摘要/Abstract

摘要： 采用四乙氧基硅烷（TEOS）作为改性修饰剂，分别对季戊四醇（PER）和聚磷酸铵（APP）进行表面改性，制备得到膨胀型阻燃剂（IFR），对改性后的IFR进行了红外光谱及热失重分析等表征，确认了硅的引入；向改性阻燃剂中加入纳米氧化镧（La2O3）作为阻燃协效剂，然后与聚丙烯（PP）混合，制备了疏水性膨胀型阻燃PP；研究了改性前后复合阻燃剂对PP阻燃性能和力学性能的影响。结果表明，改性后的阻燃体系表现出了较好的疏水性能，加入协效剂La2O3后，材料的阻燃性能和力学性能均较改性之前有所提高。

Abstract: Pentaerythritol and ammonium polyphosphate were surface-modified with tetraethoxysilane to prepare a series of intumescent flame retardants (IFR). The surface modification effect was confirmed by FTIR and TGA analysis. Nano Lanthanum Oxide (La2O3) were added into the modified flame retardants as a synergistic additive for flame retardancy and then melt blended with polypropylene (PP) to prepare the hydrophobic flame-retardant PP. The modification technology, the flame retardant and mechanical properties of polypropylenes were investigated. The results indicated that the hydrophobic properties of the modified PP were improved, and their flame-retardant and mechanical properties were improved considerably with the addition of La2O3.
