摘要:
为了提高环氧树脂(EP)的阻燃性能,通过四羟甲基硫酸膦(THPS)与对苯二胺在SiO2纳米粒子表面反应合成了有机/无机杂化多元素协同阻燃剂SiO2@聚四(4-氨基苯胺甲基)硫酸膦(SiO2@TAMPS),并对其结构进行了表征.将SiO2@TAMPS引入到EP中形成阻燃复合材料,其玻璃化转变温度(Tg)、最大分解温度(Tmax)和残炭率均有明显提升; 极限氧指数(LOI)可达30.3%,垂直燃烧等级为V-0级.结果表明,阻燃剂SiO2@TAMPS增加了残炭的石墨化程度,使炭层在高温下更稳定,并且起到了物理交联点的作用,增强了SiO2与EP的界面作用,提高了EP的强度和韧性.
Abstract:
In order to improve the flame retardancy of epoxy resin(EP),an organic/inorganic hybrid multi-element containing synergistic flame retardant silicon dioxide@poly(4-amino aniline methyl)phosphine sulfate(SiO2@TAMPS)was synthesized through tetrakis(hydroxymethyl)phosphonium sulfate(THPS)and p-phenylenediamine,and its structure was confirmed.SiO2@TAMPS/EP composites were prepared and it was found that the glass transition temperature,the maximum decomposition temperature,and the char yield of SiO2@TAMPS/EP composites increased.The limit oxygen index(LOI)value of composites could reach 30.3% and its vertical combustion rating was V-0.Experiment results further indicated that SiO2@TAMPS improved the graphitization degree of char residues,which has an improved stability at high temperature.Moreover,SiO2@TAMPS can act as crosslinking point to enhance the interface interaction between SiO2 and EP,thus improving the strength and toughness of EP.
