金属氧化物对膨胀阻燃涂层耐火及成炭性能的影响
Effect of Metal Oxides on Fire Resistance and Char Formation of Intumescent Flame Retardant Coating
摘要
Abstract
Metal oxides (MO) can remarkably affect the char formation of intumescent flame retardants (IFR) during thermal decomposition, thereby improving the fire resistance property of IFR coatings. In present work, Fe2O3, ZnO and TiO2 were separately incorporated with caged bicyclic phosphates based IFR in epoxy coating, and their effects on fire resistance and char formation of the IFR coating were investigated. Back temperature test results showed that MO worked synergistically on improving fire resistance of the coating and their effectiveness of improvement followed the trend of Fe2O3>ZnO>TiO2. Thermogravimetric analysis (TGA), laser Raman spectroscopy (LRS) and X-ray photo-electron spectroscopy (XPS) results revealed that MO promoted the formation of pseudo-graphic char with improved thermal stability which still survived at high temperature, and their effectiveness of promotion also followed the trend of Fe2O3>ZnO>TiO2.关键词
