Deposition of Antimony Trioxide on the Composite Surface to Increase Its Flame Retardancy

Ali I. Al-Mosawi


In the present work, the preparation method of antimony trioxide and its thermal properties were extracted, as well as identified the manufacturing method to form an insulation layer from this oxide as a thickness of the covering layer (2 mm), deposited on the composite material consisting of unsaturated polyester resin and glass fiber which acts as a paste and take for the material to the insulation and flame retardant oxide. Thermal erosion test was performed to assess the functioning of the antimony oxide efficiency to flame retardants. The result obtained from erosion test done at (2000 °C) is an evidence that the antimony trioxide has an efficiency of as a flame retardant material at elevated temperatures.
