Saponin kullanımının PP esaslı odun-plastik kompozitlerin fiziksel, mekanik ve yanma özellikleri üzerine etkisi

Abstract

Bu çalışmada şişen alev geciktirici ve odun ununun kompozit malzemelerin fiziksel, mekanik ve yanma özellikleri üzerine etkisi araştırılmıştır. Şişen alev geciktirici olarak saponin (SP), amonyum polifosfat (APP) ve pentaeritritol (PER) kullanılmıştır. Üretimlerde odun unu %0-10, APP %0-18 ve PER %0-6 oranında kullanılmıştır. SP’nin kompozit malzemenin fiziksel, mekanik ve yanma özellikleri üzerine etkisini belirlemek amacıyla %0-2-4-6-8 oranında kullanılmıştır. Toplamda 20 farklı kombinasyonda kompozit malzeme üretimi yapılmıştır. Üretimi yapılan kompozitlerin yoğunluk değeri, çekme direnci (ÇD), çekme elastikiyet modülü (ÇM), kopmada uzama (KU), eğilme direnci (ED), eğilmede elastikiyet modülü (EM), darbe direnci (DD), yatay yanma ve limit oksijen indeksi (LOI) değerleri tespit edilmiştir. Test sonuçlarına göre odun unu, APP/PER ve SP ilavesi ile çekme direncinde ve kopmada uzama değerlerinde azalma görülürkençekme elastikiyet modülü, eğilme direnci, eğilmede elastikiyet modülü vedarbe direncinde değerlerinde artışmeydana gelmiştir. Dolgu maddelerinin ilavesi ile örneklerin yoğunluklarında artış tespit edilmiştir. Kompozit malzemelere APP/PER ilave edilmesi yanma özelliklerini iyileştirmiştir. Yatay yanma testinde APP/PER katkılı örneklerde alev ilerleme yapmamış ve sönmüştür. SP kullanım oranının artması ile yanma hızında düşme ve LOI değerinde artış tespit edilmiştir.

Effect of saponin usage on physical, mechanical and fire properties of PP based wood-plastic composites

Abstract

In this study, the effects of intumescent flame retardant and wood flour on the physical, mechanical and combustion properties of fire materials were investigated.Saponin (SP), ammonium polyphosphate (APP) and pentaerythritol (PER) were used as intumescent flame retardants.0-10% wood flour, 0-18% APP and 0-6% PER were used in production.SP was used at 0-2-4-6-8% ratio to determine the effect on the physical, mechanical and fire properties of the composite material.A total of 20 different combinations of composite materials were produced.The density value, tensile strength (TS), tensile modulus of elasticity (TM), elongation at break (EB), flexural strength (FS), flexural modulus (FM), impact strength (IS), horizontal burning and limit oxygen index (LOI) properties of the produced composites were determined.According to the test results, with the addition of wood flour, APP/PER and SP, there was a decrease in tensile strength and elongation at break values, while there was an increase in tensile modulus of elasticity, flexural strength, flexural modulus and impact strength values.An increase in the density of the samples was detected with the addition of fillers.Addition of APP/PER to composite materials improved their fire properties.In the horizontal combustion test, the flame did not progress and was extinguished in the APP/PER added samples.A decrease in burning rate and an increase in LOI value were detected with the increase in SP usage rate.
