摘要
针对氢氧化镁、硼酸锌、三氧化二锑等常用的阻燃抑烟剂对在软聚氯乙烯燃烧时的热释放速率和一氧化碳释放量进行了研究 ,发现氢氧化镁和硼酸锌虽然可以降低材料的热释放性能和发烟量 ,但是会大大增加烟气中一氧化碳的释放量 ;而三氧化二锑会增加材料的发烟量 。
The influence of several common flame retardants and smoke suppressan ts such as magnesium hydroxide, zinc borate and antimony trioxide on combustion properties including heat release rate and carbon monoxide generation in flexible PVC burning is reviewed. Results show that the presence of magnesium hydroxide and zinc borate reduces heat release rate and smoke emission, but greatly increases carbon monoxide generation in the smoke. Antimony trioxide increases smoke emission, but greatly decreases carbon monoxide generation in the smoke.
