阻燃剂是阻燃技术在实际生活中的应用,它是一种用于改善可燃易燃材料燃烧性能的特殊的化工助剂,广泛应用于各类装修材料的阻燃加工中。经过阻燃剂加工后的材料,在受到外界火源攻击时,能够有效地阻止、延缓或终止火焰的传播,从而达到阻燃的作用。

3.1、人体十溴联苯醚水平已增长百倍

通过长期的对比研究,美国学者发现在同一人群中,体内十溴联苯醚同系物含量在逐年增加;在人类应用十溴联苯醚的30年内,十溴联苯醚在人体内的水平已经增长了100多倍。

这些数据表明,十溴联苯醚在人体内的蓄积量有加速上升的倾向,这自然会引起科学界的高度关注。

3.2、什么是多溴联苯醚

多溴联苯醚的最大用途是作为阻燃剂,在产品制造过程中添加到复合材料中去,以提高产品的防火性能。因为多溴联苯醚可在高温状态下释放自由基,阻断燃烧反应。其中十溴联苯醚(PBDE-209)是多溴联苯醚家族中含溴原子数最多的一种化合物,由于它价格低廉,性能优越,急性毒性在所有溴联苯醚中最低,所以在全球范围内使用最广,如用于各种电子电器和自动控制设备、建材、纺织品、家具等产品中。据统计,目前十溴联苯醚占阻燃剂总量的75%以上。

说起多溴联苯醚,多数人并不熟悉,但对等多氯苯及其衍生物多氯联苯却并不陌生。多年前,由于国际社会公认多氯联苯在环境中的残留周期特别长,能在生物及人类脂肪组织中蓄积,不仅各国纷纷禁用六六六、DDT,而且制定了非常严格的食品有机氯允许含量标准。多溴联苯醚恰恰与它们有着很多相似之处,只是因为多溴联苯醚的应用较晚,因此,人们对它的了解要比多氯联苯晚了半个世纪。
