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。
The effects of various compound flame retardants with Sb_2O_3,such as Zn_3(BO_3)_2/Sb_2O_3,Al(OH)_3/Sb_2O_3 and MoO_3/Sb_2O_3,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 Zn_3(BO_3)_2/Sb_2O_3,while the physical properties changed little;the better flame retardance was obtained by using Al(OH)_3/Sb_2O_3,but MVQ vulcanizate would generate more smoke;and the smoke generated by MVQ vulcanizate could be reduced by MoO_3/Sb_2O_3,but the flame retardance didn't improve significantly,and the physical properties of vulcanizate deteriorated severely.
