim of study: This study compared
the effects of boron-based fire retardants and synergistic influential compounds
used in medium-density fiberboard waste (MDFw) filled high-density polyethylene
(HDPE) composites.

Area of study: To improve the use
of boron based and fire retardant materials in wood plastic composite.

Material and Methods: Fiber waste, HDPE
and  boron- based compounds were used to
produce wood plastic composites. Mechanical thermal and fire properties of the
produced composites were investigated.

Main results: When fire retardants were used in composites, the
mechanical properties of composite with MAPE increased slightly, also the
modulus of elasticity of composites increased considerably. Boron-based fire
retardants and other synergistic influential compounds decreased the burning
rate and limiting oxygen index (LOI) properties of the composites.

Research highlights: The use of the zinc
borate in the MDFw-based wood plastic composite had the best results on the
mechanical and fire-retardant properties.

Geri Dönüşüm Liflerinin Kullanıldığı Odun Plastik Kompozitlerin Yangın, Termal ve Mekanik Özellikleri Üzerine Yangın Geciktiricilerin Etkileri

Abstract

Özet

Çalışmanın amacı: Bu çalışmada
lifsel atıklar ile üretilen odun plastik kompozitlerde bor esaslı (Borik asit,
boraks ve çinko borat) yangın geciktiriciler ve sinerjik etkili bileşiklerin
(antimon trioksit, amonyum fosfat ve magnezyum hidroksit)  etkileri araştırıldı. Bu çalışmada,
kompozitlerin üretilmesinde orta yoğunluklu lif levhaların (MDF) atıkları ve
yüksek yoğunluklu polietilen (YYPE) plastik hammadde kullanılmıştır.

Çalışma alanı: odun plastik kompozitlerin yangına karşı direncinin
geliştirilmesi.

Materyal ve Yöntem:
Odun
plastik kompozitlerin üretilmesi için lifsel atıklar, HDPE ve bor esaslı
bileşikler kullanıldı. Kompozitlerin üretilmesi için çift vida ekstruder
kullanıldı.Üretilen kompozitlerin mekanik termal ve yangın özellikleri
araştırıldı.

Sonuçlar: Bu amaçla farklı
bor esaslı maddeler, sinerjik etkili bileşikler ve maleik anhidrit muamele
edilmiş polietilen (MAPE) ile üretilen kompozitlerin yangın, termal ve mekanik
özelliklerine olan etkisi incelendi. Elde edilen sonuçlara göre yangın
geciktiricilerin ve MAPE’nin birlikte kullanıldığı kompozitlerin eğilme ve
çekme dirençlerinin yanı sıra kompozitlerin elastikiyet modülleri belirgin
şekilde arttığı anlaşılmıştır. Bor esaslı yanma geciktiriciler ve diğer
sinerjik etkili bileşikler, kompozitlerin yatay yanma hızını düşürdüğü ve
oksijen endeksi (LOI) özelliklerini geliştirdiği anlaşılmıştır.

Araştırma
vurguları: Çinko
boratın MDF atıkları ile hazırlanmış odun plastik kompozitlerde kullanılması,
mekanik ve yangın geciktirici özellikleri açısından en iyi sonuçları verdiği
anlaşılmıştır.
