摘　　要：将石墨进行氧化处理得到氧化石墨(GO),以甲醛、尿素及GO为原料,通过两步反应合成了GO-MUF新型阻燃剂,用红外光谱确定了化合物的化学键,研究了阻燃可发性聚苯乙烯(EPS)的阻燃性能。结果表明:当阻燃剂用量为25%时,阻燃EPS的氧指数和垂直燃烧等级分别达到36.6%和V-0级。此时,阻燃EPS的阻燃性能最佳。The graphite was modified to obtain modified graphite （GO）,then a kind of new GO-MUF flame retardant was synthesized by formaldehyde, urea and GO as raw materials. The bond of compound was determined by IR. The properties of the flame retardant expandable polystyrene （EPS） were researched. The results showed that： when the addi- tion amount of flame retardant was 25 %, flame retardant EPS oxygen index reached to 36.6 % and vertical burning reached to V-O grade. At this point,the comprehensive performances of flame retardant EPS were the best.
