摘　　要：研究三氧化二锑、八钼酸铵、锡酸锌和炭黑N330对氢氧化镁/氯丁橡胶共混胶阻燃性能的影响。结果表明:三氧化二锑和锡酸锌能提高共混胶的氧指数;三氧化二锑、八钼酸铵和锡酸锌能降低共混胶的烟密度,其中八钼酸铵的抑烟效果较好;三氧化二锑、八钼酸铵、锡酸锌和炭黑N330能降低共混胶的烟气毒性指数(CITg),其中添加锡酸锌的共混胶CITg较小。The effects of antimony trioxide, ammonium octamolybdate, zinc stannate and carbon black N330 on the flame retardancy of magnesium hydroxide/chloroprene rubber compound were studied. The results showed that antimony trioxide and zinc stannate improved the oxygen index of the compound. Antimony trioxide, ammonium octamolybdate and zinc stannate reduced the smoke density of the compound, and ammonium octamolybdate showed the best smoke suppressing effect. Antimony trioxide, ammonium octamolybdate, zinc stannate and carbon black N330 could reduce the toxic gas index （ CIT~ ） of the compound, and the compound with zinc stannate showed the smaller CIT8.
