膨胀型沥青阻燃剂阻燃性能研究

On Flame Retardant Performance of Intumescent Asphalt Flame Retardant

在分析阻燃沥青阻燃机理的基础上,结合阻燃剂的使用要求及发展趋势,选用膨胀型阻燃剂IFR制备阻燃沥青。采用极限氧指数、协同效率和阻燃价值等指标评价了阻燃剂对SBS改性沥青的阻燃效果,通过分析单一阻燃剂、二元复配、三元复配体系的阻燃效果,确定膨胀型阻燃体系的最佳复配比。

Based on the flame-retardant mechanism of modified asphalt and requests and development trend of flame retardants,the paper chose IFR to make flame-retardant asphalt.Indicators as limiting oxygen index,synergistic efficiency and flame retardant value were employed to evaluate the flame retardant effectiveness of SBS modified asphalt.After analyzing the flammability of a dollar flame-retardant,binary formulation,ternary formulation system,the optimum composite ratio was determined.
