摘　　要：将稻壳Si O2与含膦阻燃剂甲基环己基次膦酸铝[Al(MHP)]应用到环氧树脂(EP)中,着重研究了Si O2的添加量对Al(MHP)/EP体系的阻燃协效作用。结果显示,热分解过程的产物主要是含磷和硅的化合物,证实了富含磷、硅的化合物主要通过凝相机理发挥阻燃作用。稻壳Si O2显示出比较优异的协效作用和成碳性。Rice husk silica （RHS） and phosphorus-containing flame retardants aluminum methylcyclohexylphosphinate [ Al（MHP） ] were applied in epoxy resin （EP） , the synergistic flame retardant effect of the amount of silica for Al （MHP） / EP system was investigated. The results turned out that the products of thermal decomposition process were phosphorus and silica-containing compounds, it confirmed that the carbon layer which was rich in phosphorus and silicon displayed a condensed phase flame retardant mechanism. RHS revealed a greater synergistic effect and excellent char formation ability.
