| 中文摘要: |
| 分别研究硼酸锌/三氧化二锑、氢氧化铝/三氧化二锑和三氧化钼/三氧化二锑并用体系对甲基乙烯基硅橡胶（MVQ）硫化胶阻燃性能和物理性能的影响。结果表明，硼酸锌/三氧化二锑并用体系可有效提高MVQ硫化胶的阻燃性能，并能保持较好的物理性能；氢氧化铝/三氧化二锑并用体系的阻燃效果十分显著，但MVQ硫化胶的发烟量稍大；三氧化钼/三氧化二锑并用体系虽可减小MVQ硫化胶的发烟量，但阻燃效果不明显，且硫化胶的物理性能受损严重。 |
| 英文摘要: |
| The effects of various compound flame retardants with Sb2O3，such as Zn3(BO3)2/Sb2O3，Al(OH)3/Sb2O3 and MoO3/Sb2O3，on the flame retardance and physical properties of MVQ vulcanizate were investigated.The results showed that the flame retardance of MVQ vulcanizate improved significantly by using Zn3(BO3)2/Sb2O3，while the physical properties changed little；the better flame retardance was obtained by using Al(OH)3/Sb2O3，but MVQ vulcanizate would generate more smoke；and the smoke generated by MVQ vulcanizate could be reduced by MoO3/Sb2O3，but the flame retardance didn't improve significantly，and the physical properties of vulcanizate deteriorated severely. |
