Abstract AR
تم التحري أداء بروم في أكسيد ديكابروثنائي فينيل (DBBO) كمثبط لاشتعال راتنج عديد إستر غير مشبع (UP) و ذلك بمفرده و بوجود أكسيد الألمونيوم (A12O3) باستعمال UL-94V و مؤشر الأكسجين المحدد Limiting Oxygen Index (LOI).
و تم تقييم السلوك الحراري للأنظمة الناتجة باستعمال تقنيات التحليل الحراري.
و قد أظهر DBBO أداء مرضيا لتثبيط اشتعال UP، خاصة عند استعماله بكميات أكبر من 30 % وزنا.
و على النقيض من ذلك لم يظهر أكسيد الألمونيوم تأثيرا يذكر في خفض الاشتعالية.
و أظهرت معالجة UP بمخاليط تحتوي على كميات مختلفة من DBBO و الألومينا أن أفضل أداء لهذه المخاليط في تثبيط الاشتعال يكون في الحالات الغنية بمادة DBBO.
إن التوليفة العظمى للمضافين قد لوحظت عند نسبة الوزنية من DBBO إلى A12O3 6:5.
و قد وضع التفسير المحتمل لهذه التوليفة.
فهي تعزى جزئيا إلى تكوين أنواع من هاليد الألمونيوم تعزز من سرعة إطلاق الهالوجين من المركب المهلجن مما يفضي إلى تقليص اشتعالية الراتنج.
Abstract EN
The Bromine performance of decabromobiphenyl oxide (DBBO) as a flame retardant for unsaturated polyester resin (UP) had been investigated in its own and in the presence of aluminum oxide (Al 2O3) using UL-94V and Limiting Oxygen Index (LOI).
Thermal behaviors of the resulted systems were evaluated using thermal analysis technique.
DBBO showed a satisfactory fire retardant performance for UP, particularly when used at a loading higher than 30 wt%.
In contrast aluminum oxide has no significant effect on the reduction of the flammability.
Treatment of UP with mixtures containing different portions of DBBO and Alumina showed that, the best performance of these mixtures as a flame retardant occurred when the mixture is rich in DBBO.
The maximum synergism between the two additives has been observed to occur at a weight ratio of DBBO to Al2O3 of 5 : 6.
A possible explanation for the observed synergism between the two additives was given.
The synergism was partly attributed to the formation of aluminum halide species which enhance the rate of halogen released from the halogenated compound and consequently reduce the flammability of the resin.
