将气相SiO2与含膦阻燃剂复配，应用到环氧树脂（ EP）中，着重研究了该复合材料的阻燃性能、热分解性能及玻璃化转变温度（ Tg），结果表明当气相SiO2含量为3％时，复合材料的氧指数值达到28.3％，垂直燃烧通过UL94 V－0标准。在热分解过程中，各组分之间相互作用，复合材料的玻璃化转变温度比纯EP的要高，残炭率也增加。可见气相SiO2起到一定的辅助阻燃作用。

The gas phase silica and phosphine-contained flame retardants were applied epoxy resin ( EP).The flame retardant、 thermal decomposition property and glasnsition temperature ( Tg ) of composites were investigated.Results showed that when the gas phase silica content of 3%, the EP composite material achieved the optimal retardancy ( limited oxygen index value of 28.3% and UL94 V-0 rating ) .There were interactions between each component in the thermal decomposition process.It was found that the glass transition temperature ( Tg ) of the composites was higher than neat epoxy resin.Composites carbon residue rate was increased.The gas phase silica showed excellent synergistic effect.
