摘　　要：以二月桂酸二丁基锡为催化剂,用磷酸三苯酯表面改性纳米二氧化硅(SiO_2),制备了聚丙烯(PP)/表面改性纳米SiO_2复合材料。采用红外光谱仪、差示扫描量热仪、热重分析仪和万能材料试验机等进行表征。结果表明:有机磷改性后SiO_2粒子的表面羟基消失,有机磷的接枝率为87.71%,改性纳米SiO_2能够改善PP复合材料的热稳定性和阻燃性能。Using dibutyltin dilaurate as catalyst,the nano-silica was surface modified directly with triphenyl phosphate,and was inttroduced into polypropylene（PP） forming composites.The modified nanosilica and the composite were investigated by Fourier transform infrared spectrometer（FTIR）,differential scanning calorimeter（DSC）,thermal gravimetric analyzer（TG）,universal material machine,and so on.It was found that the surface of modified nano-silica had no hydroxyl groups,the grafting degree of organic phosphorus on silica was 87.71% and the modified SiO2 could improve the thermal stability and flame retardant propertyof PP composite.
