摘要

以七水合硫酸亚铁、氨基三亚甲基膦酸(ATMP)为原料,合成了氨基三亚甲基膦酸铁(Fe²⁺-ATMP)阻燃剂,将其引入硬质聚氨酯泡沫(RPUF),制备了阻燃RPUF。采用热重分析仪对材料进行性能表征,基于质量损失率和热解动力学分析Fe²⁺-ATMP阻燃剂添加量对RPUF热稳定性的影响。结果表明:Fe²⁺-ATMP阻燃剂的适宜添加量为5%～10%(质量分数);随着阻燃剂添加量的增加,RPUF的热稳定性和残炭率提高,表观活化能呈现先增大再减小的趋势。

Abstract

The amino trimethyl phosphonate iron (Fe²⁺-ATMP) flame retardant was synthesized from ferrous sulfate heptahydrate and amino trimethyl phosphonic acid (ATMP),and was further introduced into rigid polyurethane foam (RPUF) to prepare a flame retardant RPUF.Thermogravimeter was used to characterize the properties of this RPUF,and the effect of Fe²⁺-ATMP on the thermal stability of RPUF was analyzed based on mass loss rate and pyrolysis kinetics.The test results indicated that the optimum amount of Fe²⁺-ATMP flame retardant was 5%～10% (mass fraction).With the increase of the amount of flame retardants,the thermal stability and carbon residue rate of RPUF were improved,and the apparent activation energy first increased and then decreased.
