摘要
应用超细Al(OH)3阻燃剂进行了阻燃中密度纤维板(MDF)的试验,并利用锥形量热仪(CONE)对超细Al(OH)3阻燃剂处理中密度纤维板的燃烧性能进行了研究。结果表明:随着超细Al(OH)3阻燃剂用量的增加,引燃时间延长,释热速率、释热总量、有效燃烧热、平均质量损失速率、比消光面积和发烟总量等均有不同程度降低。其中,比消光面积和发烟总量降低最明显,说明添加Al(OH)3阻燃剂对MDF的抑烟效果较好,也验证了Al(OH)3良好的抑烟效果。在本试验中,超细Al(OH)3对抑制MDF的燃烧释热表现出一定作用效果,在最高阻燃剂用量条件下,释热总量降低40%左右。
An experiment was conducted to study the burning behaviors of medium density fiberboard(MDF)treated with Al(OH)3 superfines by cone calorimeter.Results showed that,with the addition amount of Al(OH)3 superfines increasing,ignition time,heat release rate(HRR),total heat released(THR),effective heat of combustion(HOC),mass loss rate(MLR),specific extinction area(SEA),and total smoke production(TSP)all decreased.Among the burning behaviors,the decrease of SEA and TSP was the most significant,which indicates that MDF treated with Al(OH)3 superfines has good smoke suppression properties.Al(OH)3 superfines have some effect on the heat release of treated MDF,and the THR reduced by 40% at the highest addition amount in this experiment.
