摘　　要：采用红磷阻燃母料(RPM440)阻燃的30%玻纤增强尼龙66,其氧指数只有27.2%,为了提高阻燃尼龙66材料的氧指数使其达到28%以上,在该阻燃材料体系中添加一些其他的无卤阻燃剂或阻燃协效剂,如氰尿酸三聚氰胺盐(MCA)、有机纳米蒙脱土(OMMT)。结果表明,当采用RPM440,添加4%MCA,OMMT质量分数分别为2%和3%时,都可以提高阻燃材料的氧指数达到28%以上;当采用RPM440与另一种红磷阻燃母料(RPM440W)复配,或单独采用RPM440W并添加3%OMMT也可以提高阻燃材料的氧指数达到28%以上。The oxygen index value of red phosphorus masterbatch （RPM440） flame retardant reinforced nylon 66 with 30% glass fiber was only 27.2%. In order to improve the oxygen index of the flame retardant materials of above 28% , some other non-halogen flame retardant or flame retardant synergistic agent in the flame retardant materials were added, such as melamine cyanurate （MCA） and organic nano montmorillonite （OMMT）. The results indicated that, when using red phosphorus flame retardant masterbatch RPM440 with MCA content of 4% and OMMT content of 2% or 3%, the oxygen index of the flame retardant materials could reach above 28%; when using composite red phosphorus flame retardant masterbatch of RPM440 and RPM440W, or using RPM440W with OMMT content of 3%, the oxygen index of the flame retardant materials could be also improved above 28%.
