Abstract

In this work, the flame retardant influences of colemanite and boron oxide are investigated in huntite-hydromagnesite (HH) containing plasticized poly (lactic acid) (PLA) biocomposites. The composites are characterized using limiting oxygen index (LOI), horizontal (UL 94 HB) and vertical (UL-94 V) burning tests, mass loss calorimeter and thermo gravimetric analysis (TGA). The addition of colemanite causes enhanced fire retardant performance with higher UL-94 V rating and LOI value and lower pHRR value. V0 rating and the highest LOI value is observed with the addition 1 wt % colemanite. When the concentration of colemanite reaches to 3 and 5 wt %, the samples get V1 rating. When the concentration of colemanite reaches to 5 wt %, pHRR and avHRR values are lower than those of the reference sample. The addition of boron oxide caused only improvement in LOI value. The highest LOI value (33.2) is observed in 5 and 10 wt % boron oxide containing samples.

Özet

Bu çalışmada, Huntit-hidromanyezit (HH) içeren poli (laktik asit) (PLA) biyokompozitlerinde kolemanit ve bor oksidin alev geciktirici etkileri araştırılmıştır. Kompozitler, sınırlayıcı oksijen indeksi (LOI), yatay (UL 94 HB) ve dikey (UL-94 V) yanma testleri, kütle kaybı kalorimetresi ve termo gravimetrik analiz (TGA) kullanılarak karakterize edilmiştir. Kolemanit ilavesi ile daha yüksek UL-94 V derecesi, LOI değeri ve daha düşük pHRR değeri ile alev geciktirici performasında iyileşmeye neden olmuştur. V0 derecesi ve en yüksek LOI değeri, ağırlıkça %1 kolemanit ilavesinde görülmüştür. Kolemanit konsantrasyonu ağırlıkça %3 ve %5 olduğunda numunelerde V1 derecesi elde edilmiştir. Kolemanit konsantrasyonu ağırlıkça %5'e ulaştığında, pHRR ve avHRR değerleri referans numunenin değerlerinden daha düşük çıkmıştır. Bor oksit ilavesi sadece LOI değerinde iyileşmeye neden olmuştur. En yüksek LOI değeri (33,2) ağırlıkça %5 ve %10 bor oksit içeren numunelerde görülmüştür.
