摘　　要：采用涂覆法制备了基于可膨胀石墨的阻燃纸板,运用氧指数(OI)测试方法评价纸板的阻燃性,探讨了EG/MH/Na2SiO3·9H2O型复合阻燃剂中可膨胀石墨(EG)、氢氧化镁(MH)及硅酸钠(Na2SiO3·9H2O)用量对OI的影响。研究结果表明,优化后的复合阻燃剂配方为EG 10g,MH 5g,Na2SiO3·9H2O水溶液中Na2SiO3·9H2O 50g,水50g。阻燃剂搅拌混合均匀后涂覆于瓦楞纸板上,采用0.10mm的涂布厚度,可以使瓦楞纸板具备阻燃效果,其OI为28.3%,属于难燃级别。Flame resistant paperboard based on expandable graphite was synthesized through coating method .The oxygen index （OI） was tested to evaluate the flame resistant properties of the paperboard .T he influences of the contents of expandable graphite （EG ） ,the magnesium hydrate （M H） and Na2 SiO3？9H2 O contained in the composite flame retardant to the OI were investigated .Results showed that the optimal formula for the composite flame retardant is EG 10 g ,M H 5 g ,sodium silicate 50 g and water 50 g .The composite flame retardant with 0 .1 mm thickness was coated on the surface of corrugated paperboard . The modified corrugated paperboard ,with OI of 28 .3% ,exhibits a superior flame resistant property .
