摘　　要：将苯乙烯-马来酸酐无规共聚物(SMA)与有机蒙脱土(OMMT)直接熔融复合,得到插层型SMA/OMMT纳米复合材料。采用水平燃烧、热重分析、高温处理等方法研究了纳米复合材料的燃烧行为。结果表明:与SMA相比,SMA/OMMT纳米复合材料在燃烧时不再熔融滴落,发烟量减小且能够自熄,水平燃烧级别由FH-3级升为FH-2级,材料的耐高温性能和阻燃性能显著增强。The intercalated nano-composite of styrene-maleic anhydride（SMA） random copolymer was prepared through direct melt compounding of SMA and organically modified montmorillonite（OMMT）. The combustion behavior of the SMA/OMMT nano-composite was investigated by horizontal burning, thermogravimetry and high temperature treatment methods. The data indicate that compared with SMA, melt drip phenomenon does not happen anymore when the nano-composite burns. And at the time, less smoke is released, flame is self- extinguishable and horizontal burning rate are raised from FH-3 to FH-2. The thermal stability and fire retardance of the nano-composite is enhanced remarkably.
