阻燃剂是什么?

阻燃剂添加到制造材料中,如塑料和纺织品,表面尾料和涂层抑制、抑制或延迟火力生产以防止火传播阻燃剂可与基材混合(附加阻燃剂)或化学绑定(活性阻燃剂)

有效性

阻燃化工减少家庭大火中消费品易燃性的有效性有争议性。Advocates for the flame retardant industry, such as the American Chemistry Council`s North American Flame Retardant Alliance, cite a study from the National Bureau of Standards indicating that a room filled with flame-retarded products (a polyurethane foam-padded chair and several other objects, including cabinetry and electronics) offered a 15-fold greater time window for occupants to escape the room than a similar room free of flame retardants.However, critics of this position, including the lead study author, argue that the levels of flame retardant used in the 1988 study, while found commercially, are much higher than the levels required by TB 117 and used broadly in the United States in upholstered furniture.

另一项研究结论阻燃剂是有效工具,可减少消防风险而不产生有毒排放

1980年代数项研究测试全件家具点火,装饰类型和填充类型不同,包括不同的阻燃剂配方特别是,他们研究最大热释放和时间最大热释放,这两个关键火危险指标研究发现,织物类型对易点燃作用极大,棉填料比聚氨酯泡沫填充值低得多易燃性,跨行器间材料大大降低了点火易易易易性。 他们还发现,虽然一些阻燃剂配方降低了点火易易易易性,但满足TB117的最基本配方效果极小。聚氨酯泡沫协会议事录报告显示开火和香烟测试无益,泡沫垫处理阻燃剂满足TB117然而,其他科学家支持开火测试
