摘要

将2-羧乙基苯基次膦酸铝(CEPPAAl)与有机蒙脱土(OMMT)复合,制备了OMMT-CEPPAAl纳米复合阻燃剂,并用XRD和FT-IR对阻燃剂结构进行了表征。将复合阻燃剂用于制革工艺复鞣工段。对皮革的极限氧指数(LOI)、垂直燃烧和锥形量热的研究表明,当阻燃剂中OMMT含量为20%时,阻燃皮革LOI达到33.0%,有焰燃烧时间和无焰燃烧时间几乎为0 s,最大热释放速率较空白皮革降低了25.9%。用SEM研究了残炭形貌及表面元素,结果表明OMMT-CEPPAAl可在凝聚相起阻燃作用。力学性能及收缩温度研究表明,加入OMMT-CEPPAAl,皮革保持了良好的力学性能和湿热稳定性。
        Aluminum carboxyethyl phenylphosphonate(CEPPAAl) and organic montmorillonite(OMMT) were combined to prepare OMMT-CEPPAAl nanocomposite flame retardant. The structure of the flame retardant was characterized by XRD and FT-TR. The composite flame retardant was used in the retanning section of leather processing. The limiting oxygen index(LOI), vertical combustion and conical calorimetry for flame retarded leather were tested, and the results showed when the OMMT content was 20% in flame retardant, LOI of flame retarded leather reached to 33.0%, flaming and flameless combustion time almost reduced to zero, and comparing with blank leather, the maximum heat release rate was reduced by 25.9%. residual carbon morphology and elements were investigated by SEM, and the results demonstrated that OMMT-CEPPAAl played role in the condensed phase. Mechanical properties and moisture and heat stability of leather were also studied, the results showed flame retarded leather maintained good mechanical properties and wet and heat stability.
